Description

Novel low temperature resistant colored coated optical fiber

Technical Field

The utility model relates to the field of optical fibers, in particular to a novel low-temperature-resistant colored coated optical fiber.

Background

Optical fibers are short for optical fibers, and are fibers made of glass or plastic that can be used as a light conducting means. The transmission principle is "total reflection of light". 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. The optical cable is divided into: cable sheath, aramid fiber silk, buffer layer and optic fibre. Optical fibers are similar to coaxial cables except that the mesh shielding is not present. A glass core centered on the light propagation; the colored coated optical fiber is often subjected to a low-temperature environment during use, but the existing colored coated optical fiber has poor low-temperature resistance effect during use, so that the normal use of the optical fiber in the low-temperature environment is finally influenced.
