One way SDI transmitter and reveiver with 485
The SD/HD-SDI transmitter and reveiver is the low cost transfer device for one way SD/HD-SDI video by single mode and multimode optical fiber cable transfer. SD/HD-SDI/3GSDI transmitter and reveicer is designed by digital optical transfer technology, transfer long distance one way SD/HD-SDI/3GSDI video signal(optional one way reverse 485 control signal) on one single mode optical fiber. Support SMPTE292M.SMPTE259M.SMPTE424 signal. The device comprise of tramsmitter and receiver: Transmitter convert SDI signal to optical signal; Receiver convert optical signal to SDI signal and output.
Main features
l Support 1 channel HD Video+1 channels Backward Data via one Single Mode Fiber.
l Support Standard Definition to SDI（270Mbps）, High Definition to SDI（1.485Gbps）and 3G-SDI（2.97Gbps）Video formats.
l Built-in 3G-SDI Line Equalizer, Reclocker and Cable Driver, to recover its signals and Jitter and restraining functions perfectly.
l Broadcast Signal Quality, according to SMPT standard completely.
l The Maximum Cable Length of Belden 1694A：SD 400m；HD 200M；3G 140M.
l Single Mode Single Fiber, supporting the transmission distance from 0-100Km.
