Fiber-optic distribution system for broadband signals

摘要: A fiber-optic distribution system is disclosed which distributes broadband signals received by a network termination circuit from communications (B-ISDN or cable-television network) among plurality of subscriber terminals. The (4) contains devices for separating forward channel and backward channel. It also includes electric-to-optical optical-to-electric transducers (5,6). multi-port coupler (10) made the fusion technique interconnects optical fibers (12, 13, 14). On subscriber's side, each these forms one terminals (32). (16) signals, all other (17, 18) are combined to form narrow-band They connected common large-area photodiode (6). As channel, fact that photodiodes, such as PIN diodes, relatively slow does not cause any bandwidth problems.
