Explanation of the structure of optical cable sheathed cables. Ordinary sheathed cables have a standard figure-8 structure; two parallel reinforcing cores with an optical fiber in the middle; self-supporting sheathed optical cables add a thick cable to the structure of ordinary sheathed cables. Steel wire suspension wire; Generally speaking, the self-supporting leather optical cable only has one more steel wire, and the other components remain unchanged;
The structure of each manufacturer of this type of optical cable is different.
But generally it is not a metal reinforced core, take butterfly-shaped leather optical cable as an example.
The cross-section shape is like a butterfly, hence the name.
There are reinforcing parts inside the leather cord on both sides, and an optical fiber in the middle.
1. Butterfly optical cables are divided into indoor and outdoor (indoor) There is a big price difference between the two. The price of the outdoor type is about twice that of the indoor type. Price factors should be considered when making specific design plans. Under normal circumstances, ordinary optical cables (GYTA-G 652D) are still used for outdoor use, and for indoor use For indoor butterfly optical cables, the two are transitioned through a fiber distribution box or a splice box.2. Butterfly optical cable has a small radius of curvature, is light in weight, has relatively good bending resistance, is easy to fix, and is easy to terminate in an 86 terminal box.
3. Butterfly-shaped home optical cables come in two forms: non-metallic reinforced components and metal reinforced components. Taking into account factors such as lightning protection and strong current interference, butterfly optical cables with non-metallic reinforced components should be used indoors.
4. Indoor butterfly optical cables are available in 1-core, 2-core, 3-core, 4-core and other specifications. Residential users should use single-core cables to access butterfly-shaped home optical cables; business users should use butterfly-shaped optical cables to access the home. Optical cables can be designed as 2--4 core cables.
