LIGHTGUIDE DISTRIBUTING UNIT

摘要

LIGHTGUIDE DISTRIBUTING UNIT A multishelf main distributing frame for lightguide fibers is provided in which each shelf includes a pair of spaced plates for receiving cable fibers from the rear portion of the shelf, receiving cross-connect jumper fibers from the front portion thereof, and having one or more removable connector panels for terminating lightguide fibers at opposite sides thereof. The panels are recessed from the front edges of the shelf to assure room for a predetermined minimum bending radius for jumper fibers connected to the front of the panels. Once such panels are installed, they cooperate with the shelf plate members and with a windowed cable channel at the rear of the shelf for protecting relatively lightly sheathed individual fibers of cables passed through the channel into the shelf region. A hinged closure is provided at the front of each shelf for protecting cross-connect jumper fibers of that shelf without subjecting those fibers to possible mechanical damage when the closure is closed.
