Stainless steel tube optical unit connecting process

Abstract

The invention discloses a stainless steel tube optical unit connection process, which comprises the following steps of stripping, tube insertion, welding, tube moving and wrapping, namely inserting one end of a first inner insertion tube into a connection port of a first stainless steel tube optical unit, pressing and fixing, sleeving a sleeve on the outer circle of the part, not inserted into the first stainless steel tube optical unit, of the first inner insertion tube, and welding the first inner insertion tube with the sleeve; inserting one end of a second inner insertion pipe into the connecting port of the second stainless steel pipe optical unit, and pressing and fixing the end of the second inner insertion pipe; welding the exposed end parts of the optical fibers at the end parts of the first inner insertion tube and the second inner insertion tube; the sleeve is moved outwards, so that the first inner insertion pipe and the second inner insertion pipe are sleeved with the sleeve at the same time; and wrapping the exposed part on the outer circle of the first inner insertion pipe by adopting a heat shrink tube. By means of the mode, the stainless steel tube optical unit connecting technology can effectively repair the damaged optical unit, and the length of the optical unit and the optical fiber communication performance are recovered.

Description

technical field [0001] The invention relates to the technical field of optical cables, in particular to a stainless steel pipe optical unit connection process. Background technique [0002] As a link between ocean-crossing communication and island communication transmission, submarine optical cable has the characteristics of super long length, large capacity, high reliability, and strong anti-interference, and plays an extremely important role in international communication. [0003] Submarine optical cables are mainly used in cross-sea and trans-ocean communications, and the length of optical cables required is basically in units of hundreds of kilometers. Due to the limitation of the length of the optical fiber itself and the production equipment of the optical unit, it is impossible to meet the needs of large-length submarine optical cables, and the optical fiber and optical unit of the submarine optical cable may break during the production process. Every break is fatal ...

AI Technical Summary

Problems solved by technology

For the repair or connection of submarine optical cables, a sleeve can be added to the original stainless steel tube optical unit to realize the connection of two stainless steel tube optical units, but the sleeve increases the local diameter of the optical unit, which affects subsequent construction and bending. needs to be improved
