For the last fifteen years the attention of the fibre‐optic community has been principally focused on developing baseband digital transmission system for transmitting time‐division‐multiplexed voice channels over long distance and interoffice routes. Attention has now shifted to extending the fibreoptic network to the subscriber loop and to providing a multitude of new services through lightwave networks. Based on the results reviewed here, it is apparent that microwave‐multiplexing techniques provide a new and attractive way to transmit wideband services over optical fibre. By allowing lightwave systems designers to use and combine the complete range of available electronics, including both analog and digital electronics, and both baseband and microwave techniques, a great number of new possibilities arise for exploiting the bandwidth of lightwave components and for designing wideband lightwave networks. Over the next few years the microwave‐multiplexing techniques described in this article may fundamentally change the way we use lightwave technology.
