The optical cable is manufactured by the outer cover of a single, multiple optical fibers or an external combination of optical fiber beams as an indicator of optical characteristics, environmental performance, and a cable structural entity suitable for mechanical characteristics. Mainly include belt structure, restraint structure, skeleton structure, twisted head structure and so on. Slowly applied to long-distance routes in the 1980s, and gradually began to use a single model optical fiber. Over the years, optical fiber cable technology has developed steadily for a long time.

Polyfiber cable

1 Features of optical cable

Compared with the copper cable up to now, the transmission effect of the optical cable is very large.

(1) Wide bandwidth and large communication capacity. The broadband that can use optical fiber is about 500 GHz, and the network transmission of 1-IOJb/s is very simple.

(2) The loss caused is very low, and the relay distance is long. The loss caused by the use of optical fiber transmission is very small. For the relay distance, the optical cable is longer than the cable.

(3) Optical fiber is an insulating material, which has strong resistance to electromagnetic obstacles.

(4) There is no interference called crosstalk, and it has good secrecy. Light waves can be simply transmitted through optical cables, and optical fibers hardly leak.

(5) The wire diameter is very thin and easy to lay.

(6) By using optical cables instead of cables, considerable metal materials can be saved.

However, we have also learned that the optical cable itself has certain shortcomings, such as low mechanical strength, fragile nature, low technical requirements, and difficulty in connection. Therefore, we need to analyze the construction specifications of optical fiber cable projects, and the quality of optical cable projects can be guaranteed.

As mentioned above, the rapid development of optical fiber in recent years has accelerated the construction of optical fiber projects. However, due to factors such as the inherent weakness of the optical fiber itself, the laying of optical cables has become difficult. If engineers have such problems in the laying process, if all of them affect the quality of the project, May affect the transmission of information. In this regard, we clearly stated the specifications for the construction of the radio and television light project, and the constructor must follow the project specifications to ensure the quality of the project.
