2-Ch 12G-SDI Fiber Optic Transmitter/Receiver
-
1.Product introduction
The 2-channel 12G-SDI optical transceiver developed and produced by Beijing Hcstcom transmits 2-channel 12G-SDI video signals through 2-core single-mode optical fiber, and the transmission distance can reach 20-80KM. Compatible with 6G/3G/HD-SDI video signals, it is broadcast-level that support clock recovery function. It is widely used in broadcast television stations, OB vans, medical operating rooms, video conference systems, command centers and other places.
