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. Electronic and optical adjustments are never required. LED indicators are provided for instantly monitoring system status. Devices are available for either standalone or rack-mount installation, which is suitable for different working environment. It supports 2MP 1080P 720P Camera.



  • Non-compression coding technology
  • Automatically identify formats of input videos.
  • Support transmission of combined AHD, HDCVI, HD-TVI or CVBS signal and controlling PTZ data RS485 simultaneously though fiber optical cable
  • Support 2MP 1080P 720P Camera
  • Through LED indicators to inform its functional mode
  • Industrial wide range of operational temperature
