5 Gbit/s optical transmission terminal equipment using forward error correcting code and optical amplifier

摘要

Using forward error correction (FEC) technology and erbium-doped fibre amplifiers (EDFAs), 5 Gbit/s optical transmission terminal equipment provides better than -40 dBm receiver sensitivity at a BER of 10/sup -11/. The experiments focused on the FEC feature of the removal of the BER floor together with long-distance repeaterless transmission.
