Introduction 2.1 Description The Fiber Link supports the transmission of video from a camera to a monitoring station and a data signal back to the camera over one multimode fiber. A single coaxial cable at each end of the link is used to connect the appropriate equipment to the system. In up-the-coax systems, video signals travel in one direction and control signals travel in the other direction for full-duplex operation. Video is transmitted from the camera back to the control center over coaxial cable. In conventional coax systems, signals travel in only one direction at a time. Control signals to operate the pan-tilt-zoom (PTZ) functions are transmitted from the control station out to the receiver/driver at the camera station. The Fiber Link is a single-fiber link...
