This document introduces Lapp Limited's product Unitronic® LAN STP/S 1.2GHz CAT.7 4x2x22AWG, which is a halogen-free high-frequency data transmission cable with individually screened pairs. The product meets the prEN 50288- 4-1, August 2000 (draft) and EN 50173 as well as ISO/IEC IS 11801 standards. The product is designed for Gigabit Ethernet 1000 BaseT, ATM 155/622 Mbit/s and other standards.
The Unitronic® LAN STP/S 1.2GHz CAT.7 cable is a halogen‑free, screened twisted‑pair (STP) Category 7 cable designed for high‑speed data transmission up to 1.2 GHz. It meets and exceeds the requirements of prEN 50288‑4‑1, EN 50173 and ISO/IEC 11801, making it suitable for Gigabit Ethernet, ATM and other high‑speed standards.
The cable construction includes solid bare copper 22 AWG conductors, cellular polyolefin insulation, individually screened pairs with aluminium/polyester foil, and an overall LSZH sheath. Electrical properties such as DC resistance, impedance, and velocity of propagation are specified, together with mechanical limits like minimum bending radius, temperature range, and pulling strength.
