System for testing optical transmitters

A method of manufacturing a system for testing optical transmitters, the method comprising:

• providing a testing unit comprising:
• a testing board supporting one or more sockets via a top surface of the testing board, wherein each socket is configured to receive a substrate supporting a plurality of optical transmitters, wherein each optical transmitter is configured to convert electrical signals to corresponding optical signals for transmission by the optical transmitter;
• a sensor board supporting one or more optical receivers via a bottom surface of the sensor board, wherein each optical receiver is configured to receive the optical signals transmitted by the plurality of optical transmitters and configured to convert the optical signals to corresponding electrical signals;
• and
• one or more support rails attached to one of the testing board or the sensor board and configured to engage the other of the testing board or the sensor board, and the one or more support rails are configured to substantially align each of the one or more optical receivers of the sensor board with a corresponding socket of the testing board such that the plurality of optical transmitters is in optical communication with the one or more optical receivers in an operational mode of the testing unit;
• and
• providing a driver in electrical communication with the plurality of optical transmitters of the one or more sockets and in electrical communication with the one or more optical receivers of the sensor board, wherein the driver is configured to apply a current input to at least one of the plurality of optical transmitters and configured to monitor a corresponding output parameter.
