Description

technical field

[0001] The invention relates to a production process of laser welding stainless steel tube optical fiber unit and a production line thereof, which relate to a production line and production process of stainless steel tube optical fiber unit suitable for optical fiber composite overhead ground wire OPGW and submarine optical cable SOFC. Background technique

[0002] The optical fiber unit used in the existing optical fiber composite overhead ground wire OPGW and submarine optical cable SOFC is mainly composed of a plastic tube PBT plus an aluminum tube. The optical fiber units used in optical fiber composite overhead ground wire OPGW and submarine optical cable SOFC are due to various factors such as: unreasonable restrictions on production process methods, inconsistent state of optical fibers in stainless steel tubes, such as uneven distribution of optical fibers in stainless steel tubes, insufficient ointment filling, etc. Factors lead to unreasonable distri...
