3G-SDI fiber optic transmitter for block cameras (two lines)
TL7070
The AIVION TL7070 interface with 3G/HD-SDI optical output with SFP compatible transmitter enables the transmission of 3G/HD-SDI video signals from HD block cameras. This means that distances of more than 10 kilometers can be bridged between the camera and the display/recorder device. The completely digital signal processing chain guarantees the best image quality. The camera is controlled via RS232 (supporting the Sony Visca protocol).
