Description

Technical Field

[0001] The utility model belongs to the technical field of optical cable equipment, and in particular relates to a measuring pipe connection tool used for connecting stainless steel optical units of submarine optical cables. Background Art

[0002] As an important component of submarine optical cables, the quality and performance of stainless steel optical units are crucial to the transmission efficiency and stability of the entire optical cable. Submarine optical cables are mainly used for cross-sea and cross-ocean communications, and the required cable length is basically more than 100 kilometers. Such long-distance transmission places extremely high demands on the material, process and design of the optical cable.

[0003] In the production process of stainless steel pipes, due to the limitation of the length of optical fiber, there may be the risk of optical fiber breaking or steel pipe breaking during the production process. Each break is an extremely serious problem for submarine optical cables. The submarine optical cable is located in an extremely harsh environment with factors such as seawater corrosion, ocean current impact, and complex seabed terrain. Therefore, the protective layer of the optical cable must have a high degree of reliability and stability. If there are difficult-to-repair faults in the stainless steel pipe during welding, these faults may cause the optical cable to break during operation, seriously affecting the quality and stability of communication.

[0004] Therefore, in the process of submarine optical cable production and use, it is inevitable to connect optical units of a certain length and repair damaged optical units. Pipe connection and other connection methods can be used as a repair solution to solve the problem of stainless steel pipe breakage.

[0005] The traditional connection method is: the sleeve to be connected is set on the outside of the outer tube of the two groups of connecting optical fibers to be connected, and then the sleeve to be connected is pressed inward by a pipe clamp or other tools to achieve crimping of the outer tubes of the two groups of connecting optical fibers to be connected. The crimping of this method depends on personal feeling, and the embossing is deep or shallow. If it is too deep, it is easy to damage the steel pipe and cause the outer pipe to break. If it is too shallow, the mechanical properties are not strong and the water tightness is not good, and the use effect is not good. Utility Model Content
