Since 2003, some enterprises in China have started to produce SI-POF optical fibers. In recent years, such enterprises have gradually increased, and their performance has also been greatly improved, which can be close to Japanese products.
Chongqing Century Light is authorized by the Physical and Chemical Institute of China Plastic Optical Fiber Research Institute to produce commercial SI plastic optical fiber on a large scale with attenuation of 153dB/km. At the same time, it also proposes solutions for many industries. If you are interested, you can consult.
In addition, there are manufacturers such as Tianxin and Huaying.
The comparative advantages of plastic optical fiber and copper wire are more obvious:
1. No electrical interference: Plastic optical fiber has no electromagnetic interference, crosstalk and noise.
2. Electrical isolation: POF optical network equipment is electrically isolated.
3. Save space: The diameter of POF cable is at least 50% smaller than that of TP twisted pair, so the wiring takes up less space.
4. Light weight: POF is at least 4 times lighter than Category 5 line, so it can save freight.
5. Quick connection: the connection can be easily cut.
6. Reliable and durable: Plastic optical fiber can withstand greater vibration.
7. Convenient installation: Because crosstalk and noise suppression need not be considered, it is convenient to install.
8. The connectivity test is simple: just test the link insertion loss.
9. Confidentiality and security: POF optical cable is not easy to be eavesdropped.
