example 1

[0072] Such as figure 1Shown is a cross-sectional view of a 24-fiber self-supporting stainless steel center bundle tube cable with four strength elements, which includes strength elements, optical fibers, filler compound, stainless steel tube, outer jacket, hanging neck, and suspension wires. The optical fiber is the B1.3 optical fiber specified in YD / T 9771.1-2008. The number of cores of the optical fiber is 24, of which 12 cores are colored according to the full color spectrum, and the thickness of the colored layer is 5 μm. The remaining 12 cores are colored by the full color spectrum Spray black monochrome ring; the filling compound is thixotropic water-blocking ointment; the outer diameter of the stainless steel tube is Φ2.9mm, and the thickness of the stainless steel tube is 0.18mm; the outer sheath is black high-density polyethylene material and Add a special compatibilizer; the reinforcement is phosphating steel wire, the number is four, symmetrically distributed aroun...

example 2

[0074] Such as Figure 4 Shown is a cross-sectional view of a two-strength, non-self-supporting, 24-fiber stainless steel center bundle tube cable consisting of optical fiber, filler compound, stainless steel tube, strength member, and outer jacket. The non-self-supporting stainless steel central beam tube optical cable removes the hanging neck and hanging wire on the basis of the self-supporting stainless steel central beam tube optical cable. The production process follows the self-supporting stainless steel central beam tube optical cable process, but it needs to be removed during production. The mold of the self-supporting optical cable, and the metal hanging wire pay-off device, the non-self-supporting stainless steel central beam tube optical cable has a circular cross-section and an outer diameter of Φ7.0mm. Other technological processes are the same as above.

[0075] The full performance test results of the optical cable of the present invention are given below, as s...

Abstract

The invention discloses a stainless steel GYXTW type optical cable and a manufacturing method thereof. The method includes the following steps: 1. coloring optical fibers; 2. moulding a stainless steel pipe optical fiber unit; 3. manufacturing the stainless steel GYXTW type optical cables; and 4. testing overall properties of the optical cables. The optical cable herein includes an external sheath and suspension wires which are connected through a neck. The external sheath is provided thereon with at least two reinforcement pieces and is provided therein with a stainless steel pipeline. The stainless steel pipeline is provided therein with a filling composite and optical fibers. Each suspension wire is provided therein with a steel strand which is made by twisting galvanized steel wires. The stainless steel GYXTW type optical cable uses stainless steel GYXTW, has the advantages of small external diameters, high strength and strong biological protection. The stainless steel GYXTW type optical cable can effectively address large pollution in the environment due to manufacturing optical cables in the prior art, prevents additives from being washed away by rainfall or other environment factors after construction and ensures protection effects of the optical cables.

Description

technical field [0001] The invention belongs to the technical field of optical fiber and cable, and relates to a stainless steel central beam tube type optical cable and a manufacturing method thereof. Background technique [0002] With the rapid development of optical communication technology, fiber optic cables are frequently used in various complex environments. my country has a vast territory and a complex ecological environment. The frequency of fiber optic cables being damaged by wild creatures is gradually increasing, including rodents (squirrels, mice, etc.) etc.), insects (cicadas, ants, cockroaches, etc.) and birds (woodpeckers, crows, etc.). Optical cable manufacturers have launched a variety of protective optical cables with protective properties for different regions and different application environments to meet the needs of users. [0003] Protective optical cables are mainly considered from two aspects of physical protection and chemical protection. Chemical...
