16-channel heterodyne broadcast network at 155 Mb/sec

There has been considerable interest this year in exploring heterodyne reception techniques for use in fiber distribution networks, especially broadband-ISDN networks. These will likely be implemented using conventional fiber technology, but could later be upgraded using heterodyne receiver technology. Heterodyne systems provide several key advantages: the ability to transmit many channels simultaneously, to tune the receiver to select a single channel, and to detect smaller signals. The current thinking is that B-ISDN networks will use a double-star topology, employ a SONET digital transmission standard, and also include broadcast video.
