Abstract

A fiber management frame having a movable work platform and an interconnection closure including the fiber management frame are provided for supporting and securely retaining various sized optical fiber connection trays and test equipment adjacent the fiber management frame, while also permitting a technician to readily support and retain any one of the trays without damaging the optical connections housed by the trays. The work platform includes a generally planar shelf and a bias member positioned on the shelf opposite a pair of upwardly and inwardly extending first outer flanges. The bias member biases the tray in the direction of the first outer flanges so as to securely retain the tray between the bias member and the first outer flanges. Preferably, the work platform is hingedly mounted to the fiber management frame such that the work platform can be rotated between an operational position and a stowed position.
