ABSTRACT:
A method and apparatus for monitoring the quality of an optical link is disclosed. According to a first aspect of the present invention, a method for determining a quality of an optical link is disclosed. The method includes identifying a known signal and transmitting and receiving the signal over an optical link. The method also includes comparing the received signal to the known signal using optical correlation. The method further includes determining a quality of the optical link based on the comparison.
