摘要：
The first use of an Er3+ fiber preamplifier for microwave multiplexed systems, and the use of an in-line Er3+ amplifier in microwave multiplexed systems for signal distribution, is reported. The improvement in receiver sensitivity as a preamplifier, without optical filtering, was 9 dB. No power penalty due to amplified spontaneous emission is found when the amplifier is used in a 30 channel signal distribution system. © 1990 IEEE
