The fine optical fiber is enclosed in a plastic sheath so that it can be bent without breaking. Typically, a transmitter at one end of the fiber uses a light emitting diode or a beam of laser light to transmit a pulse of light to the fiber, and a receiver at the other end of the fiber uses a light sensitive element to detect the pulse. In daily life, optical fibers are used for long distance information transmission because the loss of light transmitted through optical fibers is much lower than the loss of electricity transmitted through electric wires. In general, the terms optical fiber and optical cable are to be confused. Most optical fibers must be covered by several layers of protective structures before use, and the covered cables are referred to as fiber optic cables. The protective layer and the insulating layer on the outer layer of the optical fiber can prevent the surrounding environment from damaging the optical fiber, such as water, fire, electric shock and the like. But common optic fibre is high temperature resistant flame retardant efficiency poor, can influence the normal use of optic fibre greatly under high temperature environment, and higher temperature probably causes the conflagration, greatly increased the potential safety hazard, seriously influence the performance of optic fibre, and because the influence that receives temperature variation can produce and retract, influenced the performance of optic fibre, and the phenomenon that can seriously wear and tear appears after the long-time use of optic fibre moreover, greatly reduced the life of optic fibre, thereby influence the normal use of later stage optic fibre, bring very big inconvenience for the user.
