CAT6A STP shielded network cables A Cat6a cabling system is higher performance than Cat6 (500MHz v 250MHz) and designed to support 10GBase-T over the full 100 metre, 4 connector channel. It is backwards compatible with Cat6 and Cat5e.10GBASE-T Ethernet1000BASE-TX Fast Ethernet1000BASE-T Gigabit Ethernet100BASE-TX Fast Ethernet10BASE-T Ethernet155/622 Mbps ATM4/16 Mbps Token Ring100VG-AnyLAN100Mbps TP-PMDMolded with bootsOur Category 6A cable, in accordance to the TIA/EIA 568-C.2 standard, is tested from 1 to 600MHz. This wide range of frequency is required to handle the frequencies at with 10GBase-T (10 gigabit Ethernet) operates. As a result of the higher frequencies utilized by 10GBase-T, alien crosstalk performance parameters are incorporated into the TIA/EIA standard for Category 6A cable and connectivity. Alien crosstalk occurs when signal from a cable jumps to an adjacent cable. Alien crosstalk, like crosstalk that occurs between the pairs within a cable, will have a detrimental impact on cable’s ability to send and receive data packets. Category 6A is the first cable category standard to include alien crosstalk performance parameters. Shielded cables eliminate the crosstalk!
