Category 8.2 E20 LSFR0H S/FTP Cable


Siemon's Category 8.2 cable exceeds the transmission performance requirements of IEC 61156-9 up to 2000 MHz. This fully shielded cable supports 30-meter Class II as well as 100-meter class FA balanced cabling performance (ISO/IEC 11801-1 draft) to meet IEEE 802.3bq 25 Gb/s (25GBASE-T) and 40 Gb/s (40GBASE-T) applications in the data center. As part of a Class II twisted-pair cabling system which shares open and common specifications, interoperability and backwards compatibility are ensured with the reach to support a broad range of architectures for switch-to-server connections, including switches placed in top of rack (ToR), middle of row (MoR) and end of row (EoR). With an LSFROH cable jacket qualified for mechanical reliability in high temperature environments up to 75°C, Siemon's S/FTP Category 8.2 cable features individual foils around each pair and a high screen coverage outer braid to provide superior noise immunity and coupling attenuation performance.
