Technique for producing laser welding stainless steel tubes cladded optic fiber unit

Abstract

The ivnention relates to the product line suitable to the optic fiber unit with the stainless steel tubes packed for optic fiber composite aerial earth wire OPGW and submarine fiber capable SOFC as well as its producing technique. The production line includes following sections: The feeding reel for long length of optical fiber, the oil charge, the unreeling steel tape, the longitudinal covering and welding etc. The producing steps are included as follows. unreeling optical fiber the optical fiber is introduced into the stainless steel tube, filling in salve to reduce friction force, unreeling steel tape, longitudinal covering type welding stainless steel tape drawing welded stainless steel tube containing fibers, traction and the residual length control, taking the optical fiber up.

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...

Problems solved by technology

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 distribution of optical fiber in the tube in the optical fiber unit, so that the effective life of the optical fiber cannot be guaranteed. In addition, due to the limitations of existing equipment, existing products cannot meet the requirements of customers for ultra-long and large-core optical fiber units.
