Types of Shielded Ethernet Cables

F/UTP– Foiled/Unshielded Twisted Pair

Common in Fast Ethernet deployments, this cable will have a foil shield that wraps around unshielded twisted pairs.

S/UTP– Braided Shielding/ Unshielded Twisted Pair

This cable will wrap a braided shield around unshielded twisted pairs.

SF/UTP– Braided Shielding+Foil/Unshielded Twisted Pairs

This cable braids a shield around a foil wrap to enclose unshielded twisted pairs.

S/FTP– Braided Shielding/Foiled Twisted Pair

This cable wraps a braided shield around all four copper pairs. Additionally, each twisted pair is enveloped in foil.

F/FTP-Foiled/Foiled Twisted Pair

This cable encloses all copper pairs in foil. Additionally, each twisted pair is enveloped in foil.

U/FTP-Unshielded/Foiled Twisted Pairs

This cable only envelopes the twisted pairs in foil.

U/UTP-Unshielded/UnshieldedTwisted Pair

No sheathing is used. Standard Cat5e cable are examples of U/UTP cables.
