your findings are from where?

In addition to the Wikipedia info I posted earlier:

http://www.10gea.org/1000base-t/#BAS...GORY_5_CABLING

Network managers and planners will be able to run 1000BASE-T over Category 5 cabling. The IEEE has written the 1000BASE-T Standard for Gigabit Ethernet operation over the Category 5 cabling systems installed according to the specifications of ANSI/TIA/EIA-568A (1995). Member companies of the GEA have demonstrated 1000BASE-T products operating on Category 5 cabling. There should be no need to replace existing Category 5 cabling to use 1000BASE-T.

Anyway, just because an article is old doesn't mean it's wrong.

too old for my liking

I'm running a GigE network over Cat5 at home, gigabit switch to both computers, I get ~700Mbit throughput between a laptop and a desktop, it'll do.

In fact there's very little difference between the cable itself and the only reason as to why cat5e is supplied these days is that it's been superseded in manufacturing by cat5e with all of the factories only making the higher spec..

I wonder how few vm customers actually need the 100m to 320m capability of Cat5e??? and how many people would actually realize if you swapped all of their cat5e for cat5

Sure about this? All standards indicate a maximum segment length of 100m, absolute maximum, before active repeating is required?

See TIA/EIA 568-5-A - the Cat5e cable standard. It mandates 100m max segment length regardless of the speed you're running at due to timing issues to allow the CS part of CSMA/CD to work. Signals can't propogate down wire quickly enough to avoid it breaking without something active breaking the electrical domain.

Best get off this website and indeed the Internet then, TCP/IP which you use to reach the server it lives on and HTTP which it's using to deliver the web pages via all pre-date 1999 quite considerably.

could be better

Well until I get an enterprise class NAS it'll do... My hard drives won't do anywhere near 1Gbit, and I'm only on Virgin XL BB.

cat5 can probably do gigabit but I wouldnt deliberatly buy it as cat6 is out there on the market for around the same cost anyway.

[Skie]

I've actually seen various things over the years that state Cat5 is only really reliable with Gige at 10m lengths. Cheap Cat5 was pretty common too and was utter pants, back in the days when speeds over 100mbps were still theoretical or reserved for large corporations consumer stuff was never really manufactured to a decent standard.

There shouldn't be much cheap Cat5 left though, 5e replaced it long ago and as others have said Cat 6 is standard now.

You are right maximum length without a repeater is 100m. Usually 90m max length for the horrizontal cable allowing for a 5m patch cable either end.

Barnsley has been done then. Not sure whenBut I thought that you were meant to get the Superhub?
