Abstract

A fiber optic distribution system provides a frame having several bays for receiving connector modules, associated jumper organizers, and upper and lower troughs for conveying jumper fibers between adjacent bays. The jumper organizers are constructed such that interbay jumpers need not undergo more than two continuous bends of 90.degree., and further easily store excess jumper slack, such as is required to avoid modal noise, even when both ends of the jumper are terminated in the same tray or cabinet. Each connector module has a plurality of connector trays pivotally attached to a cabinet using a swivel bracket which is located adjacent a gap in the tray sidewall; this allows placement of the incoming fibers into the tray without the need for threading the fibers through a hole, and also minimizes fiber stress during pivoting movement of the trays. Front and back plane storage areas are provided for receiving excess slack from both incoming and jumper fibers, and a passageway may join these areas to allow customized fiber circuit paths on the tray. Boot biasing ribs are provided on the tray, along with radius limiting ribs, to maintain a proper bend radius of the jumper fibers as they exit the tray. A novel coupling adapter is also provided which flips one end of the interconnection device upward to allow easier installation of a connector plug.
