Category 8.2 E20 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 channels 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 middle of row (MoR) and end of row (EoR) deployments. With a 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.
