The F-4V-Rx is a Thor Fiber 4-channel composite video over fiber receiver for easy transport of all your video over a single-mode (20km) or multimode(3000ft) fiber. There are many high-end security cameras out there that still shoot in standard composite video. Our line of F-SEC fiber transmitters is designed to extend the life of this equipment. Our fiber optic security transmitters still use the same high end 10-bit digital encoding that our broadcast transmitters use, just in a less expensive chassis. We offer many different configurations and services with this line of products. In addition to video we can also carry data, Ethernet, telephone, or audio in the same unit. Speak with a sales representative today to discuss specific options and pricing. Our units come with standard single mode optics with a transition distance of up to 20km. Other options for special wavelength optics and power outputs are available upon request.
