Double-core butterfly optical cable production technology

Abstract

The invention discloses a double-core butterfly optical cable production technology. A suspension wire reinforcing piece, a plurality of optical cable reinforcing pieces and two optical fibers are let out; the relative position of the suspension wire reinforcing piece, the optical cable reinforcing pieces and the two optical fibers is determined; the suspension wire reinforcing piece, the optical fibers, the optical cable reinforcing pieces and thermoplastic resin pass through a plastic extruding machine, and the plastic extruding machine shapes the thermoplastic resin into an optical cable protection cover and packages the suspension wire reinforcing piece, the optical fibers and the optical cable reinforcing pieces in the protection cover so that a double-core butterfly optical cable can be generated; the double-core butterfly optical cable is cooled; the double-core butterfly optical cable is pulled and straightened. The technology is used for producing the double-core butterfly optical cable, the two optical fibers of the optical cable are independent and do not affect each other, and the abnormal probability is greatly decreased.

Description

technical field [0001] The invention relates to a production process of an optical cable, in particular to a production process of a double-core butterfly optical cable. Background technique [0002] An optical fiber is a fiber made of glass or plastic that acts as a means of transmitting light. Based on the characteristics of good confidentiality, high capacity and high speed of optical fiber, optical fiber has a wide range of applications in communication. [0003] The disadvantage of the traditional single-core butterfly cable is that if the fiber is broken, it is easy to cause the interruption of optical fiber communication. Therefore, in relatively large backbone transmission networks, dual-core optical cables are generally used. The purpose of using dual-core optical cables is due to the needs of equipment. use, or use one of the fibers as a spare fiber in case one of the fibers is abnormal. Commonly used twin-core optical cables are two optical fibers packed side by...

[0003] The disadvantage of the traditional single-core butterfly cable is that if the fiber breaks, it will easily cause the interruption of optical fiber communication. Therefore, in relatively large backbone transmission networks, dual-core optical cables are generally used. The purpose of using dual-core optical cables is due to the needs of equipment. use, or use one of the fibers as a spare fiber in case one of the fibers is abnormal

Commonly used twin-core optical cables are two optical fibers packed side by side in a plastic sheath, such as Figure 7 As shown, since the optical fibers in this kind of dual-core optical cable are close to each other, in addition to the abnormalities caused by the factors of the optical fiber itself, the extrusion, compression, bending and other conditions caused by the outside world will affect the two optical fibers at the same time.
