Abstract :
Describes the use of an erbium-doped fibre amplifier in a 16-channel coherent broadcast network experiment operating in the wavelength range of 1538.8 to 1540 nm. The fibre-to-fibre gain was 22 dB and the amplifier dynamic range was 15 dB for the entire transmission spectrum. The amplifier was used to amplify sixteen 155 Mb/s signals on one output of a 16-by-16 star coupler, allowing a total span loss of 47 dB between transmitted and received signals. Satisfactory transmission system performance is obtained for error ratio of 10-9
