Hub to hub cable lengths

By NormH3 ·
Ok all you network hardware guru's.. I have seen documentation that states maximum cable length between 100mps hubs is only 5 meters yet maximum length between 10mps hubs is the 100 meter standard. Just curious if this information is correct. Should be any easy 90 points for someone. A link or two to back up your reply would be helpful.

You have seen poor documentation.

Actualy the cable is the most important fact here. (along the different enviorment the cable is run thru).

The maximum lenght a cable cat5e is guaranted is 100m. That means that in optimum conditions there will be 100Mbs over the cable (or 10Mbs if one of the swithc in just 10Mbs). In real life this differes alot. If the cable is good quality and is routed away from any powerfull electric fields you can safely reach lenghts of more than 100m.

If you want to use 150m+ lenghts than you must use repeaters, or other switches along the way.

You could have a cat5e cable of 300m, but even though you use 100Mbs switches, probably you won't be able to transfer data faster than 50Mbs.

yeah.
and my 2 cents, i don't seen the maximum length rule broken as much as i've seen the minimum rule broken.
no shorter than 1 meter.
but i have about 50 12" cat 5 patch cables at my punch down to switch rack and it works at 100mbs everywhere...
2 cents: just bought a $200 RTD from www.triplett.com so can get some hard numbers.
backdoor of free informal informatino here is sales people that sell the expensive tdr's.
possily take a free seminar in testing utp. the companies that sell cable and testers (northern wire and cable, blackbox) have free seminiars on how to use them that by definition include information like you want to know about standards...
check out www.blackbox.com, they used to have good info at back of their catalog for do it yourselfer's

maximum cable length is(cat5/5e/6) 100m.

Now there are some senarios where you may not get 100mbps more than 10-20 meters but 10 mbps will work on same cable, this mostly happends when cable is not terminated as per standard (1,2 & 3,6 pair).
