Category 7 cable, more frequently known as a Cat7 or Cat-7 cable, is a form of high-end data transfer patch cable used in delivering the core infrastructure of wired Gigabit Ethernet setups.

Capable of delivering certain data transfer rates reliably over a defined range of distances
Built to meet stringent criteria around crosstalk and system noise blocking
Able to cope with a range of potentially problematic environmental hazards as it delivers these speeds
Be guaranteed for a minimum lifespan in continual operation

The Belden cat7 cable is Low Smoke Zero Halogen, commonly termed as LSZH or LSOH. These cables are used where smoke emission and toxic fumes could cause harm to human health, as well as to essential equipment in the event of a fire. LSZH cables have an outer sheath material which produce lower levels of smoke and toxic fumes, and no acid gases. These are particularly beneficial to personnel exiting safely during a fire, as well as increasing the safety of the firefighting operation.
