Some feedback. I have been told MOCA is widely used in USA, and this is in-house coax cabling used for providing IP based services in multiple rooms. http://www.instructables.com/id/How-to-set-up-a-coax-MoCA-network/ Now, this doesn't have much to do with your 10GE talk as it's not going to be that fast, but anyway. So back to > 1GE speeds. It seems to me that 1GE is good enough for a lot of user needs. It's over 100 megabyte/s, most HDDs won't even transfer faster than this. Most devices do not have anything faster than 1GE, so it's a chicken and egg problem. I have a 100EUR fanless managable 24 port switch with 4 SFP ports. I imagine anything faster than this would require fans and would bring up the cost a lot. It would be ideal to have a 24 port 1GE + 4 (or 8) ports of 1/2.5/5/10GE for incremental migration, but I have 0 things in my home that speaks anything faster than 1GBASE-T (with RJ45 connector). I do have SFP+ based NIC cards and DAC cables, but I don't even use them (apart from occasional testing). The upgrade was from 100BASE-T to 1GBASE-T was fairly cheap and addressed a wide need, since 10-11 megabyte/s was slower than most HDDs even 15-20 years ago. Today, 100-110megabyte/s at 1GBASE-T speeds is actually still quite decent, and most people don't have huge amounts of data to move around. So for most people, anything faster than 1GBASE-T doesn't address a problem they actually have. Yes, for people handling 4k footage and doing video editing etc, they need faster. But most people don't. For them a 8-24 port 1GBASE-T switch is fine, and provides a networking solution that is not bottlenecking them in any significant fashion. 2.5G and 5G would be a good compromise, but it seems to be stuck in chicken/egg problem space. Most people actually don't even wire their computers today, it's all wifi, and even if they do wire them, the only NIC available is 1GBASE-T based. The iMac Pro is the first prosumer device I have seen that actually supports faster networking. If Apple or someone else actually released a thunderbolt based NIC that was decently sized/priced that did support 2.5G or 5GBASE-T, then this chicken/egg problem could perhaps be solved. Most people don't feel the need to connect these kinds of things to their laptop: https://www.startech.com/uk/Networking-IO/Adapter-Cards/thunderbolt-3-10-gbe-nic-chassis~BNDTB310GNDP https://www.akitio.com/adapters/thunder2-10g-network-adapter https://www.promise.com/Products/SANLink/SANLink2/10G-BaseT http://www.tehutinetworks.net/?t=LV&L1=3&L2=0&L3=0&L7=157 is interesting, as this is not huge. It also does 2.5G and 5G. https://www.anandtech.com/show/12422/akitios-thunder3-10g-adapter-now-available 300USD is still a significant chunk of money compared to the 29USD 1GBASE-T thunderbolt2 adapter that Apple sells. But still, with these kinds of products, there might be hope! -- Mikael Abrahamsson email: swmike@swm.pp.se
