I don't know what you mean by 'really short runs' but I have a ten-metre Cat5 cable from circa or earlier and it handles Gigabit flawlessly. Might just be luck though. Just FYI, Cat7 does not exist in and did not exist in It's a manufacturer sham to drive sales. Theoretically, CAT5 should suffice. Higher spec cables are not expensive so most of the times I'd recommend the upgrade. Dani Dani 1, 1 1 gold badge 13 13 silver badges 19 19 bronze badges. Definately possible, but not recommended.
Sure, you're not going to get optimal results with CAT5, but it's all about your situation. If you've already got CAT5 run, and you have the budget for GB switches but not new cabling, get the switches, you'll see results If you haven't run cable yet, get 5e or 6, without a doubt It's going to work , without a doubt, but not as close to rated speed as you'd get with a higher grade of cable.

In worse situations, the negotiation occurs, but the link fails and you find you have to manually lock the connections to Mbps till you take care of the issues.
The CAT5 installation is so marginal that the devices negotiate and connect at Mbps with tasty slowness, but are able to pass traffic reliably at the fallback speed. The only one that will reliably connect at 1Gbps is the Cat 5e Mhz. Any others would transfer at a slower rate. However, if you do get a Cat5 Mhz to transfer at 1Gbps over a short physically short cable connection then you still run the risk of packet loss.
CAT 5e is an enhanced version of Cat5 that adds specifications for crosstalk see below. Cat5e cable is completely backwards compatible with Cat5, and can be used in any application in which you would normally use Cat5 cable. This effect can result in slow network transfer speeds, and can even completely block the transfer of signals over the cable. Cat5e cable has been improved over Cat5 cable in this respect, and crosstalk has been greatly reduced.
The greater the bandwidth of a system, the faster it is able to push data across a network. Sounds like you over-thought something when you made that reply!!! Doing a little parsing of the first sentence says at the speed they determine will pass over the wire.. In standard English, wire and cable can be interchangable and something else was negotiating, not the wire So, I guess you were assuming as it wasn't me DavidSchwartz - In my moonlighting as a network tech, after ordering a building rewire or two, it's funny how people try to save money.
First rule on rewires should be "throw away all the patch cables. FiascoLabs: I only commented on your comment "Sadly, a piece of cable cannot negotiate. Perhaps you were kidding there. Anyways, much has been spoken about a humble cable! Show 2 more comments.
Cat 6 isn't basically the same as 5e. It's 5e and 5 that are basically the same; 6 has a different wire gauge, among other differences. Granted, they do make it, but you really have to go out of your way to find it from my experience. Yeah, I realized that, and edited it out of my comment. You're right about that part.
For future readers: I originally claimed cat 5e was often MHz. Who is copying whom? If you are using them as a source, you should cite them especially if quoting. Show 1 more comment. What was the average length of the Cat 5 runs?
Even Cat 3 will run Gigabit if the cable is 20cm long. The average length was Thank you for that detailed information. What would be interesting is to test a Cat 5 cable for Cat 5e performance at meters, unless your tester already takes the cable length in to account. I do not think that the tester takes the cable length into account, but feel free to seek out more information on the certification tester here: flukenetworks. However that is just speculation, and we have had no practical problems using the system for gigabit.
Low density port rack panels have approximately 2 to 5 mm spacing between each socket. Dale Mahalko Dale Mahalko 1 1 silver badge 4 4 bronze badges.
