ABSTRACT:
An optical transceiver module for use in optical communications networks is disclosed. The transceiver features a simplified optical subassembly structure that facilitates the alignment and calibration of active optical components located thereon. The transceiver includes a shell that contains a transceiver printed circuit board and a transmitter/receiver optical subassembly (“TROSA”) connected to the printed circuit board via a TROSA connector. The TROSA includes a singular substrate on which a laser for producing optical signals and a photodetector for receiving optical signals are disposed. The laser and photodetector are precisely positioned on the TROSA substrate to have a specified spacing therebetween. So positioned, the laser and photodetector can be aligned with conduits of a sleeve assembly in a single alignment operation, thereby simplifying calibration of the transceiver module. The present transceiver eliminates the use of multiple substrates separately supporting the laser and the photodetector, thus also eliminating related alignment challenges.
