Abstract:
1. An optical testing apparatus for measuring sensitivity of an optical component, the optical component having an input port and an output port, the optical testing apparatus comprising: an optical signal generator for generating an optical signal at a selectable power level; a first port for providing the optical signal as an output of the optical testing apparatus for coupling to the input port of the optical component; a second port for coupling the optical testing apparatus to the output port of the optical component; and an optical receiver for receiving the optical signal from the optical component via the second port and for analyzing the received optical signal for errors; wherein the optical signal generator and the optical receiver are secured on a platform, substantially rigidly fixed in relation to each other, and wherein the optical signal generator comprises an optical transmitter and an optical attenuator rigidly fixed in relation to each other.
