Abstract
A technique for multicasting an optical frequency channel in a multi-channel optical system is disclosed. In one particular exemplary embodiment, the technique may be realized as a method for multicasting an optical frequency channel in a multi-channel optical system. The method comprises splitting a first optical frequency channel in a pair of adjacent optical frequency channels into a first split optical frequency channel and a second split optical frequency channel. The method also comprises converting the optical frequency of the second split optical frequency channel to the optical frequency of the second optical frequency channel in the pair of adjacent optical frequency channels. The method further comprises selectively directing the first split optical frequency channel and the converted second split optical frequency channel to separate destinations.
