FTTH drop cable factory-Aixton

Ordinary ftth cable has a standard 8-shaped structure; two parallel strengthening cores, with an optical fiber in the middle; self-supporting leather cable adds a thick steel wire suspension wire to the structure of ordinary leather cable; generally speaking, self-supporting ftth The fiber optic cable is just an extra steel wire, and nothing else has changed;
The structure of each manufacturer of this kind of optical cable is different. But most of them are not metal reinforced cores, take butterfly ftth cable as an example. The cross section looks like a butterfly, so it is called. Both sides are leather wires and inside are reinforcements, and the middle is optical fiber.
1. Butterfly optical cables are divided into indoor and indoor (indoor) and outdoor. The prices of the two are quite different. The price of the outdoor type is about twice that of the indoor type. The price factor should be considered when making a specific design plan. In general, Ordinary optical cables (GYTA-G 652D) are still used outdoors, and indoor butterfly optical cables are used indoors, and the two are transitioned through fiber distribution boxes or splice boxes.
2. The butterfly optical cable has the characteristics of small curvature radius, light weight, relatively good bending resistance, easy fixing, and easy termination in the 86 terminal box.
3. There are two forms of butterfly fiber optic cable: non-metallic strengthening member and metal strengthening member. Considering the factors of lightning protection and anti-strong electric interference, the butterfly cable with non-metallic strengthening member should be used indoors.
4. Indoor butterfly optical cables have specifications such as 1 core, 2 cores, 3 cores, and 4 cores. Residential users should use single-core cables to access butterfly optical cables; business users can access butterfly optical cables according to 2--4 Core cable design.
The connection methods include cold connection and welding.
Cold splicing is to install the terminal by preparing the end face of the optical fiber and connect it with the flange head.
