摘要：A fiber optic distribution system provides a frame having several bays forreceiving connector modules, associated jumper organizers, and upper and lower troughsfor conveying jumper fibers between adjacent bays. The jumper organizers areconstructed such that interbay jumpers need not undergo more than two continuousbends of 90°, and further easily store excess jumper slack, such as is required to avoidmodal noise, even when both ends of the jumper are terminated in the same tray orcabinet. Each connector module has a plurality of connector trays pivotally attached to acabinet using a swivel bracket which is located adjacent a gap in the tray sidewall; thisallows placement of the incoming fibers into the tray without the need for threading thefibers through a hole, and also minimizes fiber stress during pivoting movement of thetrays. Front and back plane storage areas are provided for receiving excess slack fromboth incoming and jumper fibers, and a passageway may join these areas to allowcustomized 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 asthey exit the tray. A novel coupling adapter is also provided which flips one end of theinterconnection device upward to allow easier installation of a connector plug.
