Single-tube high-fiber-count stainless optical unit production method and corresponding tooling structure thereof

Abstract

The invention provides a single-tube high-fiber-count stainless optical unit production method. The method is characterized in that optical fibers are shunted before entering an optical fiber conduit, thereby realizing perfect transition of the optical fibers from an optical fiber frame to a stainless steel tube, lowering the abrasion damage probability of the optical fibers, keeping the stability of a production process, and fulfilling the aim of producing high-fiber-count optical unit. The single-tube high-fiber-count stainless optical unit production method comprises the following steps: machining and molding a stainless steel tube in advance; introducing the optical fibers and grease into the stainless steel tube, wherein the optical fibers and the grease are introduced through the optical fiber conduit and a grease conduit respectively; before the optical fibers are introduced into the optical fiber conduit, a plurality of optical fibers are shunted in advance through a group of #-shaped rollers; after the plurality of optical fibers are partitioned into a plurality of equal parts, the shunted optical fibers are introduced into the optical fiber conduit through independent flow channels in corresponding #-shaped rollers. The invention further provides a tooling structure for producing single-tube high-fiber-count stainless steel optical units.

Description

Technical field [0001] The invention relates to the technical field of optical unit production, in particular to a method for producing a single-tube large-core stainless steel optical unit. The invention also provides a tooling structure for producing a single-tube large-core stainless steel optical unit. Background technique [0002] The existing stainless steel optical units for OPGW, OPPC and submarine cables have a single tube with a maximum of 48 cores or 60 cores. With the continuous advancement of technology, such optical units can no longer meet the needs of communication. By designing a multi-tube optical unit, although it can barely meet the communication needs, it is obviously inferior to other materials such as aluminum-clad steel monofilament due to the bearing capacity and electrical performance of the optical unit. How to design the maximum capacity cores of the single-tube optical unit fiber without any problems in the actual production process has become an urge...

Problems solved by technology

[0002] The existing stainless steel optical unit for OPGW, OPPC and submarine cable has a maximum of 48 cores or 60 cores per tube. With the continuous advancement of technology, this type of optical unit can no longer meet the needs of communication

Through the design of multi-tube optical unit, although it can barely meet the needs of communication, the load bearing and electrical performance of the optical unit are obviously inferior to other materials such as aluminum-clad steel monofilament

How to design the maximum number of fiber cores in a single-tube optical unit without any problems in the actual process production has become an urgent problem to be solved. At the same time, the use of multi-tube optical units increases the manufacturing cost. For the use of a single-tube light unit, the control of the excess length also has certain limitations
