Overview
E-link HD-AHD/HD-CVI/HD-TVI/CVBS 4-in-1 Video Fiber Converter adopt the advanced uncompressed HD composite video and high velocity digital optical transmission technologies which convert the AHD, HDCVI, HD-TVI or CVBS composite signals to optical signals to achieve long distance(as far as 120Km) transmission through fibers. E-link 4Ch AHD/CVI/TVI/CVBS Fiber optic transceiver can simultaneously transmit 4 channels AHD, HD-CVI, HD-TVI or CVBS Video, 1-Ch 10/100M Ethernet, 1-Ch FXO/FXS Telephone and 1-Ch Backward Data RS485 over one single-mode optical fiber.
