two copper wires that are twisted together are coated with an insulating coating that functions as a ground for the wires. Fiber-Optic Cable A type of cable that has a central glass core with cladding to prevent light loss and dielectric strengthening material which protects the core. They come in single, dual or multi-strand. Dark Fiber Dark fiber refers to unused fiber-optic cable. Often time’s companies lay more lines than what's needed in order to curb costs of having to do it again and again

organization. If the products installed have a UL mark that means the product has met the UL safety requirements. Using these products on a new build would make sense safety wise. UL 1666 applies to testing flame-propagation height for electrical and optical fiber cables installed in vertical shafts. This test makes sure that the flames will not spread up to another floor. The National Electrical Code article 110.26 calls for a minimum of 3’ to 4’ of clear workspace around all electrical equipment, so that
