POF

Basic Information:

1. Name : Plastic Optical Fiber

2. Abbreviation :  POF

There are two main types of materials used to make POF: Polymer Polymethylmethacrylate (PMMA) and Perfluorinated polymers (PFP).

Performance indicators:
1,Attenuation

The attenuation of plastic optical fiber mainly depends on the selected material, scattering loss and absorption loss. To be used as communication-grade plastic optical fiber, a basic requirement is that the attenuation of PMMA plastic optical fiber should be low, preferably less than 180dB/km.

2. Bandwidth

Gradient-type plastic optical fiber is an optical fiber with a gradient distribution of refractive index, and its refractive index gradually decreases from the core to the cladding. As long as the formation of the gradient refractive index distribution is appropriate, you can obtain the inhibition of mode dispersion, to maintain a large numerical aperture, the control of the outgoing light wave relative to the effect of the spread of the human light wave. If the refractive index distribution is appropriate, then the material dispersion becomes the main factor in determining the transmission bandwidth. As long as the choice of materials pay full attention to the dispersion, to produce a bandwidth of several Ghz-km is completely feasible.

3, heat resistance

Most importantly, the heat resistance of plastic optical fiber is mainly determined by the performance of its components. Good heat resistance of the material composition, the decision of the plastic optical fiber has a relatively good heat resistance. To determine the heat resistance of the material indicators are glass transition temperature, Vicat softening point, heat distortion temperature and other indicators.

4, connectivity

Plastic optical fiber for communications mostly used in 1mm diameter fiber, quartz fiber is 8 to 20 times. Thick plastic optical fiber connection is much easier than quartz fiber.

Advantages:
Plastic optical fiber is lightweight, flexible and more resistant to damage (vibration and bending). Plastic optical fibers have excellent tensile strength, durability and take up little space. These advantages make plastic fiber optics particularly important for successful automotive applications. The interior of a typical luxury car consists of at least a few kilometers of copper wires and cables, adding significant weight and cost. The same is true for airplanes, trains and all other means of transportation.

Due to the large diameter and numerical aperture of plastic optical fibers, the light transmission capacity is high. Plastic optical fibers have a much higher bandwidth capability than copper transmission media (twisted pair and coaxial cable). The higher the frequency of transmission, the lower the cost of using plastic fiber.

Plastic optical fibers are easy to cut, route, bond, polish and otherwise process. Because of the large diameter, plastic optical fiber installation and connection to devices, light sources, detectors, etc. becomes easy and inexpensive, and these operations can be performed by non-experts. Preparing plastic optical fibers for connection takes less than a minute at most and requires no special tools. Even the simplest scissors can be used to cut plastic optical fibers. The plastic fiber optic transceiver module uses 650nm red light, which is very safe and visible to the user and makes it easy to determine whether the fiber optic connection is successful or not. In addition, plastic fiber optic connections are insensitive to dust and debris trapped on the end face.
