Main article: "Twisted pair § Cable shielding

Annex E, Acronyms for balanced cables, provides a system to specify the exact construction for both unshielded and shielded balanced twisted pair cables. It uses three letters - U for unshielded, S for braided shielding, and F for foil shielding - to form a two-part abbreviation in the form of xx/xTP, where the first part specifies the type of overall cable shielding, and the second part specifies shielding for individual cable elements.

Common cable types include U/UTP (unshielded cable); U/FTP (individual pair shielding without the overall screen); F/UTP, S/UTP, or SF/UTP (overall screen without individual shielding); and F/FTP, S/FTP, or SF/FTP (overall screen with individual foil shielding).

Edition 3[edit]

Edition 3, currently being prepared by "ISO/IEC JTC 1/SC 25 "Interconnection of information technology equipment", is a major revision of the standard which will unify several prior standards for commercial, home, and industrial networks, as well as data centers, and define requirements for generic cabling and distributed building networks.

The new series of standards will include six parts: [5][11]

ISO/IEC Standard Title Replaces Description
ISO/IEC 11801-1 Part 1: General requirements ISO/IEC 11801 Generic cabling requirements for twisted-pair and optical fiber cables
ISO/IEC 11801-2 Part 2: Office premises ISO/IEC 11801 Cabling for commercial (enterprise) buildings
ISO/IEC 11801-3 Part 3: Industrial premises ISO/IEC 24702 Cabling for industrial buildings, with applications including automation, "process control, and monitoring
ISO/IEC 11801-4 Part 4: Homes ISO/IEC 15018 Cabling for residential buildings, including 1200 MHz links for "CATV/"SATV applications
