Ho-link HD-AHD/HD-CVI/HD-TVI Optical Transceiver adopt the advanced uncompressed HD composite video and high velocity digital optical transmission technologies which convert the AHD, HDCVI or HD-TVI composite signals to optical signals to achieve long distance(as far as 120Km) transmission through fibers. Ho-link AHD/CVI/TVI Fiber optic transceiver can simultaneously transmit 1-8 channels AHD, HD-CVI or HD-TVI over one multimode or 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 input video format as 25/30/50/60fps@720P & 25/30fps@1080P.
