OSP Distribution Cable Configuration
Each distribution cable has a fiber count that is a multiple of 72. From 1 to 12 distribution cables
may be present depending on the number of distribution panels ordered and the cable fiber
count. Within the cabinet, each distribution cable is secured with a pair of clamps. Beyond the
clamps, the outer sheath of the cable is removed to expose the optical fiber subunits. Each
subunit is fanned out into 12 individual fibers, each of which is terminated with a connector.
The fiber subunits are routed to the back of the distribution panels. Each fiber connector is
connected to a specified bulkhead adapter at the rear of the panel. Depending on the option
ordered, the distribution panels may be equipped with either
UPC/SC or APC/SC
adapters
.
A
diagram of the distribution cable configuration is shown in
. Distribution cables with
72, 144, 216, 288, 360, or 432 fibers are available.
Designation labels are provided on the cabinet doors for recording subscriber information for
each distribution panel port. The labels indicate the fiber number and cable number associated
with each fiber port. The subunits are numbered and the individual fibers are color-coded for
identification. Always perform a light test before splicing to determine the port location for each
fiber.

Note:
The maximum fiber count for stranded-type fiber optic cables is 288 fibers per
cable. Ribbon-type cables may have a maximum fiber count of 432 fibers per cable.
