Cabling - Twisted Pair (3)
Attenuation - the strength of a signal falls with distance over any transmission medium
Crosstalk - a major source of noise in twisted-pair cable; it is caused by signal "leakage" from adjacent wires
Comparison:
- UTP cat 3 - good; four twisted pair required with 25Mbps for each pair;
- UPT cat 5 - better; two twisted pair;
- STP - best
Application: Fast Ethernet, ATM, and CDDI
