Paper Abstract

We review the recent progress of a 16-channel coherent broadcast network at 155.52 Mb/s, that uses packaged 1.54 μ m DFB lasers stabilized at absolute frequencies and a tunable, polarization-insensitive receiver. System experiments conducted show a 0.3 dB power penalty incurred at a channel spacing of 8.5 Ghz. Results using an erbium-doped fiber amplifier gave a fiber-to-fiber gain of 22 dB and an amplifier dynamic range of 15 dB, enabling the distribution of sixteen 155 Mb/s signals to one of 256 end-users at a distance of 102 km.
