Mainly used where the terminal device density is very high, such as for the cabling of office, administration, and development buildings in the tertiary area (floor cabling). The cable length in the tertiary area (horizontal area, floor) should not exceed 100 m in accordance with ISO/IEC 11801 or EN 50173 (90 m cable duct + 10 m workstation). This LAN cable is designed for structured building cabling in accordance with EN 50173 and ISO/IEC 11801. It features S/FTP with copper braiding as overall shielding and pair shielding with aluminium composite foil. The outer sheath is made of halogen-free, flame-retardant compound, and the solid conductor is yellow (RAL 1021). It meets class F in the ISO/IEC 11801 standard, corresponding to CAT 7. This cable supports the transmission of digital and analogue data signals and is flame-retardant in accordance with IEC 60332-1-2, as well as passing the bundle fire test in accordance with IEC 60332-3-24. It is compatible with IEEE 802.3: 10/100/1000Base-T, 10GBase-T, IEEE 802.5: ISDN, FDDI, and ATM, and is suitable for cable sharing with IEEE 802.3at: PoE.
