SDI and Ethernet

1Ch SDI + 2Ch IP
over single Fiber

Nowadays more companies switch to web broadcasting, that's why QuestTel engineering team made a decision to integrate Ethernet over fiber technology with SDI fiber circuit. This new conjunction broadens area of usage for the extender, making it ultra-scalable and versatile solution for any live-event application, merging conventional SDI video distribution with IP based video systems, allowing you to distribute HD video over multiple networks simultaneously. Moreover these extenders come with embedded audio, RS-485 (optional RS422/RS232) data channel for camera control and dedicated AUX for additional audio.

Super Easy to use
