Microwave-multiplexed wideband lightwave systems using optical amplifiers for subscriber distribution

A lightwave systems analysis shows that microwave-multiplexed wideband services can be distributed to large numbers of subscribers by using optically amplified multiple-star lightwave distribution networks. Through the use of well developed, readily available microwave electronics, this technique enables lightwave systems to take advantage of the large available bandwidth of single-mode fibres, GaInAsP lasers and GaInAs photodetectors.
