Simplex Fiber Optic Cable is fiber optic cable that has a single optical fiber running through it. This fiber is tight buffered and surrounded with aramid yarn for strength and protection. Both of these are then covered with a PVC outer jacket. The outer jacket is most commonly 1.6mm, 2mm or 3mm in diameter. Simplex fiber optic cable is very often used to make cable assemblies (patch cables or jumpers) that may be used to connect equipment or for testing a fiber optic link.
