Stainless-steel-pipe optical fiber unit joint and connection method thereof

Abstract

The invention discloses a stainless-steel-pipe optical fiber unit joint and a connection method thereof. The stainless-steel-pipe optical fiber unit joint comprises a stainless-steel-pipe optical fiber unit, an inner insertion pipe and an outer casing pipe. An optical fiber with a certain length is exposed from a port to be connected of the stainless-steel-pipe optical fiber unit. The inner insertion pipe is inserted into the port to be connected of the stainless-steel-pipe optical fiber unit. Polishing processing is performed on two end pipe orifice edges of the inner insertion pipe. The outer casing pipe sleeves the stainless-steel-pipe optical fiber unit. The optical fiber unit joint is made through the above mode. By using the joint and the method in the invention, situations that the optical fiber is scratched or cut off during a joint making process can be avoided; connecting quality is high; the optical fiber in the optical fiber unit after connection can be well protected; laying construction and maintenance of a submarine optical cable with a long length or a photoelectric composite cable are convenient.

Description

technical field [0001] The invention relates to the field of optical fibers, in particular to a stainless steel tube optical fiber unit connector and a connection method thereof. Background technique [0002] With the global economic integration and the development of marine economy, submarine optical cable communication and information flow surge, which provides a broad market space for submarine optical cable transmission systems, and also promotes the further improvement of submarine communication system technology. The quality and use requirements of submarine optical cables in the world Also getting higher and higher. At present, the optical fiber units used in submarine optical cables are generally stainless steel tube optical fiber units. Due to the length of optical fibers and the limitations of optical unit production equipment, the length of a complete optical fiber unit is generally 25~50km, which cannot meet the requirements for manufacturing large-length submari...

AI Technical Summary

Problems solved by technology

At present, the optical fiber units used in submarine optical cables are generally stainless steel tube optical fiber units. Due to the length of optical fibers and the limitations of optical unit production equipment, the length of a complete optical fiber unit is generally 25~50km, which cannot meet the requirements for manufacturing large-length submarine optical cables or Requirements for Optical Composite Cables

In order to make a large-length submarine optical cable or a photoelectric composite cable, two or more optical fiber units are usually connected by using the optical fiber unit splicing method. However, the existing connection method is easy to scratch or cut the optical fiber, and The connection quality is not high and cannot meet the demand
