GIGALIGHT’s 4-channel 3G-SDI optical extender is used to extend the range of 4K video transmission through optical fiber between SDI source and receiver equipment, and with 3G-SDI optical module, the transmission distance can be extended by up to 80km. The product is divided into transmitter and receiver: the transmitter receives SDI video signals from the video source, passes through the coaxial cable equalizer, and then converts them into optical signals for transmission through optical fiber; The receiving end converts the optical signal into an SDI video signal, which is then amplified by a coaxial cable driver.
