FORWARD ERROR CORRECTION WITH OPTICAL AND ELECTRICAL TRANSPONDER

Abstract:

A test instrument or host device can apply inverse transmitter and receiver functions to data transmitted or received by an electrical and optical transponder. The inverse transmitter and receiver functions are applied to counteract internal signal conversion processes of the transponder. Forward error correction and test pattern analysis may be performed on signals received from the transponder after the inverse receiver function is applied to the received signals.
