    摘要： A point-to-multipoint communication system is presented to enable a reliable, high quality communication using multiplexed optical signals between a central office equipment and a plurality of subscriber's equipment. The system is provided with a plurality of office transceivers in the central office equipment, and the each of the subscribers is provided with at least one subscriber transceiver. The system is designed so that a redundancy system is built-in by providing one of either the office transceivers, a plurality of subscriber's transceivers or the optical connection device, to connect the two sets of transceivers at all times. One of these redundancy systems provides an operating connection between each of the office transmitters which are connected to the office transceivers and each of the subscriber transmitters which are connected to the subscriber transceivers. Therefore, when a malfunction occurs somewhere in the optical network, the least number of the malfunctioning components need to be switched over the the normally functioning system to maintain continued communication services. The present communication system is designed with the least number of active components, therefore, the failure probability is significantly decreased, and repairs if necessary can be preformed quickly. The overall effect of the present system is that interactive point-to-multipoint communication services of high quality and reliability are provided at reasonable cost.

    摘要翻译： 提出了一种点对多点通信系统，以使得能够在中心局设备和多个用户设备之间使用复用光信号实现可靠，高质量的通信。 该系统在中心局设备中设置有多个办公收发器，并且每个用户设置有至少一个订户收发器。 该系统被设计成通过提供办公收发器，多个用户的收发器或光学连接装置之一来内置冗余系统，以便在任何时候连接两组收发器。 这些冗余系统中的一个提供连接到办公收发器的每个办公室发射机和连接到订户收发器的每个用户发射机之间的操作连接。 因此，当在光网络中的某处发生故障时，最少数量的故障组件需要在正常运行的系统上切换，以保持持续的通信服务。 本通信系统被设计为具有最少数量的有源部件，因此，故障概率显着降低，并且如果需要可以快速进行修理。 本系统的整体效果是以合理的成本提供高质量和可靠性的交互式点对多点通信服务。
