What should be paid attention to in the maintenance and management of optical cable communication lines

(4) Several elements that affect the normal operation of Optical Cable communication lines

(5) The cable is also susceptible to various external factors during operation, which can easily lead to a series of faults. The reasons for cable failure can be roughly divided into three types: natural factors, human factors and construction quality factors.

(6) Analysis of optical cable communications, any small faults will directly affect the safety of its operation, to the relevant enterprises to bring huge economic losses. Therefore, in the operation process of communication cable, it is necessary to pay satisfactory attention to these relevant elements, and adopt corresponding measures to eliminate potential security risks in a timely manner. As long as this can be used to improve the operating safety and stability of optical cable lines, and promote the development of China's communications affairs. Industry was further developed. Protection methods for communication optical cable lines

(7) Part of the needs of communication cable management regularly organize personnel to check the line. For some optical cables in the construction process, the need to pay more attention to remove and correct a variety of potential safety hazards in a timely manner. In the specific construction process, we also need to envelope the cable. Flammable, explosive and corrosive materials should be removed in time.

(8)The construction unit is required to set a project label in the cable location area. In the daily protection process, in order to prevent many problems such as land subsidence, it is also necessary to conduct regular soil cultivation and correction in the area of the cable location. In addition, repair personnel also need to repair the underground chamber and water line chamber of the cable site. The cleaning of the hydrogen ensures its drying and satisfactory ventilation, thus usefully preventing corrosion of the cable in harsh environments.

(9)The corresponding optical cable repair personnel also need to regularly view and repair the overhead optical cable, and need to make up for the hook in time to help prevent the occurrence of communication optical cable landing damage. In this process, protectors also need a junction box that can secure the overhead cable.

(10)Adjustment and check of Optical Fiber attenuation constant: in the normal operation process of optical fiber, it is often affected by various factors such as external temperature and self-aging, and the initial attenuation value of optical fiber will change greatly under the influence of various factors. When the attenuation constant of the cable exceeds 0.1db /km, it will directly affect the operating quality of the cable and the function of information transmission. Therefore, in the emergency repair process, if the need to reconnect the optical fiber, you should strictly control the joint loss within 0.2 db. In the process of optical cable modification and correction, the average loss of single-mode optical fiber should be controlled within 0.1 db.
