I need to broadcast and stream HD events using the QuestTel HD-SDI extender over fiber. I am looking into having the ability to do full multicam mixes in 4K. Before I even look at investing in additional equipment, is there such thing as a 30km 3G, 6G, or 12G SDI fiber that’s capable of UHD 6K? What’s the maximum distance a 6K SDI fiber can run? What are users doing for 6K long cable runs.
