The official maximum length is 100 meters/328 feet. Actual maximum depends on location, how the cable is run, and what's connected to it. I've got a run of cat5 (not 5e) that's consistent at 100baseTX speed at 508 feet, and some at 200 feet that barely work.

once again I agree with you Junkman, it does depend on where and how the cable is used. The cat5 is tricky i guess that is why we test after putting them in. I hope the cat6 will be more reliable

EIA/TIA standards say max length for any type of Horizontal cabling is 100meters. Does not care if it is Cat 3, Cat 5e, Cat 6, fiber, or two tin cans and a piece of string.

EIA/TIA 568b1 section 4.3 says " The maximum horizontal distance shall be 90m, independant of media type."
You might want to read up!!

There is NOTHING but a contract that says you have to follow the standards!! EIA/TIA standards are a recommendation. But if you have a contract that says you will follow the EIA/TIA standards or NEC. Then you better know what you are talking about.
Yes the EIA/TIA standards only recognize T568A or T568B as a pin out for commercial installs. T568A is the only one recognized for residential.
I am just answering the persons question. He wants to know the length and I gave him the answers per the standards.

lets wrap this one up folks... 100m limit is the entire channel... Device to Device including the patch cable... the hard length for wall jack to wall jack... is 90m for horizontal cabling with UTP...
These limits do not apply to fiber... they have their own table and do not fall under EIA/TIA 568.
