摘要： The principles of the present invention relate to aligning optical components with three degrees of translational freedom. A lens pin, a lens base, and a molded package are aligned in a first direction, a second direction, and a third direction such that the signal strength of optical signals transferred between a lens included in the lens pin and the molded package is optimized. The lens pin is mechanically coupled to the lens base to fix the position of the lens relative to the molded package in the first direction. Subsequently, the lens base and the molded package are realigned in the second and third directions such that the signal strength is again optimized. The lens base is mechanically coupled to the molded package to fix the position of the lens base relative to the molded package in the second and third directions.

摘要： Methods and processes are disclosed for calibrating optoelectronic devices, such as optoelectronic transceivers and optoelectronic receivers, based upon a measured avalanche photodiode bit error rate. In general, the method involves measuring a bit error rate for the avalanche photodiode and adjusting the reverse bias voltage of the avalanche photodiode until the bit error rate is minimized. This process is repeated for each of a variety of different thermal conditions. Information concerning each thermal condition and the corresponding reverse bias voltage is stored in a memory of the optoelectronic device.

摘要： Systems and methods for repeating optical signals. A scalable transceiver based repeater includes one or more transceivers. Each transceiver includes an optical receiver that receives a channel of an optical signal. The optical transmitter in each transceiver transmits the channel received by the associated optical receiver. A switch is used to redirect the channels, which may be in an electrical form at the switch, from the optical receivers back to the optical transmitters. The switch can also be used to add/drop the channels from the repeater. The optical transmitter and/or the optical receiver of each transceiver may also include a clock/data recovery circuit (CDR). The repeater is scalable because transceivers can be added/replaced as needed. A demultiplexor can separate an optical signal into the channels that are received by the optical receivers. A multiplexor combines the channels generated by the optical transmitters.
