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 line interface also includes an idler tone generator for generating idler tones at wavelengths corresponding to selected wavelengths components of the WDM signal that are not information-carrying wavelength components. An idler tone blocker is located within a signal path of the signal processing unit for selectively transmitting and blocking wavelength components of the WDM optical signal corresponding to the idler tones.

摘要： A method and apparatus is provided for monitoring optical signal quality between land-based terminal equipment and an undersea optical transmission path. The method begins by receiving an analog optical signal in which information is embodied in digital form from either of the terminal equipment or the undersea optical transmission path. The method continues by measuring a parameter such as the Q-factor, which reflects signal quality by analysis of the analog optical signal and not the information digitally embodied therein.
