Fiber-Optic Receivers

Communications Networks of Danbury, Connecticut, doing business as ComNet, has introduced fiber-optic video receivers for use over multimode-optical fiber. The devices receive a single baseband video channel as an optical signal from up to 2.5 kilometers away and convert the signal back to baseband video for monitoring. The FVR10 features a manual-gain adjustment, while the FVR11 features automatic-gain control  to adjust changes in the camera output that might degrade video quality. These are among the first entries in the extensive line of fiber-optic video and data- transmission products planned by the new company.
