high-speed data transmission, especially in environments where stability and large bandwidth are required.<\/p>\n<p>It is an upgrade to the Cat6 standard, offering higher transmission rates and greater immunity to interference.<\/p>\n<p>Cat7 cables are specified by the ISO\/IEC 11801 standard, which supports network rates up to <a href=\"https:\/\/mvslinks.com\/pt\/product-category\/10g-modules\/\" target=\"_blank\" rel=\"noopener\">10 Gbps<\/a> and is suitable for longer transmission distances (up to 100 meters).<\/p>\n<p>The Cat7 cable uses the STP (Shielded Twisted Pair) structure, in which each pair of twisted pairs has an independent shielding layer, which allows it to maintain good performance in environments with strong electromagnetic interference (EMI).<\/p>\n<p>&nbsp;<\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_is_the_cat7a_cable\"><\/span><strong>What is the
