Abstract: A cable management device that hangs downward an overhead cable conveyance, such as a ladder rack or cable tray. The cable management device includes an enclosure chamber and a patch board. Spare runs of cable can be stored, out of sight and out of the way, in the enclosure chamber. the patch board allows cable connections to be made at the juncture where a cable “pays off” of its overhead conveyance, before heading downwards to a component rack extending upwards from the floor of the data center. Also, a flipper wiring path trunk assembly, for a set of 12 optical signals, with LC duplex modules and LC connectors.
