10m, 15m and 20m have been my usual installs but have done a 30m as well. However, I don't use Arc. Here's their specs.

FEATURES AND BENEFITS

4K, 5K, 8K, and 10K Resolution
48 Gbps, max 120 fps/HZ
SSF™ Fiber Optic Technology
eARC up to 20 meters, ARC up to 40 meters
SSF™ allows cable to be re-terminated if necessary
No external power required for most applications
HDMI to USB cord included in case of embedded power < 5V
Supports CEC

Questions for Brent since you deal with the manufacturing side.

Why don't they convert the ARC/E-ARC line to fiber optic as well instead of copper? I can guess that it would make circuity bigger and more difficult to fit into the head of an HDMI connector. Or it would draw too much power but both of those are just speculation.

Also, why are you worried about passive cables damaging equipment? Is this due to surges being transmitted more easily?

The longer distance for the Cleerline cable using ARC/E-ARC is that because of a larger gauge copper cable or just ideal conditions? Not trying for you to down any other manufacturers just trying to understand what properties make up a good cable. Like stated I think all three companies I mentioned make good cables and are good companies to deal with.

Thanks,

Bob

I understand that it's the ARC/eARC causing problems and that optical isn't an electrical conductor but it's still part of HDMI and that's why I don't like it.

I'm trying to understand the reason for not just using a power injector.......we wouldn't be having this discussion if they did that.

Cost and power consumption, sell through unit numbers is king.


Not worried about passive cables, only active ones.


As gauge increases so does termination difficulties.

Gee, and I thought that building systems that operate without faults was a good idea.

Maybe I should sell more systems, so the failures won't sting so badly. :)

They are (sadly) many great things that we could build, but we will never sell enough to cover R/D cost.

So, no manufacturing for the intrinsic value?

Worst. Day. Ever.

:)

We have made several items for intrinsic value (specific issue problem solvers), knowing that they may not even cover R/D costs (the HDM-GA2 is a recent example). However items these types of products require a balance of strong selling (read profitable) items to cover the R/D costs. The current market is such that every new idea requires much scrutiny and thought about "will it sell?", and "is the price right?", these questions stop a lot of cool niche items from existing (from all mgr's).

There have been a couple recent posts involving ADA. They had all kinds of solutions. I always wondered how much sell through they had. Evidently, it was not enough. It was also a lot simpler in a bygone era. A level shift, I/O pin shift, relay, and a timer or two could work miracle's. Now there are custom integrated circuits, constant testing with dozens of potentially connected equipment models, intellectual property licensing, and ongoing support. I always worried about the long term prospects for ADA.

Thanks for the reply
