Claim Text:
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; 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; a cable of a predefined length extended from the transceiver housed in the second enclosure to the multi-fiber cable of the first enclosure, wherein the passive optical components are fixed to a substrate housed in the first enclosure, the passive optical components and the substrate are epoxy sealed, soldered or laser welded in a unit so that moisture would not enter into the unit or degrade performance of each of the passive optical components, and wherein the first enclosure is a ruggidized cage to accommodate the unit with two transition areas for the plurality of fibers and the at least two fibers that are provided in the first enclosure to isolate the plurality of fibers and the at least two fibers from experiencing undesired forces.
