cat6 at long lengths

post #1 of 6
Thread Starter 
Hi OCN, quick question, hopefully i get a more real world answer than what my research has yielded.

I have a cat6 running from my router to my desktop, it is 100ft long. Will I see any noticeable gain from dropping down to 30ft cat6?

CAT6 is rated to 100M (330FT) IIRC so dropping from 33M (100FT) to 10M (33FT) won't make much difference.

Basically no.

Well.... the propagation speed in a copper conductor is around .5 to .8 the speed of light.

That's about 150,000,000 m/s on the low-end.

So cutting 70m would save around 500ns.

That means ping would be reduced by 0.0005ms. thumb.gif

(This is assuming no external interference!)

While as some have stated is correct for the average user, the answer is no.
ON the other hand, if this is for 10Gb speed the answer is unquestionably yes dropping the length will allow you the speed increase. In order for CAT6a to attain 10Gb speed the length can be no longer than 15 meters.

Thank you to all.
Strange how cat6 is hardly affected while HDMI is severely affected.
