10 GbE is still iffy even with CAT6 cabling over copper which complicates deployments and user experience. As a result, prosumer type devices like recent AMD x570 motherboards and the upcoming Intel Z690 based ones are including 2.5 GbE ports that are rated to work over CAT5E and provides enough bandwidth for a few hundred GBps with a lot less power usage on the switch side (something like < 4w / port seems common) and makes it easier for low cost passively cooled switches to work alongside a switching SoC that doesn't need to be terribly sophisticated to hit the latency requirements needed to support 2.5 GbE.
- fleventynine 5y ago10GBASE-T is power hungry and unreliable, but dirt-cheap 10GBASE-LR and 25GBASE-LR transceivers work great up to 10km. If only they could figure out how to fit the transceivers into mobile-friendly packaging. But for a workstation they're great.
- Sebb767 5y agoThat's true, I actually run fiber in my home for that reason. I think the problem with fiber is, though, that the technology is pretty unknown to consumers and working with fibers is a lot harder than working with cables; they take a lot less abuse before breaking, for example. But if someone is going for 10Gbit+ in their home network, I can highly recommend fiber.
