Common FAQ GUIDE of Fiber Optic Cables

Types of fiber optic cables

There are three types of fiber optic cable, each with its own set of characteristics. Single-mode fibers have a narrow core and a large number of strands, and their index of refraction changes less than that of multimode fibers. Light travels in a straight line and has very little pulse dispersion. Single-mode fibers are the most common type of cable used in telecommunications, as telephone networks install millions of kilometers of them each year. Tight-buffered cable is generally used inside buildings, and loose-tube cable is used in most outside-plant installations in North America.
