You are installing network cabling and require a cable solution that provides the best resistance to EMI.

Which of the following will you choose for this installation?

a. UTP

b. STP

c. Plenum

d. PVC

The correct answer is letter "B": STP.

Explanation:

Shielded Twisted Pair (STP) wiring is a type of cable useful for networking applications composed by twisted pair of cables each one wrapped in foil. These cables are used in networks that require higher Ethernet standards with higher bandwidth, low latencies and low Bit Error Rate (BERT).

STP cables are usually expensive but have higher Electromagnetic Interference (EMI) resistance.
