Cat 7 ethernet? - Page 3

post #21 of 23
Distance with fiber depends if it's multi mode or single mode.

But CAT5 ethernet is currently overkill for most buisness's infrastructure and switching equipment. It's extremely rare I've ever installed 1Gigabitps links throughout a building.

Yes, and that will decide for LEDs and Laser. Single Mode will be Laser and Multi-Mode is LEDs. You could try to stick with Single Mode but it is more expensive than just sticking Multi-Mode.

What do you use for backbones? I hope not CAT5.

Working for an AV integrator, we use fiber a lot to carry audiovisual signals. It is a much better solution than twisted pair (copper cat5/6).
I don't see how fiber is cheaper than cat 7. On newegg, there about the same price per foot. I don't know if when purchasing on a corporate scale it comes to less, but for residential purposes, which I think cat 7 will likely shine in, it doesn't seem significant if you could save 7% on a 15$ cable. Also amazon has 100 Gbit RJ-45 ( who cares if it is 'officially rj-45 or not, that what the vast majority of people and industry refer to it as ) for ~60-120$ for a 4-10 port switch.

EDIT: A+ looks to prove that Fiber is only light. Incorrect two ways are LEDs and laser. They might produce light but that is too vague.

EDIT2: RJ45 is the connector for the cable just like RJ11 for the telephone line.
I think fiber, specifically full-duplex multi-mode, is ideal for backbones and possibly certain buisness and city's with a great deal of EMI. But for the avrage residential user, I think it's not only an high performance choice to wireless N to what ever is next, but practical. Sure fiber can go kilometers with a full 10 Gbit signal, but how many residential customers having wired networks of that scale? 40 Gbits for 15 meters sounds pretty good to me. Plus if you needed to go say 20-25 meters, I couldn't see you needing anything longer, why not use a repeater to boost the signal?
