ABSTRACT:
A method and system for the transmission of signals over a large capacity local access network which provides users a dedicated two-way link to a central office The network is built along a single optical fiber ring. Connection to the fiber is obtained by combining time and frequency division multiplexing techniques and by using an optical channel-dropping filter. Optical signals are generated at the central office. The users have a simple device integrated with the channel-dropping filter to receive and transmit data without the use of an optical source.
