STP (Shielded Twisted Pairs)

As the name indicates, STP (Shielded Twisted Pairs) consists of pairs of wire that are shielded against electromagnetic interference.
Note the silver strands that 'wrap' the entire cable, as well as the silver foil that 'wraps' (or shields) each pair.

The connector (which is physically compatible with an RJ-45 socket) is also shielded from three sides.

This is an example of Cat 6 STP (Category 6 Shielded Twisted Pairs).
