QuestTel's L-4SDI-FE-HD-TX/RX is a reliable high performance, 4-channel HD-SDI video over singlemode fiber transmitter and receiver extender solution, which provides real-time, loss-free HD-SDI transmission audio embedded) over a single optical fiber cable. Furthermore QuestTel's 4CH PRO-SDI Gear provides a bi-directional RS485 data channel and optional audio/contact closure/RS422/RS232 data transmission, which can be widely used in TV live broadcast, high-definition video conference, high-definition video monitoring, intelligent transportation system and public security system. Fiber optical transmission excludes electromagnetic noise factor, it makes this product a perfect solution for efficient, reliable and secured SD/HD-SDI signal transport.
