Each cassette normally accommodates 24 splices. If all feeder and distribution fiber requires splicing, a total of 18 cassettes are
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 compart-
ment splitters.
• The distribution adapters are located on 72-port modules (Models MDC-P72N). Fan-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.
