Cabinet

Base

Telect’s MDC-CB is an indoor/outdoor fiber telecommunication distribution cabinet. The cabinet h ouses T elect’s bulkhead-style Patch Modules to handle optical signal distributio n between a CO and the network edge. A single MDC-CB cabinet with up to six Telect Patch Modules can provide distribution service to 432 homes, offices and/or nodes.

The weather-tight, heavy-gauge, light-weight aluminum cabinet is almond with two lockable doors — both doors have wind stays. OSP feeder and distribution cable enter through weather-tight cable clamps at the bottom of the rear compartment:

Illustrations that follow depict open-door views of MDC-CB cabinets with and without in-cabinet splicing.

Along with the cabinet, Telect includes a footprint template which is also the isolation pad, two cable entrance clamps for two feeder cables between mm) and 1 ing the door latches. The MDC-CB includes a 6-in. base. A 12-in. Telect base (Model MDC-R12) is optional.

Physically, the only difference between MDC-CB cabinets with or without splicing is the splice box on the rear door. Feeder and distribution cabling for the two is, however, quite different.

Cabling without in-cabinet splicing involves an aerial or below-ground splice box for splicing the distribution and feeder cables to connectorized cabinet cabling.

• At the cabinet, the OSP distribution cable is clamped at the floor of the rear compartment and then routed along the cabinet’s compartment partition. The connectorized 250 µm strands break out here into subunits/buffers and then connected to one of the six possible, 72-channel Patch Modules. Each patch module contains SC/APC adapters to interface the distribution fiber in the rear compartment to the cross connections in the front compartment.

• Feeder cable is anchored along the rear side wall where 900 µm fiber breaks out into subunits/buffers and routed to 16 SC/APC interface adapters near the top of the cabinet.

Each SC/APC adapter at the top of the cabinet serves to feed the fiber signal to a blue jumper in the front compartment, shown in the preceding illustration. The blue jumper is routed down through the right portion of t he front compartment, then around a couple of spools and an arc. The two spools at the bottom route the blue fiber to a Telect Splitter Module.

Up to 18, 1x4, 1x8, 1x16, or 1x32 Telect Splitter Modules can be installed in the splitter bulkhead at the bottom of the front compartment. Each splitter module consists of the splitter, one blue “input” jumper, and either 4, 8, 16, or 32 yellow “output” jumpers. All are 2 mm jumpers, 2.1 m in length.

Splitter module installation and all of the distribution changes occur in this front compartment:

• Unassigned jumpers are routed via spools and arcs to a parking station for later subscriber assignment.

• Assigned jumpers are routed via the spools and arcs to the front of the SC/APC adapters in the front of the patch modules for cross connection to the distribution fiber connected to the rear of the patch modules.

The following illustration shows a deployed cabinet along with a partially cabled rear compartment.

MDC-CB WITH REAR COMPARTMENT IN-CABINET SPLICING

The distribution and feeder OSP enter the cabinet at the floor of the rear compartment. The installer clamps the cable and breaks out the fiber into 3-mm, radius-control (limited bend) loose tubing. The installer anchors feeder and distribution tubes along the cabinet’s side wall and rear door.The tubes are guided to the top of the optional splice box located on the door.

The optional in-cabinet Telect Splice Box (Model MDC-SPLC) holds three pods of splice cassettes surrounded by a runway for the loose tubing.

needed to accommodate all 432 subscribers. For the distribution splices, each pod would hold 6 splice cassettes plus one additional cassette on one of the pods for up to 16 feeder splices.

Feeder and distribution strands are spliced to connectorized fiber protected by 3-mm, radius control loose tubing. All tubing from the cassettes to the feeder interface and patch modules cross the door hinge near the top of the cabinet. The tubing is anchored along the compartment partition and guided to SC/APC feeder or distribution adapters:

• The feeder interface near the top, rear-side of the cabinet contains 16 adapters to pass feeder signals to the front compartment splitters.

• The distribution adapters are located on 72-port modules (Models MDC-P72N). Fa n-out blocks on the Patch Modules are used to accommodate the transition from 3-mm, multi-fiber loose tubing to 900 µm transparent tubes, one for each of the 72 fibers. A total of 6 Patch Modules accommodate the 432 possible subscribers. The SC/APC adapters pass signals to the front compartment for assignment patching.

FRONT COMPARTMENT CROSS CONNECTIONS

Front compartment feeder and cross-connect cabling is the same for cabinets with or without in-cabinet splicing. Each SC/APC adapter at the top of the cabinet serves to feed the fiber signal to a blue jumper in the front compartment. The blue

jumper is routed down through the right portion of the front compartment, then around a couple of spools and an arc. The two spools at the bottom route the blue fiber to a Telect Splitter Module.

NOTE: Dimensions are in in. (mm)

Please note the following recommendations:

• Telect recommends that the cabinet be mounted with either the 6-in.-high base or optional 12-in.-high base (Models MDCR12) or a suitable vault, along with the isolation pad included with the cabinet. (See “Standard Accessories” Page 7-1.) If the cabinet is mounted to a concrete pad without a pedestal or vault, the stub-up conduit for the cables must be positioned accurately and must be either absolutely flush with or countersunk below the top of the pad.

• For a cabinet with a Telect base, the stub-up conduit should not rise above a concrete pad more than about 3 in. (~75 mm) for a 6-in.-high base and about 6 in. (~150 mm) for a 12-in .-high base. See the following illustration.

• Telect recommends running cables in 4-in. stub-up conduit. Normally, two 4-in. conduits are necessary: one for the feeder cable(s) and at least one for the distribution cable(s), as shown in the illustration that follows. Prefer to run feeder cable as close as possible to the grounding bar — regardless if feeder is armored or unarmored.

• Don’t forget to make room for growth. Add additional 4-in. conduit and cap off the end(s) at the edge of or beyond the pad.

• Telect recommends anchors at all four corners. Upper end of anchor bolts must extend between 1¼ in. and 1½ in. above top of pad, grating, or platform.

• For outdoor deployment, Telect recommends that, in addition to the isolation pad provided with the cabinet, that the customer plan for and provide a suitable water-tight gasket between the bottom of the cabinet and the pad. Use the preceding illustration to mark and cut a rectangular hole for cable entrance.

vice Department. Use the original, undamaged container if you are instructed to return a panel to Telect. If a shipping container is damaged, keep it for the carrier’s inspection. Notify the carrier and call Telect’s Customer Service Depart-

ment at 1-800-551-4567 or 1-509-926-6000

INSTALLATION PROCEDURE

Please read these instructions carefully before beginning installation. If you need assistance call Technical Support at 888-821-4856 (domestic calls), or 509-921-6161 (Option 2), or eMAIL us at [email protected]

1. Inspect equipment after unpacking and compare it to the packing list. Immediately report any shipping damage, defects, or missing parts to

Telect at 1-800-551-4567. Keep all documentation that comes with your shipment.

2. Remove lifting rings at top of cabinet and then resecure as shown on the right.

3. Before moving cabinet is ready: namely,

• If installation includes a vault, make sure vault-to-cabinet adapter is

in place.

, make sure the pad, grating, vault, or other support

• If using Telect’s seismic anchor kit (Model MDC-CBAK), install anchors

at each of the four anchor locations.

b. Clean out holes using a shop vacuum, compressed air, or blow-out bulb.

Clean away debris.

c. Place round washer on rod and then thread torque nut onto the rod. The

washer should touch the top of the metal sleeve.

d. Insert anchor assembly (without the square washer) into hole. Tap anchor

rod down with a hammer until washer touches the concrete.

e. Pre-torque anchoring nuts to approximately 30 ft-lb (~40 N•m) using a ¾ in.

(19 mm) socket or box wrench. Do not overtighten. Over-tightening will cause the torque nut to prematurely

shear off from the plastic-encased holding nut. f. Remove torque nut and washer, leaving anchor and stud in place. g. For exterior installation on a concrete pad, place a water-tight gasket with

cutouts for conduit and anchors on top of pre-installed pad.

AVERTISSMENT ! Les câbles à fibres transmettent un rayon laser ou une lumière infrarouge invisible. Pour éviter toute lésion occulaire ou cécité, ne regardez jamais directement dans les fibres ou dans les connecteurs.

Fiber installation without in-cabinet splicing involves installing connectorized OSP feeder cables to the floor of the cabinet’s rear compartment and then terminating those connectors at compartment interface adapters near the top of the cabinet. The connectorized distribution cabling is pre-terminated to the patch module assemblies at the factory. These optional patch module assemblies are secured to the cabinet partition. The distribution cables, like the feeder cables, are secured to the bottom floor of the rear compartment.

After installing all feeder and distribution cables at the cabinet end, the opposite ends are then spliced to OSP cables located in a splice enclosure.

FEEDER CABLE INSTALLATION

The cabinet accommodates up to 16 strands of connectorized OSP feeder cable. Telect supplies two cable clamps that accommodate cables between

3

/8 in. (9.6 mm) and 11/5 in. (30.5 mm) in diameter. Each clamp, shown on

the right, uses several layers of gasket or bushing leaves to hold the cable fast between the two halves of the clamp.

OSP cable can be dry or wet, armored or unarmored. T o connect to adapters in the cabinet the cable needs SC/APC connectors.

To install a feeder cable, proceed as follows:

1. Open rear door.

2. Remove cable entrance dock at bottom of cabinet by removing six sets of nuts and washers shown in the following illustrations.

The cable entrance dock contains eight slots with slide-out cover plates. Each slots can accommodate two cable clamps for either feeder or distribution cable.

3. Slide out cover plate over feeder stub up. If all feeder cable enters through the stub up closest to the feeder tie-down wall, choose the slot nearest the tie-down wall. If a

second feeder cable is being installed, prefer to locate both in the same slot.

closure. Before splicing, use cable ties “temporarily“ to hold the cable end(s) in the cabinet to convenient lance(s) along the feeder tie-down wall. Tie it down temporarily so that the SC/APC connectors will reach the feeder adapters at the top of the rear compartment.

6. Wait until all feeder cable is connected and secured in the cabinet before external splicing.

7. Connect SC/APC connectors on all feeder fibers to feeder adapters.

8. Measure diameter of cable(s) and remove and discard that much from the interior of the cable clamp’s leaf bundle equal to the diameter of the cable(s). The remaining leaves will be used between the clamp halves and the cable.

9. Nearby the cable entrance, where the cable entrance dock had been, loosely

secure the left bundle(s) and clamp halves to the cable(s), as shown in the illustration at the start of this procedure.

10. Place cable entrance dock at bottom of cabinet and slip on cable clamps, as shown in the illustration on the following page.

If you have only one feeder cable to install, you must use the other cable clamp to fill out the slot.

11. Hold down or temporarily fasten dock to cabinet, and then arrange feeder cable(s) and tubing along the feeder tie-down wall. Use cable ties generously to fasten cable and tubing to the wall.

Don’t use cable ties closer than ~1 ft (~300 mm) from the floor until all feeder and distribution cables are installed. You’ll need some wiggle room for removing/re-installing the cable entrance dock.

12. Remove the entrance dock again and securely fasten the cable clamps to the cable. You will fasten the entrance dock to the cabinet after the distribution cable is installed in the next subsection.

A cabinet with feeder cable installed is shown on the following page.

13. Splice the other end of the feeder cable.

Telect offers a standard length of cable to fit most applications: 100 ft (30.48 m), measured from a fan-out block attached to the Patch Module to the stub end. (Custom lengths available on request.) Telect breaks out short lengths of subunits for the shortest probable distance from the cable clamp to the Patch Module. The subunit breakout can be increased on site. Telect includes the cable clamp for securing the cable to the bottom of the cabinet and a short length of heat-shrink tubing for covering the breakout.

Page 3-5

The cable clamp, shown on Page 3-1, is the same type used to secure distribution cable. One cable clamps is provided. An additional cable clamp may be required to fill out the two-position entrance slot. (See “Standard Accessories” on Page 7-1.)

The fan-out block allows transition from the 250 µm fiber in subunits to individual connectorized fiber strands in 900 µm transparent tubes. Telect terminates the connector at adapter ports at the rear of the patch module.

To install a Patch Module with distribution cable, proceed as follows:

1. Open rear door.

2. Remove cable entrance dock at bottom of the cabinet, shown on Page 3-2.

3. Slide-out cover plate over distribution stub up(s). Patch Modules will be installed from the top position (Patch Module 1) to the bottom (Patch Module 6). Unless otherwise direct-

ed by operating company guidelines, prefer to start with the first distribution stub-up farthest from the patch module rack. Determine the length of the subunit breakout between the fan-out blocks on the edge of the patch module and the sheathed ca-

ble. The end of the sheathed cable will be either clamped and tied down on the distribution tie-down wall or

at the cable clamp

on the cable entrance dock.

NOTE

Telect only breaks out about 7 in. (~175 mm) of subunit. Th is would be for the shortest b reakout from a cable clamp near the center of the cable entrance dock to Patch Module 6. The longest bre akout would be about 64 in (~160 0 mm) betwe en a cable clamp near the left wall (viewed from the front of the cabinet) to Patch Module 1.

All cables entering the cabinet directly below the patch module rack need to be broken ou t at the cabl e cl amp. The cable is not flexible enough to manipulate it below the rack and around to the distri bution tie-down wa ll. Conversely, all cables entering the cabinet directly below the distribution tie down wall should be extend ed up the tie-dow n wall and tied down just below a co nvenient breakout point. (Refer to the illustration on Page 1-4.)

4. Breakout subunits, heat shrink breakout, and then feed the opposite end of the cable into the distribution stub-up condu it.

5. Move the cable clamp down to approximately where the cable will enter the bottom of the cabinet.

NOTE

Before connecting, splicing, storing, or parking distribution pigtails at the home, office, or node, install the Patch Module in the cabinet, as detailed in the following procedure. Refer to the following illustration.

6. If necessary, provide temporary strain relief while handling and installing Patch Module by, for example, loosely tying down the cable at a convenient lance along a tie-down wall.

7. Swing out hinged bulkhead from patch module’s anchor plate so that bulkhead fits through rack into front compartment. Then, secure anchor plate to partition wall using three acorn nuts provided.

8. Secure cable and subunit to distribution cable tie-down wall. Use plenty of cable ties. Don’t use cable ties closer than about 1 ft (~300 mm) from the floor of the cabinet until all feeder and distribution cables are in-

stalled. You’ll need some wiggle room for re-installing the cable entrance dock.

9. At bottom of cabinet, adjust position of cable clamp in relationship to the cable entrance dock. Don’t secure the entrance dock until all scheduled distribution cables and Patch Modules are installed.

Fiber installation with on-board cabinet splicing involves installing Telect’s optional splice box and distribution patch modules in the rear compartment of the MDC-CB. The feeder and distribution cables are secured to the floor of the rear compartment. The installer routes the fiber breakout to the splice box where it’s spliced to connectorized fiber. In turn, connectorized feeder and distribution fiber is routed and then terminated to the compartment interface adapters and distribution patch modules.

SPLICE BOX INSTALLATION

Install the Model MDC-SPLC Splice Box on the inside of the rear door using the hardware provided, as shown in the following illustration. (See “Accessories” Page 7-3.)

PATCH MODULE INSTALLATION

The Model MDC-P72N Patch Module is installed from and secured to the rear compartment. (See “Accessories” Page 7-3.) To install, swing out the hinged bulkhead from the patch module’s anchor plate so that the bulkhead fits through rack and into front

3. Slide out cover plate over feeder stub up.

4. Fish feeder cable into cabinet and then remove at least 15 ft (~5 m) of sheathing from the cabinet end.

NOTE

15 ft allows the feeder fiber to reach the furthest splice cassette. Break out more buffer/subunit if you intend to splice anywhere but at ground level at the open rear door. Add multiples of 8½ ft (~2.5 m) when adding to this length if the splicing is done, for example, in a vehicle. The multiple represents the perimeter around the splice box for storing the excess length of tubing.

Routing Feeder & Distribution Loose Tubing (Overall View)

How many cassettes to place on each holder depends on how many feeder and distribution fiber pairs require splicing. If you intend to accommodate 16 (max.) signals from the CO and up to 432 (max.) from the distribution, you need a total of 19 cassettes: one for the feeders and 18 for the distribution. It’s wisest to arrange cassettes more or less evenly among the holde rs. It’s also wisest to add all intended cassettes to the stack before running loose tubing and splicing any of the cassettes.

Normally, each cassette holds up to 24 splices. If desired, up to 48 splices will fit each cassette in two layers of 24 — 24 lower and 24 upper. Two layers makes for a crowd cassette, howeve r, but lessens the number of cassettes overall.

16. After completing a stack of cassettes (a cassette pod), check the length of loose tubing required to reach the cassette. The following illustrations show the shortest and longest required paths for tubing.

The distance between the feeder cable breakout at the cable entrance and the cassette entrance will vary from 5 to 8 ft (~1.5 to ~2.5 m) depending on the starting and ending points in the cabinet and on the door. Check the distance and add in multiples of 8½ ft (~2.5 m), if desired, and then carefully cut off the excess tubing, being mindful of the fiber strands within. DON’T CUT THROUGH THE FIBER because you will need an additional 3 ft (~1 m) beyond that point for the unprotected strands which will be in the cassette. So, 3 ft (~1 m) passed the end of the loose tubing, cut away the excess fiber.

23. Continue with “Distribution Cable Installation” in the next section before installing the pod on the door and before securing tubing to the cabinet and door. Do not mix feeder and distribution splices in the same cassette.

DISTRIBUTION CABLE INSTALLATION

The cabinet accommodates up to 432 strands of OSP distribution cable. Telect does not include cable clamps for the distribution cable. The cable clamps are the same

type used for the feeder cables. See “Accessories” on Page 7-2. Like the feeder cable, OSP distribution cable can be dry or wet, armored or unarmored. To connect to adapters in the patch module,

the incoming distribution fiber needs to be spliced to fiber strands with SC/APC connectors. The breakout, splicing, and routing of distribution is similar to that of the feeder. In brief,

1. As before, remove at least 15 ft (~2.5 m) of sheathing from the distribution cable entering the cabinet. More, if desired, in 8½ ft (~2.5 m) increments. Also remove the buffer/subunit tube covering the fiber and slip on 3-mm, radius control loose tubing.

2. Heat shrink tubing to cable at entrance dock and then attach a cable clamp

3. Check the length of loose tubing required for the run between the cassette and the fan-out block on the patch module. The distance will vary from 6¾ to 9¾ ft (~2 to 3 m) depending on the starting point on the door and the location of the patch

module. Check the distance and add in multiples of 8½ ft (~2.5 m), if desired, to determine tubing length. For the fiber, you will need this length plus an additional 4 ft (~1.25 m) beyond that point for the unprotected strands which will be in the cassette and for the fiber from the entrance of the fan-out block to the adapter on the patch module.

4. For each loose tube of 12 fibers, you will need a fan-out block to adapt the fiber in one loose tube to individual fibers in a 900 µm loose tubes.

6 Fan-Out Blocks Per Patch Module

a. The furcation block has about 1.5 m (~5 ft) of transparent tubing for 900 µm fi-

bers. Cut the transparent tubing back to 11½ in.(~300 mm).

b. Slip the fibers through the furcation block and transparent tubes and move the

ends of the transparent tubes up to the SC/APC connectors. c. Next, slip on the heat-shrink tube supplie d with the fan-out kit d. Place the furcation block onto the bottom cover. e. Snap on the top cover. f. Slide up the heat-shrink tube against the block and heat shrink.

5. Secure ends of both distribution tubes at opposite entrances to the cassette, route fiber throughout cassette (Page 4-9), trim excess, slip on splice sleeve, and splice.

6. Record terminations on designation label included with cassette.

7. Finish all splices in a cassette before moving to the next.

8. Continue with the remainder of the fibers from the distribution cable — splicing them to connectorized fibers — before moving to the next cable.

After every 72 fibers (6 fan-out blocks), connect ends of fiber into adapters on the patch module, shown in the following illustration. Use the bracket provided on the patch module to secure the fan-out blocks to the patch module chassis.

9. Complete all cassettes in a pod before mounting the pod to the rear door and before routing the loose tubing.

ROUTING FEEDER & DISTRIBUTION LOOSE TUBING

When completed and before moving to the next cassette pod,

1. Install completed cassette pod on the rear door.

2. Route all loose tubing as planned and use cable ties liberally to secure tubing to lances on door and in cabinet.

3. After all feeder and distribution cabling and loose tubing has been installed, spliced, and routed, re-insert cable entrance dock, tilt it up as shown in the following illustration, and then slip the feeder and distribution cable clamps into the slots. Use extra clamps to fill out the slots containing only one cable.

4. Pivot the dock to the floor of the cabinet and re-install the chock bar. Push the chock bar against the cable clamps.

5. Secure the chock bar and close the rear door.

After installing all feeder and distribution cabling in the rear compartment, close the rear compartment. All subscriber changes are done in the front compartment. First, however, the high-intensity feeder signals needs to be split before cross connecting to the distribution.

Telect Splitter Modules are installed, interconnected to the incoming feeder fiber, and cross connected to distribution fiber in the front compartment. After installing OSP cable, the rear compartment need not be re-opened.

Telect manufactures four Splitter Module configurations for this cabinet: 1 x 4, 1 x 8, 1 x 16, and 1 x 32. To install a Splitter Module, proceed as follows:

1. Start at Splitter Position 18 on the right bottom of front compartment.

2. As shown in the illustration on the right, push in the two plunger-style latches to secure the module.

The splitter module has one blue 2-mm jumper for the feed-in and 4, 8, 16, or 32 yellow 2-mm jumpers for the distribution. All splitter jumpers are 2.1 m in length.

3. Route the blue jumper to the first feeder adapter on the left compartment, as shown in the illustration on the right.

Going from right most splitter module to left most feeder adapter guarantees that the blue jumpers from all splitter modules will neatly fit the same pathway around the routing arcs and spools in the right half of the compartment. Prefer to route the blue jumpers as shown in the following illustration, that is, around the bottom, right most spool, up to the nearest arc, down around the bottom most spool to the left of the other, and on up to the feeder bulkhead.

and insert module in splitter bulkhead near

at the top of the front

, route the cables to the right, around the right most spool at the bot-
