Abstract

The ability to provide a 55 Mbit/s service to 33.5 million PON subscribers is described, using an 8-channel sequentially-pulsed 1555 nm integrated multifrequency laser distributed to 4.3 million WDM PON lines through five amplifier/splitter stages. The wavelength-encoded pulses were modulated at 440 Mbit/s with an InGaAsP electroabsorption modulator, and then after 20 km transmission through singlemode fibre, they were demultiplexed with an arrayed-waveguide grating router. Error-free transmission was achieved
