M. Nissov et al., IMPROVED NOISE PERFORMANCE IN NONRETURN TO ZERO SYSTEMS BY USE OF DISTRIBUTED FIBER AMPLIFIERS, Electronics Letters, 32(20), 1996, pp. 1905-1907
The system implications of using distributed amplifiers in nonreturn t
o zero transmission systems are investigated. Doubling of the amplifie
r spacing while maintaining the received signal-to-noise ratio by the
use of distributed fibre amplifiers is predicted.
