In my last job we had a bloke who they always said if you removed everything from his house that belonged to the firm his house would fall down

I may have already asked, but is shielded cat5e necessary? As I understand it, electrical interference and noise is only as issue if the cable is laid parallel to electrical cables?

UTP is unshielded.

Parallel and close!

I have network Cat5e, telephone, TV aerial, FM/DAB radio, mains power & alarm running down the same riser here at home. Power is probably 100-150mm away and a little separation on the rest but suffer no problems at all.

Screened is OTT.

100-10mm?

The RJ45 faceplates will be sited about 5 inches (>100mm) away from any power sockets so that should be plenty of clearance, but I will ask the sparky doing the work to ensure that the cat5e runs 90 degrees across any power cables under the floorboards on the way to the cable rack.

It should read 100-150 mm although there are a couple of places where it is a lot less!

Your spacing should be fine - just look at office installations where power, data & telephony all run in 100mm trunking (with separators) and the outlets are adjacent.

Thanks, 100mm is a useful figure to remember for these purposes

Out of interest though have you done any throughput tests to check whether you can get the full 1Gbps without problems?

I guess though unless you're pushing the maximum cable length of Cat5e then you're unlikely to suffer.

From PC to PC through a Linksys/CISCO switch I have achieved well over 750Mbps. My feeling is that it could be the PCs and discs that are slowing up the transfer.

Yup, you're proabably hitting the limits of the PC's discs and bus.

750Mbps. Enough for most people, surely?
