Abstract
Techniques for flexible coupling between an optical coupling receptacle/port of an optical transceiver housing and optical components within the same are disposed. In an embodiment, an optical transceiver housing includes an intermediate fiber with a first end optically coupled to an optical coupling port and a second end optically coupled to a multiplexer/de-multiplexer device, e.g., an arrayed waveguide grating (AWG) device, PLC splitter, and so on. The intermediate fiber may be routed in the transceiver housing in a manner that and the radius of the bends may be optimized to reduce fiber bending losses. The techniques herein are equally applicable to both ROSA and TOSA modules and may be utilized to achieve flexible coupling for multi-channel transceiver devices.
