1. An optical transceiver module for converting between (i) an information-containing electrical signal and (ii) a modulated optical signal transported over an at least one optical fiber in the transceiver module comprising:

  • at least one optical fiber coiled over at least a portion of its length;

    a support disposed in the module;

    a flexible substrate for securing said optical fiber to said support to enable said fiber to bend from a first direction to a second opposite direction inside said module and wherein the optical fiber provides a continuous optical path between the first direction and second opposite direction; and

    an optical multiplexer mounted on said flexible substrate for receiving first and second optical fibers and multiplexing the respective optical signals on said optical fibers into a single multi-wavelength beam onto a single third optical fiber wherein said optical multiplexer is a fused biconic tapered coupler.
