摘要： Systems and methods for controlling the modulation current of a laser included as a component of an optical transmitter, such as an optical transceiver module, are disclosed. Control of the modulation current, which affects various laser operational parameters, including extinction ratio and optical modulation amplitude, enables operation of the laser to be optimized, thereby enabling reliable transceiver performance to be achieved. In one embodiment, a method for modifying the modulation current in an optical transceiver module includes first sensing analog voltage data that proportionally relates to an actual modulation current of the laser. Once sensed, the analog voltage data are converted to digital voltage data. Using the digital voltage data, the actual modulation current of the laser is determined, then a desired modulation current is determined. Should a discrepancy exist between the actual and desired modulation currents, the actual modulation current is modified to match the desired current.

摘要： Methods for authenticating an optical transceiver module to a host are disclosed. The transceiver comprises a receive signal line for transferring data from the transceiver to the host and a transmit signal line for transferring data from the host to the transceiver in preparation for transmission to a communications network. The transceiver includes a controller having a processor in communication with the host, and a first memory register assignable by the processor. A consolidated laser driver/post amplifier is also included and features a pattern generator and a data switch. The pattern generator produces a string of bit values that serve as an authenticating data portion. The data switch selectively inputs the authenticating data portion to the receive signal line of the transceiver according to the state of the first memory register, enabling the authenticating data portion to be received by the host, thereby authenticating the transceiver.

摘要： An optical transceiver module having a plurality of optical subassemblies and a printed circuit board is disclosed. The transceiver module includes lead frame connectors for connecting the optical subassemblies to the printed circuit board. The lead frame connectors include a stamped and bent conductive lead structure that is encased in an insert injection molded plastic casing. The plastic casing provides electrical insulation for the conductors in the lead frame as well as mechanical support for the finished component. The lead frame connectors connect to the leads associated with the optical subassemblies and are surface mounted onto the printed circuit board to establish connectivity between the optical subassembly and the printed circuit board. The lead frame assemblies are generally more reliable and less expensive than using flexible printed circuit board structures to establish electrical connectivity between optical subassemblies and transceiver printed circuit boards.

摘要： An optical transceiver configured to perform filtering of digital diagnostics prior to the filtered results being made accessible to a host computing system (hereinafter referred to simply as a “host”) that is communicatively coupled to the optical transceiver. The optical transceiver includes sensor(s) that measures analog operational parameter signals such as temperature and supply voltage. The analog signals are each converted to a plurality of digital samples by analog to digital converter(s). A processor executes microcode that causes the optical transceiver to perform filtering on the various samples. The optical transceiver may then make the filtered result accessible to the host.
