RACE 1051: demonstration of a multigigabit technology for provision of digital video services

Within the RACE project 1051 'Multigigabit Transmission in the IBCN Subscriber Loop' the major technologies for 5 and 10 Gbit/s fibre-optic transmission systems have been developed and tested in system demonstrators. Components and building blocks for all system functions such as multiplexer, laser driver, receiver preamplifier, main amplifier, regenerator and demultiplexer/channel selector have been realized in the form of Sil bipolar chips for both bit rates. Integrated transmitter and receiver modules have been built around advanced optoelectronic components. With a cascade of four optical amplifiers it was possible to bridge a budget of 100 dB at 10 Gbit/s without applying optical filters. This means that more than eight million customers can be supplied by only one optical transmitter.<
