The product structure of outdoor covered optical cable. Ordinary covered optical cable has a standard figure-8 structure; two parallel reinforced cores with an optical fiber in the middle. The self-supporting covered optical cable adds an extra layer to the structure of ordinary covered optical cable. Thick steel wire suspension wire; generally speaking, the self-supporting leather cable only has one more steel wire, and nothing else has changed; 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 two types: indoor and indoor (indoor) and outdoor. The price difference between the two is large. The price of the outdoor type is about twice the price of the indoor type. Specific design plans are being made. Price factors should be taken into consideration. Under normal circumstances, ordinary optical cables (GYTA-G 652D) are still used outdoors, and indoor butterfly optical cables are used indoors. The two are transitioned through fiber distribution boxes or joint boxes.
2. Butterfly optical cable has a small radius of curvature and is light in weight , relatively good bending resistance, easy to fix, and easy to terminate in the 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 protection against strong electric 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.
