A kind of reel type optical unit optical cable and its manufacturing process

Abstract

The invention discloses a reel-type optical unit optical cable and its manufacturing process, comprising an optical unit and a jacket layer, the optical unit includes a reel-type optical fiber ribbon and an aramid fiber in the center, and the reel-type optical fiber ribbon is sequentially wrapped with resistance Water materials, cable ties, and sleeves, the manufacturing process steps are: 1. Make a number of optical fibers into optical fiber ribbons through a belt mould; Form an optical fiber column, and put it into the sleeve to form an optical unit after covering the water-blocking material and tying it; 3. Make a tape-type central tube optical cable or a layer-stranded optical cable, and have a mold with a resin press-in tube, The optical fiber difference between each layer of the optical fiber column is 6, the outer diameter of the 6-90-core optical fiber column is 636µm-2332µm, the number of layers is 1-5 layers, and the diameter of the optical unit is 1.4-4.8mm. The sleeve of the present invention The diameter is small, the optical fiber cable made is light in weight and small in diameter, the bending radius of the optical cable is small, and the construction and laying are easy. The mesh optical fiber ribbon can be welded at one time, and the construction is convenient.

Description

technical field

[0001] The invention relates to a roll-type optical fiber ribbon cable and a manufacturing process of the optical unit cable. Background technique

[0002] With the continuous development of urban construction and communication construction, the optical fibers required for optical cables are getting larger and larger. Generally, 245µm optical fibers are used for large-core optical cables with 144 cores and 12 cores per tube. One-to-one butt joint of optical fibers is usually connected to the 144-core optical cable connector, which takes several hours of construction time, and the optical cable structure is also relatively large, which is time-consuming and laborious to install and lay. With the development of communication construction, people have developed optical fiber ribbon cables, and at the same time developed an optical fiber fusion splicer, which can splice all the optical fibers of an optical fiber ribbon at one time, which makes the fusion of large...
