OPTICAL SUPERVISORY CHANNEL TRANSLATOR

摘要

An optical line interface is provided for communicating between terrestrial terminal equipment and an undersea optical transmission path a WDM optical signal having a plurality of wavelength components. The optical line interface includes a signal processing unit for transforming WDM optical signals between optical layer transport protocols employed by the terrestrial terminal equipment and undersea optical layer transport protocols employed over the undersea optical transmission path. The optical inter interface also includes an optical supervisory channel translator for transforming an optical service signal received at a first wavelength from the terrestrial terminal equipment to a second wavelength employed by the undersea optical transmission path for communicating service information.
