ITU-T Recommendation G.977 is dedicated to interface and performance specifications for optical submarine systems using optical fiber amplifiers as line repeaters. It covers aspects related to single wavelength systems (SWS), wavelength division multiplexing systems (WDMS) as well as dense wavelength division multiplexing systems. wave (DWDMS, dense wavelength division multiplexing system). Annex A covers the physical implementation of underwater fiber optic and optical amplification systems.
