WDM MUX/DEMUX ON CABLE AND METHODS OF MAKING THE SAME

摘要

Techniques for WDM Mux/DeMux on cable and methods of making the same are described According to one aspect of the present application, a unit designed to provide multiplexing or demultiplexing (Mux/Demux) functions is implemented on cable. In other words, the Mux/Demux unit is coupled by a multi-fiber cable to a system (e.g., a system rack for router or switch that has multiple pluggable transceiver slots).

主权项

1. An optical device comprising:
a first enclosure, including a box housing passive optical components to provide multiplexing or demultiplexing (Mux/Demux) functions, having first and second ends disposed on two opposite ends of the first enclosure, wherein a multi-fiber cable secured on the first end is coupled to a plurality of fibers connected respectively to the passive optical components, and a duplex fiber cable secured on the second end includes at least two fibers, one from an input to the Mux/Demux functions and the other from an output of the Mux/Demux functions, wherein the duplex fiber cable is extended from the second end of the first enclosure to a duplex cable connector; and a second enclosure in a form factor to be received in one of multiple pluggable transceiver slots in a system rack, the second enclosure including a transceiver; wherein the first enclosure accommodates a first transition area at the first end of the first enclosure for the plurality of fibers and a second transition area at the second end of the first enclosure for the at least two fibers to isolate the plurality of fibers and the at least two fibers from experiencing undesired forces.
