摘要：

A 1.5-dB gain-flatness over 67 nm is achieved with a novel hybrid amplifier comprised of a distributed Raman amplifier pumped at two wavelengths and an erbium-doped fluoride fiber amplifier, Fourteen 2.5-Gb/s signals spanning 65 nm are successfully transmitted over 900 km using the new amplifiers. Low-noise characteristics compared to the same transmission line with discrete erbium-doped fiber amplifiers are also confirmed.
