Shielded Twisted Pair (STP) connector is the Registered Jack 45 (RJ-45) connector.
Shielded Twisted pair cable
there is. shielded cable reduces the interference though
The twisting in a twisted pair cable helps make the cable immune to electromagnetic interference. These cables are of two types: Shielded and unshielded twisted pair.
A shielded twisted pair or STP is a copper telephone cable that secures signal-carrying wires inside a conducting shield. It main purpose is to reduce the possibility of electromagnetic intrusion.
So that other signals, such as a magnetic field, don't interfere with the cable signals.
RJ-45 connector
STP has an impedance of 150 Ohms.
It is called RJ45.
when we use some metal wrap around a single pair it is called shield like STP ( shilelded twisted pair cable) , when all shielded pair are overall wrapped by some metal it is called screen for example S/STP that is screened shielded twisted pair cable ,
Ethernet cable being shielded or unshielded twisted pair or CAT 5.
