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-interference performance
Medium transmission distance
However, the requirement of installation (grounding) is relatively high.
The characteristics of unshielded twisted pair (UTP) are
The installation is simple, the transmission distance is long, but the anti-interference is not good, and it is easy to be disturbed by strong magnetic field or electric field.
The characteristic of optical fiber is that
The utility model has the advantages of long transmission distance, strong anti-interference performance, good confidentiality, slightly complex installation and debugging, and high price.
