Subcarrier multiplexing for the subscriber loop and local-area network.

This paper describes the applicability of subcarrier multiplexing to lightwave multiple-access networks. Specific subscriber loop and LAN architectures are described and evaluated in terms of performance and component requirements. It is shown how currently available microwave and lightwave components can, by using subcarrier multiplexing, be used to provide high-capacity networks. For example, the proposed LAN can support 1024 users at a continuous bit-rate of 1.5 Mb/s, per user. In the proposed loop architecture, 45 Mb/s digital video, voice and data services, for 8 subscribers, are multiplexed onto one laser and one fiber.
