Wavelength division multiplexing -32 channels modulated at 10Gb/s and spaced at 0.4 nm over a distance of 6150 km

摘要

One of the limitations of undersea cable systems using wavelength division multiplexing is the wide bandwidth required for the optical repeaters. One simple solution is to reduce the wavelength separation. The transmission of 32 channels, spacedby 50 GHz and modulated at 10 Gb/s has been achieved over a distance of 6150 km with a mean BER for the 32 channels of 5.10{sup}-9.
