They are becoming consumer parts, it would help if you expanded your mind a little bitBecause for the most part fibre and DAC cables are not consumer parts and with no useful standard for 25Gbps over twisted pair it severely limits the likelihood of even SFP28 switches for the SOHO market.
You are not going to see consumer level 25Gbps internet access for consumers for a considerable period of time given the current price point of 25Gbps capable routers. They would need to drop by a factor of around 100 to make it viable.
It's not even about internet access, we have 10G SFP+ ports on consumer routers even before 10G is even half common
So if not many people have 10G FTTH does that mean its not consumer then?
