Abstract

A high density fiber optic distribution frame includes a frame assembly, one or more left-hand connector module housings mounted on the frame assembly, one or more right-hand connector module housings mounted on the frame assembly and an Interbay Storage Unit (IBU) positioned on the frame assembly medially between the left-hand connector module housings and the right-hand connector module housings. Each connector module housing includes one or more connector modules having one or more adapters for interconnecting optical fibers between connector modules on the distribution frame or on an adjacent distribution frame in a communications network. The distribution frame is compatible with existing fiber optic connector housings, maintains the minimum bend radius of the optical fibers transitioned on the frame between connector modules, and reduces the length of a single length jumper employed on the frame. An alternative embodiment includes an Interbay Fiber Manager (IFM) for routing and storing additional jumpers.
