The difference between shielded twisted pair (UTP) and unshielded twisted pair (STP)

1. The difference between the appearance of unshielded twisted pair (UTP) and shielded twisted pair (STP): STP is wrapped by a layer of metal material to reduce radiation and prevent information from being eavesdropped. at the same time, it has a higher data transmission rate, but the price is higher and the installation is more complex. UTP has no metal shielding material, only a layer of insulating rubber package, the price is relatively cheap, flexible networking, its line advantage is good flame retardant effect, not easy to cause fire.

Second, commonly used is UTP unshielded twisted pair, the price is cheap and enough.

Third, the RJ-45 port is generally used in network construction. UTP and STP are just different in material and have the same use.

Fourth, STP is mainly anti-noise, but the price is expensive, unless the environment anti-noise requirements are very high, otherwise generally use UTP.

Generally, the network cable belongs to UTP unshielded twisted pair.
