10 Base T and 100 Base T should have a distance limitation of 100 metres,if it exceed 100 metres the signal will attinuate if not extended by a repetre

The 100m limitation is the limitation that was placed on the standard for minimum distance for gaurenteed 100Mb transmission. Most manufacturers of equipment exceed the spec. If you are using a good quality cable and the cable is run where there is little chance of noise you would probibly be able to extend the distance. Theoreticaly what should happen is the transmission of data should slow to compenstate for the extended propogation delay, the time taken for the signal to move from one end of the cable to the next.

If you need further, then you just put in a repeater, which are not terribly expensive.

it`s basic limitation of utp cable but in practical it work good only for 85-90 mtr.
