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.

Abstract: The present disclosure is directed to a keyed optical component assembly that ensures that the same has a proper orientation when press-fit into or otherwise coupled to a complimentary opening of an optical subassembly housing. In an embodiment, the keyed optical component assembly includes a base portion defined by a first end and a second end disposed opposite the first end along a longitudinal axis. A first arcuate region extends from the first end towards the second end and transitions into a tapered region. A second arcuate region extends from the second end towards the first end and also transitions into the tapered region. Therefore, the tapered region extends between the first arcuate region and the second arcuate region, and generally tapers/narrows from the second arcuate region to the first arcuate region. The resulting shape of the base portion may generally be described as an asymmetric tear-drop shape.

Abstract: The present disclosure is generally directed to a component bridge that couples to a feedthrough device to provide additional component mounting surface area within a TOSA housing, and preferably, within a hermetically-sealed TOSA housing. The component bridge includes a body that defines a component mounting surface to couple to electrical components, e.g., one or more filtering capacitors, and a notched portion to provide an accommodation groove. The component bridge includes at least one projection/leg for coupling to a mounting surface of a feedthrough device. The accommodation groove of the component bridge allows for other electrical components, e.g., RF traces, to be patterned/disposed on to the mounting surface and extend at least partially through the accommodation groove while remaining electrically isolated from the same. Accordingly, the component bridge further increases available component mounting surface area for existing feedthrough devices without necessity of re-design and/or modification.

Abstract: The present disclosure is generally directed to a multi-channel TOSA arrangement with a housing that utilizes a feedthrough device with at least one integrated mounting surface to reduce the overall dimensions of the housing. The housing includes a plurality of sidewalls that define a hermetically-sealed cavity therebetween. The feedthrough device includes a first end disposed in the hermetically-sealed cavity of the housing and a second end extending from the cavity away from the housing. The feedthrough device provides the at least one integrated mounting surface proximate the first end within the hermetically-sealed cavity. At least a first laser diode driver (LDD) chip mounts to the at least one integrated mounting surface of the feedthrough device. A plurality of laser arrangements are also disposed in the hermetically-sealed cavity proximate the first LDD chip and mount to, for instance, a LD submount supported by a thermoelectric cooler.

Abstract: The present disclosure is generally directed to an on-board ROSA arrangement where a fiber receptacle element, optical components such as optical de-multiplexer (e.g., an arrayed waveguide grating (AWG)), turning mirror, photodiodes and light receiving chip are mounted to a common substrate. The fiber receptacle element includes a body that defines a slot to at least partially receive an end of the substrate and mount thereto. The body of the fiber receptacle further includes an aperture that extends through the body to receive an optical fiber and/or associated connector and align the same with ROSA components mounted on a surface of the substrate. The fiber receptacle body may be solid, e.g., formed from a single, monolithic piece of material, and may be manufactured from metal, plastic or other suitably rigid material.

Abstract: A transceiver module having a partitioned housing, e.g., a bifurcated or multi-segment housing, is disclosed that allows coupling and alignment of a TOSA arrangement and ROSA arrangement in separate respective portions in order to minimize or otherwise reduce component damage and rework iterations during manufacturing and repair. Technicians may thus perform at least partial assembly and testing of each optical subassembly arrangement in parallel and in relative isolation without necessarily interrupting and/or waiting on completion of the other. In a general sense, each separate portion of the partitioned housing provides a dedicated workspace of about equal dimension for coupling of subassembly components. Each separate portion may lie flat on a tabletop, for instance, which may further simplify manufacturing processes and provide a wide-range of acceptance angles for performing soldering, welding, insertion and coupling of components, visual inspection, fiber routing, and so on.

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.
