In a single-band optical fiber communication system, the optical fiber is usually affected by the terminal equipment, which cannot fully express the characteristics of broadband, but through the optical fiber communication transmission technology, this defect can be perfectly solved. The broadband and high-capacity characteristics of optical fiber communication are of great significance to the transmission of information, and can meet the development needs of future broadband integrated services.
Compared with other transmission media, the loss of practical silica fiber can be below 0.2dB/km, which is much smaller than that of other media. Even if non-quartz fiber is used in the future, the damage value will be around 10-9dB/km. The low-loss feature of optical fiber determines that optical fiber communication can achieve long-term relay distance. In the actual construction process, the cost of the communication system can be greatly reduced, which is conducive to improving the stability and reliability of the system.
Optical Fiber Communication
The material of the optical fiber has insulating properties, and is weakly affected by lightning, ionosphere, etc., and can also resist the interference caused by industrial electrical equipment such as electrification equipment and high-voltage equipment to a certain extent. It can be used for parallel erection with high-voltage transmission lines, or with The power conductors are combined to form a composite optical cable for communication transmission. The good anti-interference performance of optical fiber determines that it can be widely used in military, electrical and other fields.
In the process of traditional communication transmission, the information carried by the carrier is very easy to be stolen and leaked, so the information security effect of traditional communication transmission is poor. In the optical fiber communication transmission process, there is no interference phenomenon, and it is difficult for information to leak from the optical fiber. When the light wave is turning, it is easy to leak because the bending radius is too small, but its intensity is also very weak. For this problem, it can be eliminated by applying a matting agent, which can not only realize the confidentiality of information, but also meet the problem of shielding crosstalk interference.
The inner core radius of the optical fiber is about 0.1mm, which is 1% of the single-tube coaxial cable. The feature of low wire diameter makes the entire transmission system occupy a small space, which has the advantages of saving underground pipeline resources and reducing floor space. In addition, the optical fiber is made of glass, which is extremely light in weight, and the weight of the optical cable formed is also small.
It is still recommended to use products such as optical fiber and cable that meet the standards, and the quality is guaranteed. Of course, we also need to make comparisons in terms of cost performance. ZR Cable optical fiber manufacturers are worthy of the trust of the majority of users.
