4Channel HD-TVI/CVI/AHD/Analog 4in1 Video to Fiber Transmitter and Receiver

4 Channels TVI/CVI/AHD Video to Fiber Converter Video Multiplexers

AIFON series digital fiber optic video transceivers can simultaneously transmit 1-128 channels of 8-bit digitally encoded video/return or bidirectional data/unidirectional or bidirectional audio / Ethernet / Telephone / binary input/output over one multimode or single-mode optical fiber. These multiplexers are typically used in applications where the cameras have P/T/Z capabilities.

Features *8-bit or 10-bit digitally encoded and non-compression video transmission   *Directly compatible with NTSC, PAL, and SECAM CCTV camera systems and support RS-232,   RS-422, and RS-485 data protocols   *Power supply and other parameter state indication, which can monitor the operation condition of system   *Support no-damage regenerative trunk of video   *Constant input optical power, and large dynamic range , no electrical or optical adjustments required . *Special ASIC design . *Industry-grade of operating temperature from -10℃to 75℃ , which is applied to the different working environment *Hot-swap function   *Stand-alone type or card-type installed in 19’’ 2U or 4U rack-mount chassis. *Optical interface: FC,ST, SC (optional) *Abundant signal interface, such as video, data, audio, telephone, Ethernet, 
 binary input/output and talkback *Max range 80km
