313 km Transmission Experiment at 1 Gbit/s Using a Low Chirp Laser and Optical Amplifiers.
01 January 1988
The use of four in-line semiconductor laser amplifiers is reported in an optical fiber transmission experiment. Using direct detection at 1 Gbit/s, a transmission distance of 313 km of non-dispersion shifted fiber was achieved. This is 142 km longer than previous experiments at similar data-rates and the first time optical amplifiers have been used to improve the transmission distance for fiber optic communication systems.
