FIBER LINK 2. 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 cen

FIBER LINK 3. Installation To install the Fiber Link, you will physically install the modules, connect the optical fiber, connect the input and output electrical signals, and connect power to the fiberoptic modules. Then you’ll verify correct system operation. 3.1 Physical Installation The Fiber Link is a standalone module. Install Fiber Links in dry locations protected from extremes of temperature and humidity. 1. Determine where you want to install the module, and make sure that there’s adequa

FIBER LINK NOTE Use RG59/U coaxial cable (part number ETN59-BNC) between the video equipment and the fiber units. The video equipment and the fiber unit should be no more than 100 ft. (30.5 m) apart. Terminate the coaxial cable with a female BNC and connect it to the fiber unit. Repeat for both ends of the link. 3.3 Optical Connections The standard optical connector on the Fiber Link is ST. Connect the preterminated fiber to the two fiber units. 3.4 Power Connections All standalone modules are e

FIBER LINK 4. Transmitter and Receiver Optical Indicators All transmitters and receivers have five active LEDs. See Figure 4-1. Level/Loss indicators are used in determining received optical power. The LED will glow in varying intensities of green depending upon the amount of optical power received. Any amount of green illumination, from barely visible to bright, indicates that sufficient light is a the receiver or transmitter. Red indicates insufficient optical power is being received, suggesti
