Twisted pair and optical fiber, the characteristics are as follows:

Twisted pair is divided into shielded twisted pair (STP) and unshielded twisted pair (UTP)

, shielded twisted pair (STP) is characterized by good anti-jamming performance,

Medium Transmission distance,

However, the requirements for installation (grounding) are relatively high.

unshielded twisted Pair (UTP) is characterized by

, the installation is simple, the transmission distance is long, but the anti-interference is not good, susceptible to the interference of strong magnetic field or electric field.

The characteristic of optical fiber is that

Transmission distance, strong anti-jamming performance, good confidentiality, installation and commissioning of a little complex, expensive.
