Which company should I choose for flame-retardant optical cables in smart buildings
Plenum fiber optic cables are suitable for use in areas where the air is circulated and fires are difficult to control, so OFNP flame-retardant fiber optic cables are the best choice. Flame resistant cable may be deployed in-duct (conduit) or cable tray. When routing a cable within a building, you will also need to factor in fire prevention. These composite cables are specifically designed for radiation sensors and to withstand harsh environments encountered in nuclear power plants. As a manufacturer, we know that the chemical composition of the cable jacket (Plenum, Riser, or LSZH) is the most expensive part of the production BOM.
