Abstract
Lasing of an optical channel at a particular wavelength is substantially prevented in an optical ring network by automatically verifying the presence of a break, e.g., termination, in the ring for an optical channel of a particular wavelength before allowing a node in the network to establish a 'pass through' connection for that optical channel. More specifically, a node attempting to establish a 'pass through' route for an optical channel received from another node is prevented from establishing the necessary connections to do so until it is confirmed that the optical channel of interest has been added to the ring or dropped from the ring at another node, thus indicating the presence of a “break” in the optical ring for that optical channel of interest.
