Abstract :
The broadcasting of 10 wavelength channels over 29.6 km of fibre in a passive splitting network to 7203 potential user terminals, using a single broadband Er-doped fibre power amplifier is reported. Wavelength selection was achieved by a tunable grating filter. A total broadcast network capacity of 2560 Tbit/s km user has been achieved with a single amplifier providing all the required power.
