An optical networking circuit pack is described. The circuit pack houses a plurality of pluggable electronic modules and includes an enclosure panel, a plurality of module identifiers, and a fiber management assembly. The enclosure panel has at least two collinear openings to receive electronic modules. The module identifiers reside on the enclosure panel and are proximate to a respective opening. Each module identifier is oriented at an angle with respect to an edge of the enclosure panel to facilitate association of pluggable electronic module with the respective opening regardless of whether the circuit pack is oriented in a horizontal position or a vertical position. The fiber management assembly is disposed at an end of the circuit pack to facilitate routing of optical fibers.

Optical networking circuit pack

A circuit pack handling system, comprising a handle assembly storage pocket formed in the sidewall of a circuit pack and a carrying handle assembly hinge-mounted within the pocket and adapted to retract substantially within the storage pocket. In a preferred embodiment, the system further comprises a handle locking sub-assembly affixed within the backplane end of the storage pocket between the inner wall of the pocket and the inner leg of the handle assembly to lock the handle assembly into the deployed position. In another preferred embodiment, the system further comprises a coil spring fitted at the gripping member hinge-joint of at least one of the legs so as to spring load the handle assembly whereby the handle assembly automatically flips out from the stored position inside the storage pocket to the deployed position as the circuit pack is pulled away from the shelf frame.
