Hi, I'm trying to figure out why no long (say, 100ft) 3G-SDI or 6G-SDI cables are being made. We run a long (100ft) HD-SDI broadcasting setup right now, and we're looking into purchasing one of the ATEM switchers. However, without long 6G-SDI cables to replace the 100ft HD-SDI cables, the 6G-SDI capabilities of those switchers become less significant.
I can't figure out why no long 3G-SDI cables are in production since the standard has been SMPTE approved since 2006. The only 3G-SDI cables that you can buy are patch cables. Likewise, I don't understand why 6G-SDI cables aren't being introduced into the market yet.
Can someone please explain why these things are so? Please feel free to provide technical specifics if the correct answer requires them. Actually, if the answer contains technical reasons that it's not practical or possible to run 3G-SDI or 6G-SDI over COAX, please do share them. Also, please feel free to share this thread with someone who may know the answer.
