Abstract
Techniques for reducing optical fiber bending loss in an optical transceiver are disclosed. In an embodiment, a small form-factor (SFF) optical transceiver housing includes a demultiplexer device, such as an arrayed waveguide grating (AWG) device, having a longitudinal center line that is offset laterally by a distance Doffset from the longitudinal center line of the SFF optical transceiver housing. The lateral offset distance Doffset may advantageously enable an intermediate optical fiber coupling the demultiplexer with an optical coupling receptacle, such as an LC connector, to be routed within the SFF optical transceiver housing in a manner that avoids introducing bends that are less than a minimum bending radius associated with the intermediate optical fiber cable. Thus some embodiments of the present disclosure enable greater tolerance when routing an intermediate optical fiber within housings that would otherwise introduce bending loss by virtue of their constrained dimensions.
