Embodiment 1

[0038] This embodiment provides a polyolefin sheathed optical fiber bundling process, and the process flow is as follows:

[0039] 12 channels of G.657A2 colored optical fiber are released by the active pay-off frame, the pay-off tension is 80g / channel, and after passing through the fiber splitting mold, it enters the stranding table, and the stranding table performs reverse stranding, and the stranding pitch is 600mm. The stranding angle is 180°, and the stranding direction is forward and reverse. After the stranded optical fiber bundle is positioned by the optical fiber positioning mold, it enters the powder coating box for coating, and then enters the extruder head for extrusion. The extruded material is polyolefin material, and the extrusion temperature is 140-175°C. After being covered with plastic, it enters the vacuum sizing device, and the inner diameter of the sizing mold is 1.30mm. After sizing, the plastic-coated optical fiber first enters the first hot water trea...

Abstract

The invention discloses a polyolefin plastic-coated optical fiber bundling process. The process comprises the following steps of: (1) releasing n paths of optical fibers (6<=n<=12) through an opticalfiber pay-off rack, and feeding the optical fibers into a stranding table for reversing stranding after the optical fibers pass through an optical fiber branching die; (2) positioning the stranded optical fiber bundle by an optical fiber positioning die, and allowing the stranded optical fiber bundle to enter a powder smearing box to be smeared with powder; (3) allowing the powder-coated optical fiber bundle to pass through an extruder head plastic shield prebalelling polyolefin sheath, and allowing the powder-coated optical fiber bundle to enter a vacuumizing sizing device for sizing the sheath; and (4) after the sized plastic-coated optical fiber is subjected to sizing through cold and hot water treatment, allowing the sized plastic-coated optical fiber to enter a traction wheel and a tension wheel in sequence, and allowing the sized plastic-coated optical fiber to be taken up by a take-up system. The polyolefin plastic-coated optical fiber bundling process can prepare an indoor wiring optical cable based on the micro beam tube, and the optical cable is simple in structure, light in weight, small in size and capable of meeting the requirement of the using environment of large-scale high-capacity building wiring optical cables.

Description

technical field [0001] The invention relates to the technical field of optical cable manufacturing, in particular to a polyolefin sheathed optical fiber bundle process. Background technique [0002] With the implementation of the "Broadband China" strategy, "triple network integration" and construction will be carried out in depth, communication construction will bring more new optical fiber application requirements, and various new wiring optical cables that meet the needs of indoor wiring will emerge as the times require, and The application is more and more extensive. Indoor optical cables are required for the integrated wiring system of intelligent buildings and the connection inside and outside of communication equipment. With the popularization of high-bandwidth multimedia applications such as digital TV, and the application of home information terminals, the demand for communication capacity and bandwidth of home digital equipment is also increasing, making the appli...
