Shielded systems support 10GBASE-T with headroom to spare

Shielded systems, such as Z-MAX 6A and Category 7A TERA, provide superior crosstalk and external noise immunity and support higher signal-to-noise margins than category 6A UTP cabling and are the ideal media for ensuring a seamless network upgrade to 10GBASE-T.

Furthermore, the physical robustness of the shield virtually eliminates the potential for alien crosstalk to be introduced in to the system as a result of poor installation practices and substandard MAC work.

  • Superior crosstalk immunity
  • Excellent external noise immunity
  • Higher signal-to-noise margins than category 6A UTP
  • Easier network upgrades to 10GBASE-T
  • Alien crosstalk difficult to introduce
