Shieled Twisted Pair Cable Lenght?

[Takashi]

What is the longest STP Ethernet cable you have ever laid?

According to Cisco, the maximum cable length for STP is the same as UTP - 100' or about 330'. This is not to say that cables longer than this won't work. I personally have done very little with STP, but I'm sure I have pulled some UTP farther than 100m.

twisted pair is twisted pair whether it be UTP or STP... it's still got a practical limit of 100 meters. Distance limitations on twisted pair has to do with attenuation and signal strength.
