Optical fiber cable is safe for data transfer. It is a coating made of plastic or other materials , which protects the fiber from moisture , abrasion , sprains and other natural disasters. With optical fiber cable, huge amounts of data can be transmitted at light speeds over a short distance. In this system data loss is less in data transport. Optical fiber cable is widely used in telecommunication. It is also being used for lighting , sensors and photo editing. Due to the high electrical resistance, this cable can be used with high voltage electrical equipment.
