Optical cable communications technology (optical fiber communications) from the optical communication stand out, has become one of the main pillars of modern communications, in the modern telecommunications network plays a pivotal role. Optical cable communication as a new technology, its rapid development in recent years, the application of a wide range of communications is rare in the history of the world is also an important symbol of the new technological revolution and the future information society in a variety of information transmission tools.

1.optical cable The reason why the rapid development of communications, mainly because it has the following characteristics:

(1) communication capacity, transmission distance; a optical cable potential bandwidth of up to 20THz. With such a bandwidth, just a second or so, you can transfer all the ancient and modern Chinese and foreign text information is completed. The current 400Gbit / s system has been put into commercial use. Optical cable loss is very low, in the vicinity of the optical wavelength of 1.55μm, quartz optical cable loss can be less than 0.2dB / km, which is lower than any current transmission medium loss. Therefore, no relay transmission distance of up to dozens, or even hundreds of kilometers.

(2) signal crosstalk small, good security performance;

(3) anti-electromagnetic interference, good transmission quality, electrical communication can not solve a variety of electromagnetic interference problems, only optical cable communication from a variety of electromagnetic interference.

(4) optical cable Small size, light weight, easy to lay and transport;

(5) rich sources of materials, environmental protection is good, is conducive to saving non-ferrous metals copper.

(6) no radiation, it is difficult to eavesdrop, because the optical cable transmission of light can not run out of optical cable.

(7) cable adaptability, long life.

(8) texture brittle, poor mechanical strength.

(9) optical cable cutting and connection requires some tools, equipment and technology.

2. use of optical cable

(1) professional use. In the professional use, including submarine cable, high voltage tower on the empty cable, nuclear power plant anti-radiation cable, chemical industry, anti-corrosion cable.

(2) general purpose. Optical cable from the house to the house of the process can be divided into empty, underground road, buried directly, between the pipeline laying, indoor use.

The above is a brief introduction to the features and uses of the optical cable. To learn more about the content of the optical cable, please pay attention to the official website of kingsignal.
