the application of the hybrid optical amplifier in long-haul transmission system is discussed. The hybrid amplifier consists of a distributed Raman amplifier and an erbium doped fiber amplifier
of course a tunable filter. System sensitivity can be improved to -37.5 dBm after 160km’s transmission without FEC. Two other system configurations are also discussed and the advantage of the hybrid optical amplifier is analyzed in theory.
