The manufacturer of optical fiber filling paste tells you the purpose of optical fiber

Optical fiber communications technology stands out from optical fiber communication, has become one of the key supports of contemporary communication, and plays a vital role in contemporary China's mobile broadband. Optical fiber filling paste manufacturers believe that optical fiber communication, as a new technology, has a rapid development trend and wide application in recent years. It is not only rare in the history of communication, but also a key symbol of the global scientific and technological revolution and a key special tool for transmitting all kinds of information content in the information society in the future.

Optical fiber is the general name of optical waveguide. Optical fiber communication is a kind of communication mode in which light wave is used as information content medium and optical fiber is used as transmission medium. From the basic principle, the basic chemical factors constituting optical fiber communication are optical fiber, lamp source and optical detector. In addition to the classification of optical fiber according to the production and manufacturing process, raw material composition and electronic and optical characteristics, in application, optical fiber is often classified according to its main purpose, which can be divided into communication optical fiber and sensor optical fiber. The transmission mode of optical fiber is divided into two types: universal and special. The functional component optical fiber refers to the optical fiber used for light wave enlargement, plastic surgery, sound splitter, memory overclocking, deployment and optical oscillation, and often occurs in the form of a certain type of functional components. Optical fiber communication tends to develop rapidly. The key reason is that it has the following characteristics:

(1) Large communication volume and long transmission distance; The potential network bandwidth of an optical fiber can reach 20thz. With that kind of network bandwidth, the transmission of all text materials from ancient times to the present can be completed in only one second. At this stage, 400gbit / s system has already invested in commercial service applications. The loss of optical fiber is very low, and the wavelength of light is 1.55 μ M around, the loss of quartz fiber can be less than 0.2db/km, which is lower than that of all transmission media at this stage. Therefore, the transmission distance without wireless relay can reach tens or even up to 100 kilometers.

(2) Low data signal crosstalk and good safety performance;

(3) The anti-interference signal and transmission quality are good. Electrical communication can not deal with all kinds of interference signals. Only optical fiber communication will not be affected by all kinds of interference signals.

(4) The optical fiber has small specification and light weight, which is conducive to laying and transportation;

(5) The raw materials are rich and colorful, and the ecological environment is well protected, which is beneficial to saving the rare metal copper.

(6) Without radiation, it is difficult to monitor, because the light wave transmitted by the optical fiber cannot run out of the optical fiber.

(7) Optical cable has strong adaptability and long service life.

(8) Brittle material and poor impact toughness.

(9) The disconnection and continuation of optical fiber must be provided with certain special tools, machinery and equipment and technology.

(10) Separation and coupling are not convenient.

(11) The bending radius of optical fiber cable shall not be too small (> 20cm)

(12) There are difficult problems in power supply system.
