Wink Cat5 Max Length


i know that cat5 max length is roughly 300 feet. I want to know if i throw a hub on the line can i extend that max length? and if so is there a point where the singal degrades due to the amount of hops from hub to hub?
I have about 1000 feet to cover and i dont want to buy hardware if i dont have.

I'm not a cable techie, but I'd be surprised if there were a problem.

Have you looked into a coax connection? You would need a couple of coax/ethernet converters. I have no idea how much they cost, but I see claims of 1000' in one hop.

Yes.

I am guessing maroonbaboon you mean fiber and not coax.

Googling for max length cat5 brings up a wealth of info, but basically you can do it with hubs, but you have to do it correctly. If you have too many hubs it will create problems. Look into the 5-4-3 rule.

You can have 100M + 100M + 100M which will get you to about 1000 feet.

Quoting michaelk:

No, coaxial cable, like TV antenna or cable TV stuff. If you google 'ethernet over coaxial' you will find some suppliers of converters. I guess it is basically just a cable modem. You can use them to set up a network over pre-existing coaxial cabling.

The lower attenuation compared to cat5 should give better range, and some suppliers mention 1000+ feet. I assume fibre is would be more expensive, but I'm just guessing - I never used any of this stuff.

maroonbaboon - Coaxial for use of ethernet is a thing of the past. Sure you can still get supplies, but that's to keep your legacy stuff going. Fiber is more expensive, but if you are doing long pulls from point to point (say wiring 2 buildings to the same network) it is the way to go in some cases.

Yes fiber would be expensive. Indeed a coax to ethernet converter would work as well if the OP wanted to purhase additional hardware. BTW ethernet over coax is not the same thing as 10Base2.

Yes, the old 'thin ethernet' with BNC connectors on the NICs has pretty much disappeared, although I see it was supposed to be good for 200m at 10Mb/sec.

I had thought maybe something better was around by now, without the expense of fibre.
