| 摘要 |
The present invention relates to a bidirectional optical communication system which is capable of sharing a single light source, located at a central communication point, among a large plurality of users. Additionally, the system, as defined in accordance with the present invention, requires only one single mode fiber between each user and the central location to support its bidirectional communication. The system of the present invention also has the capabilities to control the signal power sent to each subscriber, send more than one signal to each subscriber (voice and/or data and video), and switch to a back-up light source upon failure of the primary light source.
