Cat 6A S/FTP is the rugged 10G cable: a foil per pair with a braided overall screen, LSZH, for the tougher network environments. Supplied to order; the lead time is stated in the quote.

Cat 6A S/FTP is a fully screened four-pair Category 6A data installation cable for structured building cabling, supplied on a reel for horizontal permanent links. Each of the four pairs is built from two solid bare-copper AWG23 conductors insulated with polyethylene (PE) and wrapped in its own aluminium/polyester foil; the four foiled pairs are then enclosed by an overall braid of tinned copper wires under a low-smoke zero-halogen (LSZH) outer sheath (S = screened overall braid, FTP = foiled twisted pairs). The per-pair foils suppress pair-to-pair crosstalk while the overall braid adds a robust common screen that greatly reduces alien crosstalk, improves immunity to electromagnetic interference and reduces its emission, making it the preferred Category 6A cable for high-density bundles, industrial and EMI-exposed environments. It delivers Class EA performance to 500 MHz, supports 10GBASE-T to 100 m, all lower Ethernet grades and Power over Ethernet up to IEEE 802.3bt (Type 4), and terminates on screened RJ45 modules. The LSZH sheath (CPR Dca or B2ca) suits indoor routing in public buildings (the required class depends on the building use and the type of space, Bbl table 4.42); a PVC-sheathed Eca variant is offered for less demanding environments. A lighter foiled-pair U/FTP variant is available where an overall braid is not required.

Cat 6A10 GigabitS/FTP

Also known as: screened network cable · 10 gigabit cable

Applications

  • 10GBASE-T in industry and heavily loaded environments.
  • Routes with high EMC demands and mechanical stress.

What to look out for

  • Braid plus foil only makes sense with screened jacks and an earthed patch panel.
  • For Class F/FA choose Cat 7 or Cat 7A.

Which one do I choose?

Cat 6A S/FTP or Cat 7 S/FTP?

Cat 6A S/FTP

  • Class EA, 500 MHz
  • AWG 23, LSZH sheath

Cat 7 S/FTP

  • Class F, 600 MHz
  • AWG 23, LSZH sheath

On paper they are very similar: both have a foil around each pair, a tinned copper braid, AWG 23 conductors and an LSZH sheath. Cat 7 is specified up to 600 MHz (Class F), Cat 6A up to 500 MHz (Class EA). You only achieve Class F with GG45 or TERA connectors; with RJ45 the link stays Class EA. If you work with RJ45, Cat 6A S/FTP is the logical choice.

Cat 6A S/FTP or F/FTP?

Cat 6A S/FTP

  • tinned copper braid
  • more robust

F/FTP

  • second foil with drain wire
  • no braid

Both have a foil around each pair; the difference is the screen around them. S/FTP has a tinned copper braid, F/FTP a second foil with a drain wire. The braid makes S/FTP more robust and better against low-frequency interference. Choose S/FTP for industry and routes with high EMC requirements and mechanical load; elsewhere F/FTP is sufficient.
