UTP cable is limited to 100 metre runs for 100 Mbit Ethernet, for higher speeds, the distance is less.
Fibre optic, though Ethernet is developing 10 gigabit UTP-based speeds for short runs.
STP is more reliable because it can withstand more noise abuse than UTP and therefore provide a more reliable transmission.
UTP
UTP Is unshielded and STP is shielded UTP generally being bulkier and more expensive.
Unshielded Twisted Pair (UTP) wiring typically uses four twisted wire pairs for data transmission. The most common categories of UTP wiring are Cat5e, Cat6, and Cat6a, each supporting different data rates and bandwidths. These twisted pairs help reduce electromagnetic interference and crosstalk, making UTP suitable for networking applications like Ethernet.

UTP stands for Unshielded Twisted Pair.
