Full 100M distance at 10GBASE-T ISO/IEC 11801 2nd Ed. Most commonly installed cable in Finland according to the 2002 standard EN 50173-1. Same construction as Cat5, but with better testing standards. Limited to 100m between equipment.Įnhanced Cat5. Superseded by Cat5e, but most Cat5 cables meet Cat5e standards.

Now mainly for telephone cables Ĭommon for current LANs. Not described in EIA/TIA recommendations. These cables are no longer made, but are still occasionally encountered in old buildings and in various external areas, commonly rural villages. However, such seals made future maintenance and changes more difficult. The cable termination in termination boxes were sealed with molten wax or epoxy resin to prevent the ingress of moisture which would seriously degrade the insulating properties of the paper insulation. This style of cable came into use in the late 19th century shortly after the invention of the telephone. The overall sheath of this type of cable was usually lead. Prior to the common use of polyethylene and other plastics for insulation, telephone twisted pair cable was insulated with waxed paper or cotton with a wax coating applied to the copper. This type of shielding helps prevent EMI from entering or exiting the cable and also protects neighboring pairs from crosstalk. Common names: fully shielded twisted pair, screened foiled twisted pair, shielded foiled twisted pair, screened shielded twisted pair, shielded screened twisted pair. Individual and overall shield (F/FTP, S/FTP, and SF/FTP) Individual shielding using foil between the twisted pair sets, and also an outer foil or braided shielding. This type of shielding helps prevent EMI from entering or exiting the cable. Common names: foiled twisted pair, shielded twisted pair, screened twisted pair. Overall shield (F/UTP, S/UTP, and SF/UTP) Overall foil, braided shield or braiding with foil across all of the pairs within the 100 ohm twisted pair cable. This type of shielding protects cable from external EMI entering or exiting the cable and also protects neighboring pairs from crosstalk. Common names: pair in metal foil, shielded twisted pair, screened twisted pair. Common shield construction types include: Individual shield (U/FTP) Individual shielding with aluminum foil for each twisted pair or quad.
