The rudders look possibly consistent with J-35 rather than J-35A, though the resolution seems a bit low to tell definitively where the line is.
But that's fair enough, I was just wondering if I missed something.
I already told you. It comes directly from the horse's mouth. The source is right there in the article.
I can tell you that everything stated in the article about the Su-57 avionics is confirmed via other (Russian) sources. This is a serious article not just some fantasy concoction.
The following paragraph is from the article. It sounds like data communication between radar and sensors to computers, for example 10-100 Mbit/s seems pointing at ethernet. I don't think fly control needs such high bandwidth that the engineer talked about. Avionic is not fly-by-light. Also about the "noise immunity" (SNR), it is more important to high bit-rate (low voltage/current) signals. For a low bit-rate data stream in fly-by-wire, increasing voltage is easier to supress noise. The emphasize on SNR makes me think that the engineer was talking about something between radar and computers.
Data exchange for Su-57 onboard systems are conducted via fiber-optic channels. The fourth-to-fifth generation transition from copper to optical fiber allowed the designers to significantly increase the speed and volume of data transmission, while reducing the weight of the cable network and improving its noise immunity. Whereas data transmission over a traditional copper cable produces a speed on the order of 10-100 Mbit/s, fiber optics is almost 8 Gbit/s.
Fly-by-light isn't such a big deal in implementation in terms of today's technology, it is only replacing coper cable with fibre, adding light/electric convertion at two ends, it is still electro-hydraulic in essense. So some new aircraft using it isn't surprising, but as I said there is no evidence.
Note, I am equally skeptical about the claim of J-35, in reverse I would equaly belive that both Su-57 and J-20 uses fly-by-light.

Check this out.
Ethernet is one of the standards used in aviation to connect the avionics together.
You also have to remember than modern avionics centralize most of the processing. While in older systems it was common to have a distributed architecture of processing nodes (often analog) which were then controlled by a central processor unit (often digital), now the central processor unit (digital) does most of the grunt work. This is also how you can more easily implement sensor fusion. This is possible because modern digital computers are more powerful than the ones available when 4th generation aircraft were designed.
So let's say instead of doing much of radar signal processing as close to the signal input and reduce the volume of information as it gets passed up to the central processing unit, the central processing unit does most of the work itself.

That's... A J-35A with a J-16.Spotted again.
