2. General safety precautions
2.1. Fiber optic cables may be damaged if bent or curved to a radius that is less than the recommended
minimum bend radius. Always observe the recommended bend radius limit when installing ber optic cables and
patch cords.
2.2. Exposure to laser radiation can seriously
damage the retina of the eye. Do not look into the ends of any optical ber. Do not assume the laser power is turned off or that the ber is disconnected at the other end.

4. Fiber indexing
4.1. Fiber indexing building blocks
CommScope’s ber indexing system consists of terminals and connectorized 12 strand ber cables using hardened connectivity. It allows to build the FTTX network in the outside plant environment faster, with plug and play
installation.
The exact same components (ber indexing terminal
and the corresponding drops to the homes) are installed
between a ber distribution hub (FDH) and subscribers (homes) in a daisy chain architecture. Several daisy
chains are connected to the hub. Each chain consist of
up to 12 ber indexing terminals and d istributes services
to up to 96 subscribers (homes). Drop cable assemblies
transport the optical signal from the ber indexing
terminal to the home.
4.2. Reverse feed
When a second cable is connected from the hub (FDH) to
the last terminal , the signal runs “backwards” toward the rst terminal. This makes additional bers available that
can be used to add subscribers or roll out new services.
More information on how to make this installation, can be
obtained in section 7.2.5.
4.3. Fiber indexing technology
Indexing refers to the shifting of a ber’s position - from one multi-ber connector to the other - within each
terminal.
The process begins with a 12 ber cable from the
ber distribution hub (FDH) entering the rst ber indexing terminal.
Inside the terminal, the bers divide and the signal on the ber on the rst position is routed to a splitter (1:4
or 1:8) for servicing local customers.
All other bers are indexed - advanced one position
in the order - so that the number 2 ber shifts to the number 1 position, ready to be routed to the subscribers at the next terminal.
The bers are re-combined using a 12 ber HMFOC. The last ber position of the 12 ber HMFOC
becomes accessible via the reverse path optical port.

5.1.2. DLX connector housing
This housing contains DLX adapters. (See chapter 11
for installation guidelines) for the single-ber drops and
an HMFOC adapter (male) to connect the terminal to the
next terminal. (See chapter 10 for installation guidelines). The input for these adapters is a 12 ber cable that
enters the terminal through a sealed opening located at the bottom of the terminal. The stub cable is terminated with an HMFOC connector (female). The terminal ships with its UMB.
This housing is also used for the branch terminal
conguration that doesn’t contain single-ber drops. Only
2 HMFOC ports are available in this model (see section
5.2.4)
5. Fiber indexing terminal
All indexing terminals have a hardened, weather resistant plastic housing. The housing type depends on the adapter type of the single-ber drop port, either full size hardened or DLX. Both housing types use HMFOC adapter(s) for the multi-ber connection.
5.1. Housings
5.1.1. Full size hardened connector housing
This housing contains full size hardened adapters (see chapter 12 for installation guidelines) for the single-
ber drops and an HMFOC adapter (male) to connect the terminal to the next terminal. (See chapter 10 for
installation guidelines). The input for these adapters is a
12 ber cable that enters the terminal through a sealed
opening located at the bottom of the terminal. The stub cable is terminated with an HMFOC connector (female). The terminal ships with its UMB.

5.2.2. Standard indexing terminal 1:4 splitter with reverse port
In this conguration, the terminal will drop the rst ber from the incoming 12 ber strand. This ber will be
routed to an integrated 1:4 splitter. The outputs of this splitter are DLX adapters or full size hardened adapters
(depending on the housing type). The others 11 bers from the incoming 12 ber strand cable will proceed
unsplit and be terminated on a HMFOC adapter port,
together with the ber coming from the reverse port. The ber coming from the reverse port will take # 12 of the outgoing 12 ber HMFOC, the incoming ber # 2 will take # 1 of this outgoing 12 ber HMFOC.
The HMFOC adapter port is colored green and indicated with an ‘A’ on the terminal. The reverse port is colored red and indicated with a ‘R’ and the terminal.
Image below shows the schematics inside the terminal.
The 12 ber strand cable terminated on a female HMFOC
of this terminal is connected to the green HMFOC adapter port of its up-stream terminal (to the FDH in case
of the rst terminal of the chain), a forward feed path is
created. 4 subscribers (homes) can be fed around this
indexed terminal by connecting a connectorized drop cable (DLX or full size hardened) to one of the 4 black
dust cap adapter ports.
Up to 12 indexed terminals can be connected one after the other (link installation).

5.2.4. Indexing only terminal with reverse port
The indexing terminal is also available without an
integrated splitter. In this case the unsplit signal of the
rst ber of the incoming chain, goes to a single drop (black dust cap). This single drop can be connected to a
more peripheral terminal where splicing and or splitting
is performed. This topology enables a greater spatial
coverage though the possible number of drops remains the same for each chain. Images below shows the schematics inside the terminal and the color code of the adapters of this terminal.

The daisy chaining installation can continue from each
HMFOC adapter port, but with a reduced chain in either
direction as dened by the ber branch quantity.
Although this terminal has no reverse feed adapter port,
the reverse feed functionality is still available in the
reduced chains.
5.2.6. Multi-use
5.2.6.1. Internal splitter with pass-thru bers
Multi-use ber terminals are designed to deliver splitter based services and/or traditional “unsplit” services. The splitter (if present) is always connected to the rst ber of the incoming 12 ber stand. The outputs of the splitter are indicated with a black dust cap. Adapters with an orange dust cap indicate a straight pass-thru ber. It is a ber dropped of from the incoming 12 ber chain, but unsplit (it is a regular ber coming from the hub).
Example below shows the rst ber dropped of routed
to an integrated 1:4 splitter and the second and the third
ber dropped of directly routed to the adapter port. The other 9 bers from the incoming 12 ber strand continue via the green HMFOC adapter port where ber 4 of the incoming strand will take in position 1 in the adapter port. 3 bers from the red reverse port will take in
positions 10,11 and 12 in the green HMFOC port. In this case the reverse port is also an HMFOC adapter port.
In this example, link installation decreases to 4 terminals
in a chain.

5.2.5. Indexing branch terminal
The indexing branch terminal enables dividing the incoming 12 bers into 2 HMFOC adapter ports. This conguration provides more exibility in the distribution network as greater spatial coverage area can be
achieved. Neither the reverse feed port nor the single
drop ports are included on an indexing branch terminal.
The image below shows the schematic inside the terminal:
The rst bers from the incoming 12 ber tail are always
routed to the blue HMFOC connector, indicated with
letter B, the other bers are routed to the green HMFOC,
indicated with letter A.
The bers always take in the rst ber positions in the multi ber connector. Image above illustrates the rst 3 bers from the incoming 12 ber tail (input) routed to the rst 3 positions in the blue HMFOC connector, the last 9 bers from the incoming 12 ber tail routed to the rst
positions in the green HMFOC connector. The remaining positions of the green and blue HMFOC are unused.
The Indexing branch terminal can be delivered with following division of the incoming 12 bers.
B (blue) A (green)
1,2 3 to 12
1 to 3 4 to 12
1 to 4 5 to 12
1 to 5 6 to 12
1 to 6 7 to 12
The model number (catalogue number) indicates the
quantity of bers going to the blue HMFOC:
For example NDX-B3 indicates that the rst 3 bers of the incoming 12 ber strand are routed to the blue HMFOC and the last 9 bers are routed to the green HMFOC taking in the rst positions (position 1-9) in the
connector.

5.3. Cable stub
5.3.1. Cable type and length
The cable stub on the terminal is an all-dielectric at drop
cable terminated with a female (non-pinned) HMFOC.
The cable outer dimensions are 8 x4.3 mm (0.31x0.17
inch).
Cable length that can be ordered, range from 3 to 609 m (10 to 2000 feet). See ordering guide for details.
Terminals with cable stub lengths less than 30.5 m (100 feet) are shipped coiled. When the cable stub is 30.5 m (100 feet) or longer, the terminal is shipped on a spool,
with the terminal secured on the spool ange as shown in
the image below:
A serial number label is applied on the cable
approximately 0.2 m (8 inch) from the connector body.
See image below.
5.2.6.2. 24 ber Indexing terminals
Twenty-four ber Indexing terminals are designed to deliver bulk ber into a distribution area where split and
unsplit services are needed. On board splitters have been
removed in favor of external splitters. Fibers are allocated into two groups. Fibers 1-12 are congured to the standard indexing model. Fibers 13-24 are congured as pure pass-thru without indexing. This segregation allows for the express delivery of bers independent of indexing architectures when necessary and replenishment of ber when the indexing string becomes exhausted.
Example below shows the rst 4 bers dropped of. The signal is unsplit. The ber in each of these drop off port is a straight pass-thru ber. The dust cap is orange. Fiber 5 of the incoming 12F strand takes in position 1 of the outgoing HMFOC adapter port (A1). 4 bers of the reverse port take in position 8,9,10, 11 and 12 in that
adapter port.
Indexing terminals exhaust themselves once 12 bers have been allocated. This may happen in as few as three links or as many as 12 links dependent on how the bers are distributed along the way. Twenty-four ber terminals have the capacity to replenish an indexing string by harnessing the express group on the “A2” port. This is achieved by attaching the next indexing terminal to the “A2” port. If the next terminal is a twenty-four ber
terminal then the tail connectors will be swapped (e.g.
“a1” tail connector to “A2” port and “a2” tail connector to “A1” port).

5.5.5. Cleaning kit HMFOC
To clean the HMFOC adapter and connector, a US Conec HMFOC connector cleaning tool (PN 15639)
can be ordered at US Conec.
6. Network design with the indexing terminals
The different congurations of the indexing terminals can be combined to provide all the necessary exibility and maximize the capacity of the distribution network. First splitting level occurs typically in a Mini-FDH 3000
with 96 ports or an OSP closure (FOSC/FIST/TENIO) with additional HMFOC connectors. The second splitting
level occurs within the indexing terminals, the different congurations are explained in section 5.2.
Indexing chains always start with terminal one and build
outward in procession to a value no greater than twelve.
Indexing chains always provide the next ber to the next terminal (i.e. Terminal 1 will use ber 1 within the “chained” assembly).
In order to build an optimized network utilizing indexing
terminals, the following items should be considered prior
to beginning the network design:
Locate and identify all Customers to have an overview of all area to be covered/deployed.
Clear up all drawing nomenclature: hand holes, poles, ducts, terminals, etc.
Identify feeder ber cables availability. If available,
dene the ber count & type of cables.
Locate nearest CO, Node or HUB to determine the
maximum distance allowed within the optical budget
Take into consideration, drop cable distances/routes
Identify any network deployment restriction: Poles,
aerial capacity, underground ducts
Discuss the best location for Indexing Terminals (aerial, pole, wall, manhole)
Consider the maximum number of services per
indexing terminal
Split ratio: Specied by project
7. Installation
7.1. Tools and materials required
The following basic tools, auxiliary equipment, and materials are required for the installation of the indexing
terminals:
Vertical roller reel (if the terminal is mounted on a cable spool)
216B key tool (used to open optical port dust cap)
Hardened connector/adapter cleaning kit (FHD-ACC-CLNKIT1)
US Conec HMFOC connector cleaning tool (PN
15639)
Utility knife
Cable pulling equipment
Appropriate fasteners to mount the UMB and tools to install the fasteners
“P” clamps for self supporting aerial installations. Cable routing rings or fasteners (see local practices). Cable can be lashed for messenger applications.
5.4. Universal Mounting bracket
Each terminal is supplied with the Universal Mounting
Bracket (UMB) which is used for mounting the ber indexing terminal. The UMB may be attached to various mounting surfaces using a variety of fasteners as will be explained in section 9. The UMB is housing specic and exist for the full size
hardened housing as well as for the DLX housing.
5.5. Accessories
5.5.1. Strand mounting kit
To secure the terminal to a strand, a strand-mount
bracket kit is available and must be ordered separately. Refer to Universal Mounting bracket Strand-Mount
Installation InstructionADCP-96-124 for the installation procedure. Section 9.5 provides some info about how to
use this strand mounting kit.
5.5.2. NDX-POLE-BRKT
To store excess cable in aerial applications, an NDX­POLE-BRKT kit is available and must be ordered separately. If using the full size hardened connector housing, an adapter bracket must also be ordered when using the excess cable storage bracket (part number
NDX-4X3-ADPT-BRKT).
The bracket is secured with 1/4 inch thread size hardware to a pole. Excess cable can be looped around the bracket. When all excess cable is stored, the terminal
with its UMB can be slided in an upward direction into the
NDX-pole bracket.
5.5.3. 216B key tool
The opening to each optical port is sealed with a
threaded dust cap that prevents the entry of dirt and moisture. A standard 216B security tool can be ordered to
remove the dust cap.

Note: If using an enclosure such as a hand-hole or pedestal, refer to the instructions provided with the enclosure for any additional tools or equipment required.
7.2. Installation overview
To install the indexing terminals in the network and to build the indexing network, following main tasks must be
perfomed:
1. Mounting the terminal (refer to section 9) The terminal must be mounted on or within a suitable support base or enclosure. The UMB allows the
terminal to be mounted in a variety of applications
including the following:
• Hand-Hole (below ground)
• Pole-Mount (aerial)
• Strand-Mount (aerial)
• Pedestal (at nal grade)
2. Link installation (installing the HMFOC) The terminals connect to one another via a Hardened Multi-Fiber Optic Connector (HMFOC). The non­pinned tail connector (HMFOC) is routed to the up-
stream component like an FDH or a previous terminal for termination. The “green” capped MPO (pinned, male) in the body of the terminal housing receives the
downstream tail connector (non-pinned,female).
For the indexing branch terminal, the blue adapter
port is a capped MPO (pinned) which can receive the downstream tail from another chain. Refer to section 8 for cable handling recommen-
dations and refer to section 10 for making the
HMFOC connection.
3. Testing the indexing chain (refer to section 13)
After installing the indexing chain, the signal on the
drops should be tested to ensure a correct installation of the chain.
4. Drop cable installation and connection
After the indexing chain is set up, the single drop
connection can be made. Follow local practice for pulling and installing drop cables. Refer to the
instructions provided with the mounting system for drop cable entry and routing. Service is enabled by connecting the drop cable connectors to the black
dust cap adapter ports on the terminal (see section 11 and 12).
In the Indexing Only conguration, a splitter only terminal can be installed to the single black dust cap
adapter port. The subscribers will be connected to this splitter only terminal.
5. Reverse feed installation
If all indexing terminals are installed, a FO cable with
HMFOC connectors at both ends can be connected to the green dust cap adapter port of the last terminal and to a 2nd HMFOC connector of the FDH. Now,
all RED ports from all Indexing terminals can be
connected to subscribers. The red adapter port is a DLX or full size hardened connector, depending on the housing. For installation, refer to section 11 or
12).
6. Maintenance
Maintenance for the indexing terminal is limited
to cleaning the hardened adapters as needed to maintain optimal performance. Refer to section14.

To relieve strain on the HMFOC connection, CommScope recommends component coupling. Component coupling in optical cables is important to harmonizing the movement of the various cable
components created by stresses during installation, through thermal cycling and environmental loading.
Input: Loop the cable tail before entering the upstream terminal. Make 5 loops with a diameter of 152.4 mm (6 inch). Output: Also on the output component coupling is recommended, looping the cable 5 ½ loops (with
diameter 152.4 mm (6 inch)) adequately enhances the
coupling to prevent buffer tube movement.
Note: For applications where the cable is pulled, remove the coupling coils and reinstall when cable pull is
completed.
Overlength:
Always store overlength near the terminal where the
cable leaves the terminal. For pole mounting the NDX-
pole-BRT bracket can be used.
Cable pay off:
1. Determine the terminal’s nal location. Mount the spool
on a vertical arbor on that location and pull the tail to the
upstream network element (hub or terminal). Maximum
pulling force 444.8 N (100 lbs).
2. Secure the cable at the location of the upstream
network element (for example with a P-clamp attached to
a D-ring in aerial application).
The cable length from this securing point to the connector
should be long enough to make the HMFOC link
installation with correct cable bend and 5 loops to relieve strain on the connection.
3. Make the link installation (chapter 10) to the upstream network element and go back to the terminal.
4. Mount the UMB or NDX-pole-BRKT and secure the
cable (for example with a P-clamp attached to a D-ring in
aerial applications).

8. Cable handling
recommendations
Each terminal is equipped with an optical cable. Depending on the length of the cable, the dielectric cable
may be coiled up and placed in a box or it may be coiled
on a spool.
Coiled Cable Handling: Leave the terminal on top and in the center of the coil. Locate the free end of the cable and
then carefully uncoil the cable from around the terminal.
Spooled Cable Handling: If the dielectric cable is coiled
on a spool, remove the spool from the box. Leave the
terminal on top of the spool and place the spool on a
vertical arbor. Locate the free end of the cable. Carefully pull the cable away from the spool allowing the spool assembly to rotate about the vertical arbor.
Cable Bend Radius Limits: Take care to observe the
recommended minimum bend radius limits for the cable.
Always maintain a minimum bend radius of 76.2 mm (3
inch).
Pulling the cable: When pulling the cable into place,
do not exceed a pulling force of 444.8 N (100 lbs) on
the optical cable. Pulling on the cable should be done through the pulling cap, see picture below: When connector is mated – in service, pulling force is
max 111.2 N (25 lbs).
Span rating: the recommended span width is as followed:
m ft
NESC Light load Destrict 122 400
NESC Medium load Destrict 76 250
NESC Heavy load Destrict 46 150

9.2. Hand-Hole mounting
Hand-Hole Mounting (below ground) – A hand-hole
enclosure (examples shown in Figure below) is an OSP below-ground mounting system that may be used for any indexing terminal or other similar products. When installed, the top of the hand-hole enclosure is ush with
the top of the ground. Hand-hole enclosures consist of a base unit and a top cover. The base unit mounts in the ground. Cables and conduit enter the base unit from the bottom.

5. Store overlength near the terminal where the cable
leaves the terminal. For pole mounting the NDX bracket
can be used.
Note: The reverse option (cable spooled in opposite way to pay off the cable in the reverse direction - from upstream component to terminals nal position) is available.
9. Mounting the terminal
9.1. Disconnect the terminal from its
UMB
To install the terminal in several situations, the terminal is
supplied with its UMB (universal mounting bracket). The
UMB can be attached to various mounting surfaces using
a variety of fasteners. Multiple holes and slots are provided in the UMB to accommodate these variety of
fasteners. To reach these holes and slots, the terminal should be disconnected from its UMB. This can be done
by lifting the snap t.
Release the terminal and move it slightly upwards. Now the cable end can be taken out of the bracket:

Danger: Exposure to laser radiation can seriously damage the retina of the eye. Do not look into the ends
of any optical ber. Do not assume the laser power is turned-off or that the ber is disconnected at the other
end.
10.4.1. Remove dust caps
10.4.1.1. Field personnel must take care when proceed to remove dust caps at the HFMOC at the adapter plugs or cables, to prevent contaminant particles entering to the adapters or connector end-face.
10.4.1.2. Before removing dust cap, be sure to turn the terminal to a position where adapters are protected (i.e. for aerial application, adapters will face down), helping to prevent any particle/ dust to fall down and contami­nate the adapter. Before removing the terminals optical
port dust cap, clean any debris from around the indexing terminal optical ports, preferably using compressed air, to minimize the risk of introducing contaminants into the
optical port.
10.4.1.3. Use the 216B key tool (accessory) to unscrew the dust cap from the indexing terminal optical port. This is the green port, indicated with a letter A or the blue port, indicated with letter B.
10.4.1.4. For the cables, before taking out the dust cap,
take in consideration all possible precaution to prevent any particle to contact the end-face connector and, keep
the terminal with the adapters facing down to insert and tight the drop cable. Before removing the cable’s con-
nector dust cap, clean any debris from around the cable connector housing, preferably using compressed air, to minimize the risk of introducing contaminants onto the
ferrule.
10. Link installation (HMFOC)
10.1. Connector components
The HMFOC connector at the end of the terminal’s tail
is a hardened 12 ber connector that can be used for many applications. The primary application is to connect indexing terminals in cascade or to connect an indexing
terminal to the Fiber Distribution Hub (FDH) or Closure, to
extend the distribution network.
The connector on the tail is the non-pinned female type. The connector is protected by a dust cap. The O-ring on the connector body provide a water tight seal when the dust cap is in place. A pulling eye is provided in the end of
the dust cap for pulling the drop cable.

12.4.1.1. Field personnel must take care when proceed to remove dust caps at the Full size hardened connector at the adapter plugs or cables, to prevent contaminant particles entering to the adapters or connector end-face.
12.4.1.2. Before removing dust cap, be sure to turn the terminal to a position where adapters are protected (i.e. for aerial application, adapters will face down), helping to
prevent any particle/ dust to fall down and contaminate
the adapter. Before removing the connector dust cap,
clean any debris from around the drop cable connector housing, preferably using compressed air, to minimize
contaminants from being introduced onto the ferrule.
12.4.1.3. Use the 216B key tool (accessory) to unscrew
the dust cap from the indexing terminal drop port: one of the black ports with number 1 to 8 or the red port (reverse
feed).
12.4.1.4. For the cables, before taking out the dust cap,
take in consideration all possible precaution to prevent any particle to contact the end-face connector and, keep
the terminal with the adapters facing down to insert and tight the drop cable. Before removing the cable’s con-
nector dust cap, clean any debris from around the cable connector housing, preferably using compressed air, to minimize the risk of introducing contaminants onto the
ferrule.
12.4.1.5. Unscrew the coupling nut from the drop cable connector dust cap.
12.4.2. Full size hardened connector cleaning
Note: The connector and adapter come clean from the
factory and should not require additional cleaning before the rst connection.
If cleaning is required before installing the connector, follow procedure as described in section 14.3.
12.4.3. Install the connector
12.4.3.1. Inspect the optical port dust cap O-ring and
the drop cable connector O-rings for dryness and apply O-ring lubricant (MST-ACC-LUBE1) to the O-ring if dry.
Refer to Section 12.6 for the procedure.
Note: The optical port dust cap O-ring and the connec-
tor O-ring is pre-lubricated by the factory and should not require additional lubrication for the initial assembly.
12.4.3.2. Align the drop cable connector with the optical port. The pointer on the drop cable connector should line up with the notch on the optical port.
12.4.3.3. Insert the drop cable connector into the optical port. If the drop cable connector does not insert all the
way to the bottom of the port, rotate drop cable connector slightly to either side until it slides freely into place.
12.4.3.4. Thread the drop cable connector coupling nut
into the optical port and tighten coupling nut until nger
tight.

13. Testing
Testing ber indexing terminals is dependent on many
factors including the architecture of its end user. This
chapter will address a variety of methods suitable to test
a lead prior to and after it is in service.
The reader should consider some terminology within like; “Lead” refers to a single chain of terminals. “Upstream” refers to a position closer to the CO or head end or the direction light would be owing from a piece of
equipment.
“Downstream” refers to a position closer to the end of a lead or the direction light would be owing from a piece of
test equipment.
Indexing chains always start with terminal one and build
outward in procession to a value no greater than twelve.
Indexing chains always provide the next ber to the next terminal (i.e. Terminal 1 will use ber 1 within the “chained” assembly ).
Note: Branching terminals can offset a sequence but do
not interfere with the indexing process in given “chains”.
13.1. Conformance Testing
13.1.1. Testing with VFL – (Recommended)
Testing with “light” owing down stream is the simplest way to verify lead continuity as it only requires a dust cap removal on the far end to verify all links are connected.
SAFETY NOTE: Laser driven VFL’s are powerful and
should not be looked a directly to evaluate beam. Use
caution when searching for light with you naked eye and maintain a safe distance. Refer to VFL documentation for safe defused viewing distance.
13.1.1.1. Lead Continuity
From an upstream position like an FDH, place your VFL on the 12th ber* of the lead you are testing.
At the last terminal in the lead, remove the green
HMFOC dust cap and look for red light. If no light, remove any black dust cap and look for red light**. If no light still, the chain is “open”.
* 12th ber continuity testing relies on all bers being spliced or connected prior to the rst terminal.
** Applies to twelfth link in chain
12.4.3.5. Thread the optical port dust cap into the drop cable dust cap as shown below and then tighten both
dust caps nger tight. This ensures that both dust caps will stay clean when not in use.
12.5. Disconnecting the drop cable from the indexing terminal (full size hardened connector housing) adapter port
Danger: Exposure to laser radiation can seriously damage the retina of the eye. Do not look into the ends
of any optical ber. Do not assume the laser power is turned-off or that the ber is disconnected at the other
end.
12.5.1. Unscrew the optical port dust cap from the drop cable dust cap.
12.5.2. Unscrew the drop cable connector coupling nut from the optical port and pull the connector straight out the adapter.
12.5.3. Inspect the optical port dust cap O-ring for
dryness and apply O-ring lubricant (MST-ACC-LUBE1) to the O-ring if dry. Refer to Section 12.6 for the required
procedure.
12.5.4. Thread the optical port dust cap into the optical port and tighten using the 216B key tool.
12.5.5. Inspect the drop cable connector O-rings for
dryness and apply O-ring lubricant (MST-ACC-LUBE1) to each O-ring if dry. Refer to Section 12.6 for the required
procedure.
12.5.6. Thread the drop cable dust cap onto the drop
cable connector coupling nut and tighten until nger tight.
12.6. Applying O-ring lubricant
The O-rings used on the hardened connector and on the optical port dust cap are lubricated when shipped
from the factory to prevent damage during installation. If the O-rings become excessively dry, they may require
additional lubrication to prevent damage. Remove the
O-rings from the connector or dust cap and apply a small amount of lubricant directly to each ring. Then reinstall the O-rings on the connector or dust cap. Apply only the
recommended O-ring lubricant (MST-ACC-LUBE1).
Note: Excessive lubricant on the o-ring may cause contamination of ber endface.

13.1.2.3. Terminal Performance
From an upstream position like an FDH or CO, attach one of the test units to the ber associated with the terminal you are testing.
At the target terminal, connect the other test unit
to each black dust cap port and take readings.
Readings across all ports should be similar.
13.1.3. Testing with an OTDR
13.1.3.1. Lead continuity
From an upstream position like a CO or FDH, attach the OTDR test lead to a ber associated with the last terminal in the lead you are wanting to test. Ideally this would be a ber without a splitter. Attach a reective device like a hybrid patch cord to the same ber at the far end. Conrm reection, move to next lead.
13.1.3.2. Terminal continuity
From an upstream position like a CO or FDH, attach the OTDR test lead to a ber associated with the terminal in the lead you are wanting to test. Ideally this would be a ber without a splitter. Attach a reective device like a hybrid patch cord to the same ber at the far end. Conrm reection, move to next lead.
13.1.3.3. Terminal performance
At the terminal location test all single ber connectors,
record trace(s). Caps sharing same color code should share same characteristics. QR code can be used to access terminal data.
13.1.3.4. Upstream Testing with IOLM
OTDR’s must look upstream to see beyond splitters properly. They must have a dynamic range sufcient to
register multiple cascading events. OTDR’s with IOLM
software are specialized to distinguish splitter type,
mechanical connections, and fusion splices. Use a
known reective event like that of a hybrid SC/APC to SC/UPC launch box to conrm the end-of ber/far end
test point.
Connect a qualied OTDR to any port on the target terminal.
Connect a reective event upstream to the ber associated with the targeted terminal record test readings.
If the rst terminal or “chain” link is known to be good you can use the reverse port on the rst terminal to test continuity for the remainder of the lead as follows:
Connect VFL to reverse port on rst terminal
At the last terminal in the chain, remove the green
HMFOC dust cap and look for red light. If no light, the chain is “open”.
13.1.1.2. Terminal Continuity
Terminal continuity is ber specic.
Attach VFL on target ber.
Look for red light at work order dened end point.
Black dust cap adapters on a given terminal associate to the same single ber up stream.
13.1.2. Testing with a power meter
As with the VFL continuity test, Power Meters (master/ satellite) can be attached in a similar way depending on the architecture of the deployment. Generally this means connecting one test unit at an upstream location like a
hub or CO and the other test unit to the last terminal in the lead being tested. Power Meter testing will require FDH compatible test cords, DLX test cord or Full size
TEST CORD, and possibly an HMFOC test cord or other assembly (FST) if testing via the “multi-ber ports”.
13.1.2.1. Lead Continuity
From an upstream position like an FDH or CO, attach one of the test units to the target ber in the lead you are testing. The target ber should be the ber assigned to the last terminal in the lead you are
testing.
At the last terminal in the lead, connect the other test
unit to any black dust cap DLX/full size hardened port and take readings.
13.1.2.2. Terminal Continuity
From an upstream position like an FDH or CO, attach one of the test units to the ber associated with the terminal you are wanting to test.
At the target terminal, connect the other test unit to
any black dust cap and take readings. If any ports show light, continuity is conrmed.

13.2.4. Cable testing
Injecting red light into the black capped port(s) when the terminal tail HMFOC connector is plugged back into itself via the green capped HMFOC on the body, will allow red light to travel through all ber in the assembly to the red
capped reverse port.
Using an OTDR in this fashion will allow the technician to
see through all ber and connections of the cable assembly in one trace (best results when connected to
the reverse port).
13.2.5. Splitter Performance
Splitter performance can only be tested as part of the terminal assembly. It will be a combination of splitter loss, connector losses (2), and an integral splice. All black dust cap ports on a terminal* shall have similar readings in relation to their shared input ber. See loss tables.
* Index only terminals are excluded as they do not have built in splitters.
13.3. Trouble Shooting
13.3.1. Decision making
Start at the ONT and work upstream.
Conrm adjacent ports on terminals are experiencing same trouble.
Determine status of adjacent terminals
Understand the cable leads and their counts.
Do not disconnect multi ber connectors until you can
physically see its other end or damage.
13.2. Bench Testing
13.2.1. Primary port verication
Injecting red light into black dust cap service ports will
disperse red light in the female (non-pinned) HMFOC connector on the tail of the terminals.
13.2.2. Reverse port verication
Injecting red light into red cap reverse ports will disperse
red light in the male (pinned) HMFOC connector on the
body of the terminal body.
13.2.3. Branching port verication
Injecting red light into the blue cap HMFOC port will
disperse red light in the female (non-pinned) HMFOC connector on the terminal tail.

13.3.2. Loss expectations
Insertion loss and ORL values are recorded and included
with each indexing terminal. Refer to these for “chain” performance expectation.
13.3.3. Cleaning
Refer to section 14.1 HMFOC cleaning
13.4. Restoral
13.4.1. Spare parts
Areas deploying ber indexing terminals should consider stocking a couple spare terminals for tear downs and dig­ups. All four port indexing terminals are interchangeable so stock a length that will cover your needs. Likewise, all eight port indexing terminals are interchangeable. Index only terminals are ber specic but interchangeable in relation to ber count. As an example, if you have a 2f indexing terminal it will interchange with all 2f terminals.
13.4.2. Splicing
Indexing terminals use 12f stranded at drop. No special
splicing requirements. Suggest using GATOR splice closure, FDSC-GATOR-12F-T.

14. Maintenance
The maintenance of the indexing terminal installation
includes cleaning :
14.1. HMFOC cleaning
14.1.1. Inspect the complete multi ber ferrule on the adapter side as well as on the connector side with a low
resolution microscope as specied in IEC 61300-3-35 with oodlight (side illumination). If dirt is detected, follow
cleaning instructions below.
14.1.2. CommScope recommends dry cleaning rst with a tool such as the US CONEC IBC brand cleaning tool - MT Series (PN 15639). Follow the cleaning instruc­tions included with the tool.
14.1.3. To clean the connector on the tail (female, plug, non-pinned) place the blue plug adapter on the end of the
tool, align the keys of the tool and the connector, rotate the thumb wheel clock wise two ‘clicks’.
14.1.4. To clean the adapter on the terminal (male,
jack, pinned) place the red plug adapter on the end of the tool, align the keys of the tool (slot) and the adapter (square notch), rotate the thumb wheel clock wise two ‘clicks’.
14.1.5. If dry cleaning does not produce the desired results, use a small amount of solvent on one or more
Chemtronics ® Covenrty ™ 2.5mm ber optic swabs. A non isopropyl alcohol (IPA) solvent is recommended (such as Chemtronix PX Wash). Using the swabs, re­move contaminates/dirt from the ferrule end face. Always
use a new swab for each connector.
14.1.6. If there is a need to moisten a connector end
face, it must be blown dry with clean compressed air, then dry clean the connector as detailed described in step
14.1.2 untill step 14.1.4.
14.1.7. After cleaning, inspect the multi ber ferrule on adapter and connector side again.
