The performance of plastic optical fiber research focuses on attenuation, dispersion, and thermal stability. Let's take a look at the performance of plastic optical fibers with Inline Closure manufacturer.

Attenuation
The attenuation of plastic optical fibers is mainly limited by the absorption loss and dispersion loss of the core plastic material. People use plastic materials with low refractive index and low isothermal compression rate and reduce structural defects by stabilizing plastic optical fiber manufacturing process to obtain small scattering loss of plastic optical fiber, while absorption loss of plastic material is absorbed by molecular bond stretching vibration. And caused by electronic jump absorption.

2. Bandwidth
Plastic optical fibers used as short-distance optical transmission media can be classified into two types according to their refractive index distribution shapes: step-index distribution plastic fibers and gradient-index distribution plastic fibers.

The step-index distribution plastic optical fiber repeatedly reflects the human light due to the inter-mode dispersion, and the emitted waveform is broadened relative to the human-shooting waveform, so the transmission bandwidth is only tens to hundreds of MHz·km. The fluorinated gradient refractive index distribution plastic fiber is selected from low-dispersion materials, and the refractive index distribution index can be selected as 2.07 to 2.33 in the wavelength range of 0.85-1.3 μm by means of optimized gradient refractive index distribution. The inter-mode dispersion is suppressed, and the effect of the emitted light wave on the broadening of the human light wave is controlled, and a plastic optical fiber having a gradient refractive index distribution with a transmission bandwidth of several hundred MHz·km to 10 GHz·km can be obtained.

3. Thermal stability
Since the plastic optical fiber is made of a plastic material, it will undergo oxidative degradation when it is operated in a high temperature environment. Oxidative degradation is formed by carbonyl, double bonds and cross-linking in the core material of the optical fiber. Oxidative degradation will accelerate the electronic transition, which will lead to an increase in fiber loss. In order to effectively improve the thermal stability of plastic optical fibers, the usual practice is: 1 use plastic materials containing fluorine or silicon to make plastic optical fibers; 2 select the working wavelength of the light source of plastic optical fibers to be greater than 660 nm, in order to obtain thermal stability of plastic optical fibers. Long-term reliability.

4. System application
The use of plastic optical fibers as a first transmission link in short-range communication optical transmission systems ensures that high-speed Internet interfaces deliver high-resolution image and data conversion in a fast, bidirectional, and clear manner. Broadband services that can be carried out by plastic optical fiber networks include interactive multimedia and distance learning. Especially because hydrogenated gradient-index plastic optical fiber has the advantages of low attenuation, high bandwidth, low price, good thermal stability, large core diameter, easy connection construction, etc., and high-speed data is successfully carried out by means of current commercial optical transceivers and switches. Image transfer, so hydrogenated gradient-index plastics will be the first transmission medium for next-generation short-range optical transmission systems.
