Cat 7A S/FTP

Cat 7A S/FTP is the highest-bandwidth cable to 1,000 MHz: fully screened, LSZH, for backbone links and future-proof data centres. Supplied to order; the lead time is stated in the quote.

Cat 7A S/FTP is the highest-performing screened four-pair copper 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 / foam-skin PE) and wrapped in its own aluminium/polyester foil; the four foiled pairs are 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). Cat 7A meets Class FA to 1,000 MHz and the tight per-pair and overall screening gives the best insertion-loss and crosstalk headroom of the copper categories; cables of this construction are commonly tested well beyond 1,000 MHz (1,200–1,600 MHz), supporting higher-grade components and 25GBASE-T over short channels. It carries 10GBASE-T to 100 m with large margin, all lower Ethernet grades and Power over Ethernet to IEEE 802.3bt (Type 4). Class FA links are normally terminated on GG45 or TERA connectors (backward-compatible with RJ45 for lower classes). 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.
