Abstract: An optical transceiver module is disclosed having a housing that includes at least a first housing portion and a second housing portion, each of the first and second housing portions including a base portion having at least one sidewall extending therefrom that defines a compartment. The first housing portion is configured to couple to the second housing portion to form a cavity therebetween. A transmitter optical subassembly (TOSA) arrangement coupled to the base portion of the first housing portion and is electrically coupled to a first flexible printed circuit (FPC). A receiver optical subassembly (ROSA) arrangement is coupled to the base portion of the second housing portion and is electrically coupled to a second FPC. A first shield coupled to at least one of the first housing portion or the second housing portion to reduce electromagnetic interference between the TOSA arrangement and the ROSA arrangement.

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: A multi-channel optical transmitter or transceiver uses a reversed planar lightwave circuit (PLC) splitter as an optical multiplexer to combine optical signals at different channel wavelengths into a multiplexed optical signal. The reversed PLC splitter includes splitter output ports that are used as the mux input ports and a splitter input port that is used as the mux output port. The mux input ports may be optically coupled to respective transmitter optical subassembly (TOSA) modules with or without optical fibers. The PLC splitter includes wavelength independent branched waveguides that combine the optical signals received on the mux input ports into the multiplexed optical signal on the mux output port.
