What are the structures of optical fiber cable products?
Ordinary optical cables have a standard 8-shaped structure; two parallel reinforcing cores, with an optical fiber in the middle; The self-supporting leather optical cable adds a thick steel wire suspension wire to the structure of the ordinary leather optical cable; generally speaking, the self-supporting leather optical cable only has one more steel wire, and nothing else has changed;
Each manufacturer of this type of optical cable has a different structure.
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. There are two types of butterfly optical cables: indoor and indoor (indoor) and outdoor. The price difference between the two is large. The price of the outdoor type is about indoor 2 times the price of the model. Price factors should be considered when making specific design plans. Under normal circumstances, ordinary optical cables (GYTA-G 652D) are still used outdoors, and indoor butterfly optical cables are used indoors. Both pass through fiber distribution boxes or joint boxes. transition.
2. Butterfly optical cable has a small radius of curvature, is light in weight, has relatively good bending resistance and is easy to fix. It is used in 86 terminals Features include easy termination inside the box.
3. Is there anything wrong with the butterfly-shaped home optical cable? There are two forms: metal reinforced components and metal reinforced components. Taking into account factors such as lightning protection and strong electric interference prevention, non-metallic reinforced butterfly optical cables 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 can access butterfly-shaped inlets. Household optical cables should be single-core cables; business user access butterfly optical cables can be designed as 2-4 core cables.
The connection methods include cold splicing and welding.
Cold splice is to prepare the optical fiber end face, install the terminal block and connect it with the flange head.
