> The amount of time required to terminate a copper cable in the field is seconds,
This article is about Direct Attach Copper (DAC) cables which are not something you can field terminate. They use twinax copper and have special modules on the end.
You are thinking about standard RJ45 terminated cabling for 1GBASE-T or 10GBASE-T, which is a different.

Direct Attach Copper has slightly lower latency than fiber, but the difference is negligible. Both have significantly better latency than 10GBASE-T through twisted pair cabling.
Yes, thanks. It was confusing me for a second because no, no almost one is terminating twinax in the server room.
I had IT company recommend to me a bunch of fiber cables for a cleanup I was doing. They had about 20 or 30 laser modules we would need, and however much fiber.
When they asked why I planned on doing copper, I told him because each run is three fucking feet.
I’m not sure if they just didn’t realize that’s not what fiber is for or they didn’t know that DAC existed.
Many people don’t know about DAC. Like the comment above I think they see the word copper and assume it means the twisted pair they’re familiar with.
