With 10G Ethernet on the Pro model, you can connect all signals to the camera with the one Ethernet IP link connection. That means the camera feed, return program feed, timecode, reference, tally, talkback and control are all sent down the single cable. That's the same benefits of SMPTE fiber, but the standard 10G copper Ethernet cable is much lower cost. The Blackmagic Studio Converter allows breakout of all the video, audio and talkback connections at the studio end. It also includes a massive power supply that powers the camera down the Ethernet cable, so you don't need a power source near the camera. Plus you can fit 2 per rack unit using a Blackmagic Universal Rack Shelf!
