Optical Fibre Cables

A fiber-optic cable is made up of extremely thin strands of glass or plastic known as optical fibers; one cable can have as few as two strands or as many as several hundred. The optical fibers are typically coated with a protective layer followed by a final outer jacketing designed to protect the multi-stranded cable as a whole. Fiber-optic cables are used to transfer information via pulses of light in different applications such as long distance telecommunication or providing high speed data connection.
