Advanced technology for fiber optic subscriber systems

Abstract

Key issues in handling optical frequencies for broadband communication services and constructing optical frequency-division multiplexing (OFDM) systems are discussed. The configuration of OFDM transmission systems, their use of multichannel frequency stabilization, multiplexer/demultiplexer, tunable filters, and common amplification systems, and the effects of optical-fiber nonlinearities of OFDM systems are described. The applicability of OFDM to various kinds of telecommunication networks, such as high-capacity end-to-end transmission, information distribution, multinode networks and subscriber systems of both transfer and access networks is discussed.< >
