2 CH Video/Audio/Data Transmitter
 
  Product Description：
 
  LWSFT series Digital Video Multiplexers adopt complete digital fiber transmitting mode, it can transmit more than 100 channels digital video, high-fidelity audio, telephone and low rate data(such as RS232, RS422, RS485, Manchester, BIPHASE and Binary input/Output). It adopts advanced digital technology such as DSP, FPGA, CPLD, to support dynamic and stationary picture high-fidelity transmitting and resist disturbance against intersectant signals and environment. It uses technical chip decorating on the whole surface and advanced switch, anti-electromagnetic wave radiation equipments, to make sure it can work continuously without troubles in any complex environment(eg. -40~+70℃ outdoor condition and electricity generating station). Complete digital technology of video insures that the video signals can be transmitted long distance without any waste, and the bandwidth of reverting video signals is over 8MHZ. Digital video multiplexer can make sure of high quality audio and video signals transmission no matter how complex the transmitting environment is.
