摘要：
We have developed novel wide-dynamic-range WDM optical fiber amplifiers for 10 Gb/s, 32-channel SMF transmission systems. These amplifiers consist of a low-noise preamplifier section, a mid-attenuator for loss compensation of a dispersion compensator and ALC operation, and a post-amplifier section for a high output power. These WDM amplifiers are also designed to allow in-service channel upgrades and in-service accommodation of external pump units. We have confirmed the superior performance of these WDM amplifiers by performing 320 Gb/s (10 Gb/s x 32-channel) transmissions over 320 km (80 km x 4 span) of SMF, achieving a bit error rate of less than 10(-15) for all channels.
