Abstract
This disclosure relates to optical line system equipment, which enables wavelength addition for long haul transmission. The system is configured to prevent contention of wavelengths added into a multiplexer. For example, an optical wavelength combiner, such as a multiplexer, may include components that are configured to detect potential collisions between existing wavelengths and a newly added wavelength, and block the addition of the conflicting wavelength while alerting the operator.
