Optical System with two packaged 1.5 μm semiconductor laser amplifier repeaters

The first demonstration of two packaged 1.5 μm semiconductor laser amplifiers in an optical system is reported. Total coupling losses for the fibre-tailed packages were 10dB and 13 dB, respectively. In a 140 Mbit/s intensity-modulated system experiment, using the amplifiers as linear repeaters, a total repeater again of 26 dB was achieved.
