1. About this installation instruction

This installation instruction describes the installation of the ber indexing terminal of both housings, the DLX connector housing and the full size hardened connector housing, and their different applications: the standard indexing terminal with splitter (1:4 or 1:8), the indexing only terminal, the branch terminal and the multi-use terminal.

The instruction will explain how to handle the stubbed cable, how to mount the terminal in different situations (hand hole, pedestal, pole and aerial), how to connect and maintain the different connector types (DLX, full size hardened

connector and HMFOC) and how to test the installed chain of terminals.

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).

Image below shows the available ports and color code of

the adapters of this terminal conguration:

Both housings are designed to meet aerial and pedestal conditions. For hand-hole application, the housings are designed to meet the conditions for hand-holes located up to 3 meters (10 feet) under ground.

5.2. Congurations

To build the network, each housing type is available in 4 congurations:

• Standard indexing terminal with 1:4 splitter

• Standard indexing terminal with 1:8 splitter

• Indexing only

• Branch terminal

5.2.1. Color code (ports)

To ensure correct installation, the terminal ports are colorcoded:

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.

If there are more subscribers (homes) around the

indexing terminal to feed, the terminal can have a 1:8

splitter instead of a 1:4 as described in section 5.2.2. 8 homes can be fed (passed) from this terminal.

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.

5.5.4. Cleaning kit FHD-ACC-CLNKIT1

To clean the drop ports adapters and connectors (both full

size hardened and DLX), a cleaning kit can be ordered. How to use this is explained in chapter 14 maintenance.
