Certified High Speed HDMI cables, with or without ethernet, meet and exceed all current HDMI specs that are currently offered on consumer devices (which use the HDMI 1.4 hardware
protocol) and are backwards compatible for devices that are using the HDMI hardware protocol specs earlier than 1.4/1.4a. If they are certified for the length
that you are using, that just means they are guaranteed to meet those specs because they've been tested, at that length, and passed. Anybody can make a cable and say they will meet the High Speed specs, but unless you can get a certificate that show they were tested and passed, there's no guarantee. Presently, there are no consumer devices that can take advantage of the ethernet channel in the HDMI cable so that's a future spec, if the mfrs adopt it. Just like 4k. High Speed cables have been able to handle 4k for awhile now but 4k is just starting to become available.
Optical cable is usually used to transmit discrete 5.1 audio from
the tv's internal ATSC tuner to the AVR. If the tv is smart, and the smart apps are capable of decoding 5.1, you may be able to get 5.1 audio that way as well if the program offers it. The simplest setup is to have all of your devices connected to the AVR via HDMI and then a single HDMI cable out to the tv. All of your audio is decoded and played thru the AVR with only the video being passed to the tv. Cable boxes can add another dimension to that because there are a couple of ways you can make your connection. Some connect their cable boxes, via coax, directly to the tv's Cable/Ant input and use the tv's internal ATSC tuner to scan and find the cable stations. Then a simple optical out and you've got 5.1 for all of the stations that offer it.
