Description

High-efficient test equipment is used in optic fibre manufacturing

Technical Field

Background

Optical fiber is a short term for optical fiber, which is a fiber made of glass or plastic and can be used as a light transmission means. The principle of transmission is 'total reflection of light'. The university of chinese university in front hong kong high roll, which thus received the 2009 nobel physics prize, and georgea. Hockham, first proposed the assumption that optical fibers could be used for communications transmission, were packaged in a plastic jacket such that it could be bent without breaking. Generally, a Light Emitting Diode (LED) or a laser beam is used as a transmitter at one end of the optical fiber to transmit an optical pulse to the optical fiber, and a photosensor is used as a receiver at the other end of the optical fiber to detect the pulse.

In daily life, optical fiber is used for long distance information transmission because the transmission loss of light in optical fiber is much lower than that of electricity in electric wire, and the two terms of optical fiber and optical cable are usually mixed. Most optical fibers must be covered by several layers of protective structures before use, and the covered cable is referred to as a fiber optic cable. 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: optical fiber, buffer layer and coating. Optical fibers are similar to coaxial cables except that the mesh shield is absent. The center is the glass core of light transmission, and in the production process of the optical fiber, the test accounts for a large proportion, wherein the performances of the optical fiber, such as uniformity, defects, breakage, joint coupling and the like, are important indexes which all optical fiber manufacturers must measure before the optical fiber leaves a factory.
