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： An optical WDM transmission system formed by integrating by using an optical WDM device at least two point-to-multipoint optical transmission systems which provide independent services by using optical signals of different wavelengths. It provides a plurality of user terminals with optical signals obtained by splitting with an optical splitter an optical signal which is wavelength multiplexed by the WDM device. The splitting numbers of optical splitters placed ahead of or behind the WDM device are set such that a loss from the center terminal to the user terminals of each optical transmission system falls within an allowed loss of each system. Since the splitting numbers of the optical system of each system can be set independently, each system can accommodate a maximum number of user terminals per center terminal within the allowed loss of the system.

摘要： The present invention provides an optical time compression multiplexing transmission system which suppresses the influence of optical reflection by a simple configuration without degrading transmission efficiency. The present invention is a 1:n (n being a natural number) time division multiplexing point-to-multi-point optical time compression multiplexing transmission system which comprises a decision element for determining whether or not the receiving signal which is outputted from a receiving element is a regular signal, an initialization element for initializing the operation condition of the receiving element when a receiving signal is determined to not be a regular signal by the decision element. When a signal is determined to not be a regular signal by the decision element, because the initialization element initializes the operation condition of the receiving element, the abnormal operation of the receiving element which is abnormal due to optical reflection which occurs by reflection can be returned to normal operation in a minimum amount of time.
