Automated optoelectronic switched distribution system |
摘要 |
The present invention relates to an automated optoelectronic switched distribution system. A head end switching control center is provided. Optical fibers are connected to the head end switching control center. Subsidiary switching control centers (SCC) are connected to the optical fibers. Coaxial feeders are connected to the subsidiary switching control centers. Subscribers are connected to each feeder. Each feeder can carry numerous channels and each subscriber is connected to at least two allocated channels from the feeder. The subsidiary switching control center has remote switching and processing converters for receiving signals from the optical fibers and transmitting signals to a channel allocated to an individual subscriber. Each subsidiary switching control center has a remote switching and processing converter-transmit to receive signals from a subscriber's allocated transmit channel and to direct that signal to an output channel. The subsidiary SCC's may be automatically connected to each other via the area headend by single-mode optical fibers. Each SCC is allocated a designated spectrum of frequencies for automated reception of incoming 2-way channels. Each SCC can receive additional one-way and interactive channels on the same as well as additional optical fibers.
