Abstract
A method and apparatus for testing an optical cable is provided. In one embodiment, the apparatus may include a receiver for receiving a received pulse train through the optical cable. The apparatus may further include a cross-correlation system in communication with the receiver. The cross-correlation system may be adapted to determine a cross-correlation of the received pulse train and matched filter to an expected pulse train. The apparatus may further include a comparator in communication with the cross-correlation system. The comparator may be adapted to compare the cross-correlation to a threshold. The apparatus may also include an output transmitter, in communication with the comparator. The output transmitter may be able to output a comparison-result output that includes the results of the comparator comparison of the cross-correlation against a threshold.
