Flexible substrate for routing fibers in an optical transceiver
First Claim
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.

Abstract
An optical transceiver for converting and coupling an information-containing electrical signal with an optical fiber including a housing, an electro-optical subassembly in the housing for converting between an information-containing electrical signal and a modulated optical signal corresponding to the electrical signal from which at least two optical fibers extends; and a flexible substrate for securing each of the optical fibers to prevent tangling in the housing interior and to enable said fibers to bend from a first orientation to a second orientation. An optical fiber receptacle or connector is provided on the housing to couple to an external optical fiber.
