Maximum distances using UTP ???

| Hi guys,
Please, help me with the following:
Q: A server connected to the fiber connection at a distance of 250 meters. What is the maximum distance from the hub that you can have a workstation attached with Category 5 UTP cable?
A: (by Brainbuzz)71 meters. There is a maximum distance using Category 5 UTP of 296 meters. Subtract 225 (???) from this and you get 71 meters. Add 71 to 250 for 321 meters.
I can't go through this.
Could anybody refer to some urls concerning the distances using Class I and II repeaters, please.
Are there questions like this on the CCNA exam?
Regards,
MateLom. | |

| Well, the server on fiber part sound like extra non-needed info. They have that on some of the Cisco questions.
From Cisco's book:
10BaseT - 100 meters (~300 feet).
100BaseT - 100 meters (~300 feet).
This would include your UTP, which is CAT5 copper wire. Brainbuzz says 296 meters, which is wrong. Unless they meant feet, but let's not try to interpert things.
Anyway, the maximum distance from a hub to a workstation is 100 meters using CAT5/UTP. The maximum distance between two workstations is 200 meters, 100 meters on either side of the hub. A hub is a repeater, it regenerates the signal.
Don't know where they got that funky math from though. Anyone else know?
Later,

| Their brain must be on a buzz, as 100 meters is the only answer I have ever heard. | |

That's not 100% true, there's passive and active hubs and only active hubs regenerates the signal. You can tell them apart by looking if they have a power connector as only Active hubs need external power. |
