An ATM cell based transmission system on a PON structure

An ATM-cell-based transmission system has been studied and optimized for fiber sharing in the customer access connection; it is oriented toward broadband-ISDN (provision of both interactive and distributive services) and takes into account the latest CCITT recommendations. A passive tree star topology with standard single mode fiber allowing at least eight customers to be connected is proposed. An example of application to residential customers is presented which takes into account possible evolutionary steps. It leads to a 622 Mb/s downstream on one wavelength and a 2 to 20 Mb/s per user upstream on another wavelength. The emphasis is on fibre to the home (FTTH) systems.<<ETX>>
