Is 10GBase-T (10G ethernet over copper) silly?

@wolf480pl According to you, cables don't work

@sjb no, that'd be too easy. They kinda work, and then stop working for unexplicible reasons.Or they do work, but make you realize you need software to go with them, and that software is where all problems live.

@wolf480pl much cheaper and easier to implement than fiber 10g, based on my research into this

@jasonnab from what I've seen, it's more expensive to the consumer than SR fiber or direct-attach SFPs, probably because it doesn't get economies of scale and a huge second-hand market

@wolf480pl@mstdn.io @jasonnab@mastodon.online Good things: - pre-existing cable runs probably can handle it- backwards compatible- users know how to handle it already- understandable enough so that people can just treat it like faster gigabit (no mess with different types of optics or module firmware/manufacturer restrictions)Cons:- More expensive since little/no parts can be bought separately from old servers, unlike SFP+ transcievers/DACs, requiring the expensive parts to be in-device.- Long runs requires more expensive cabling to be reliable- Comparatively large power draw (like 5W per transceiver IIRC)- Fancy signal conditioning required, hard to build cheaply.
