cyril7: Yeah you should not be paying more than $120 for a box of 5e, and around $180 for cat6. I normally only put cat5e in, have run tests on the installs at Gigbit, no problems.


Hi Cyril

So running Gigbit lan, you find it is OK (given good quality terminations etc) on Cat5e?  Any difference using UTP as opposed to STP?

Im going to make sure Power wiring is kept away form my network runs, and do the normal thing of 90deg where crossing.

For my in wall runs I was going to use Solid, and then stranded for he patch leads.

I have had no probs with Gigbit on Cat5e. In typical domestic situations a 20m run is as big as it gets, so 5e is well in limit. If you had long runs (ie 50m or more) then the larger wire dia of cat6 would offer some advantage for Gigbit.

Keeping away from power feeds is good, however the main issue is to avoid long lenghts (ie 3meters or more) in parallel with power, if they are then attempt to seperate by 300mm or more. At all times mains and ELV cables should be 50mm apart anyway.

When installing cables, take care to not kink the cable or pull it two hard when installing. Solid is the correct cable for permanent wiring, stranded for patch leads. Dont use cable ties to hold bunches together, or if you do dont pull them too tight. I prefer to use insulation tape, and again not too tight. Insulation tape haveing a 10-15mm width distributes its wieght better across the cable providing less impedance distortion.

From my observation with most patch panel and keystone fitting suppliers, I can see no difference between a cat5e fitting and a cat6, I guess its just a matter of those fittings having been subjected to cat6 testing. Cat5e fittings and cables are designed for Gigbit ethernet. However cat6 cable is tested to a higher bandwidth for all loss, NEXT, etc with higher performance figures for most of those details thus making it easier to assure Gigbit will work especially if mishandled on install and on longer runs.
