Telecommunications Backbone and Riser Cables

10.1

At the design stage, plans will be made to route backbone cable from the fiber optic building entrance termination location in the building to the telecommunications room.  Indoor fiber backbone cable will be used and installed in conduit, cable tray, or innerduct in cable hooks in concealed spaces.  The fiber shall be labelled every 300’ along with in each pull box.  Terminations will be made to the fiber optic building entrance location equipment and in the telecommunications room active rack. Fiber optic cable will be tested after the termination is made and before the fiber is put into use. For both fiber optic outdoor and backbone cabling, Corning brand of cable is required, and Corning panels and connectors are required at both the feed location and the terminating location, preferably in the telecommunications rack.  Parts used are as follows.

For indoor single-mode OS2 fiber optic cable:

Fiber-Optic Cables

At the design stage, selection of the inter-building fiber-optic backbone cable(s) shall be made, and plans will be made to route backbone cable from the fiber optic building entrance termination location to each telecommunications room. Indoor fiber riser cable will be used and installed in conduit, cable tray, or inner duct in cable hooks in concealed spaces.

A determination will be made as to what size single-mode fiber optic cable will be used. A minimum of 24 strand SM OS2 fiber will be installed between BDF and TRs.  Fiber optic cable will be terminated and tested before the fiber is put into use. Fiber test results shall be provided to the UIT Communication Wiring group prior to being put into service. Riser cable connections will be made to the fiber optic building entrance location equipment and in the telecommunications room active rack.

For both fiber optic outdoor backbone and riser cabling, Corning brand cable is required. Termination by fusion splice is required. Termination in the telecommunications rack shall be in a fiber panel.

Testing Fiber Optic Cable

Fiber will be tested with a Fluke Versiv fiber optic tester that has been calibrated and certified by Fluke Networks in the previous 24 months. Loss length and OTDR tests will be done for every fiber all test results will be turned over to UIT before any equipment is put on MSU’s network.
