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.

Abstract: An optical module has port housing comprised of a material that does not substantially shield EMI, such as an optical plastic. The port housings have a receiving ferrule disposed in an aperture of an electrically conductive shell. The ferrule is movably coupled to the shell to permit it to respond to loads imposed by an optical fiber connector and includes an electrically conductive cap to shield a portion of the port housing proximate the ferrule.

Abstract: An integrated latching mechanism for use with a user pluggable electronic module, such as an opto-electronic transceiver module, is disclosed. The latching mechanism allows the user to selectively latch the module within a corresponding host port by manipulation of a pivot lever. Movement of the pivot lever causes a locking pin to extend and latch the module within the port. Conversely, movement of the pivot lever can disengage the locking pin and thereby allow the user to extract the module from within the port. The pivot lever can further include a biasing member that biases the pivot lever in a locked position.

Abstract: An integrated latching mechanism for use with a user pluggable electronic module, such as an opto-electronic transceiver module, is disclosed. The latching mechanism allows the user to selectively latch the module within a corresponding host port by manipulation of a lever formed on a bail. Movement of the bail causes a locking pin to extend and latch the module within the port. Conversely, movement of the bail can be used to disengage the locking pin and thereby allow the user to extract the module from within the port. Operative movement of the lock pin is accomplished by forming a cam on the bail lever. Movement of the bail lever thus causes movement of the cam, which corresponds to movement of a locking pin from a latched to a delatched position. The bail may be substantially disposed either within or outside of the electronic module.
