Abstract :
The authors report experimental investigations, at 565 Mbit/s, of an inline cascade of five semiconductor laser amplifiers with a total fibre to fibre gain of approximately 52 dB. Stable operation is achieved even in the absence of intra-amplifier optical filters and isolators, thus ensuring maximum optical system bandwidth and transparency.
