What is the plastic optical fiber

Plastic optical fiber by a single fiber bundle (typical beam diameter of 0.25 to 1.5mm) form, usually PVC jacket. It can install in small spaces and can be bent a small angle.

Most of the plastic optical fiber are made ​​of the detection probe head with a screw-shaped or cylindrical, without making the other end of processing to facilitate the customers to use their cut. Banner's plastic fiber optic fiber is equipped with a knife. Unlike glass fiber, plastic optical fiber with high flexibility, the plastic optical fiber with a protective jacket for installation in reciprocating mechanical structure. Plastic optical fiber to absorb certain wavelengths of light, including infrared light, which plastic fiber can transmit visible light.

Compared with glass fiber, plastic optical fiber vulnerable to heat, chemicals and solvents.

On the radio and direct trans-glass fiber and plastic optical fiber both "single-root" - on the radio, there are "forked" - straight trans. Single fiber can transmit light from the emitter to the detection zone, or from the detection zone transfer to the receiver. Split fiber has two distinct branches, can transmit light and receive light transmission, respectively, so that infrared imaging sensors can either be launched by a branch of the light transmitted to the inspection area, while another branch will be reflected through the optical transmission back to the receiver.
Direct trans-glass fiber, and its detection at the fiber bundle is the first free layout. Direct trans-plastic optical fiber, the fiber bundles along the length of a fiber suffer a layout.

Special applications fiber

As the fiber by the use of environmental impact small and anti-electromagnetic interference, which can be used in some special occasions, such as: vacuum environment for the vacuum transmission fiber (VFT) and the explosive environment for the fiber. In both applications, special optical fiber installed in a special environment, leads received by a flange on the outside of the sensor, fiber, and a variety of flange sizes. Intrinsically safe sensor, such as NAMUR type sensors can be directly used for special or explosive environments.http://www.chinaopticcable.com
