These RS PRO patch cables, also known as Ethernet patch cables, are made with Category 6 cables, commonly referred to as Cat 6 cables. They are electrical cables frequently used in office environments to connect computers to a network hub, router, or Ethernet switch. These RS PRO Cat 6 patch cables are designed for mechanical and electrical reliability and utilize high-quality materials. They provide a high-performance patch cable solution with a design feature that supports all cable applications in a single design. Low smoke and zero halogen, commonly referred to as LSZH or LSOH cables, they are used in areas where smoke development and toxic fumes could harm human health and critical facilities in the event of a fire. LSZH cables have an outer sheath that produces lower amounts of smoke and toxic fumes and does not emit acidic gases. These measures are particularly beneficial for employees, allowing for safe evacuation during a fire and enhancing the safety of firefighting efforts. They are foil twisted pairs (FTP) network cables, meaning the copper wires are twisted together and covered with a foil shield that reduces crosstalk and electromagnetic interference.
