Characteristics of fiber optic communication

1, broadband information capacity: fiber-optic communication capacity, and the transmission width of optical fiber than cable or copper wire width is much larger, but for single-wavelength fiber optic systems, due to the terminal equipment is very limited, often do not play out the advantages of the transmission width of the fiber. So the need for scientific technology to increase the transmission capacity.

2, low loss, long-distance transmission: fiber optic communication loss rate than ordinary communication loss rate is much lower, optical fiber is not only low loss, but also for long-distance communication, the longest communication distance can reach more than 10,000 meters, so fiber optic communication is more practical in the social network where the amount of information is more. And fiber optic communication is more cost-effective, with good security.

3, strong resistance to electromagnetic interference: optical fiber is mainly made of quartz as raw materials for the manufacture of insulator materials, this material is good insulation, and not easily corroded. The most important feature of fiber optic communication is the strong resistance to electromagnetic interference, and is not subject to natural sunspot activity interference, changes in the ionosphere and lightning interference, and will not be subject to man-made electromagnetic interference.
