what is fiber optic cable used for

What is optical cable used for?Optical cable is mainly composed of optical fiber (fine like hair of glass filament) and plastic protective sleeve and plastic skin, is the use of one or more fiber in the covering sheath as a transmission medium and can be used separately or in a group of communication cable components. It is mainly in order to meet the optical, mechanical or environmental performance specifications and manufacturing, in simple terms is to take the optical fiber as the carrier, with light wave as the transmission medium of optical fiber communication cable, namely optical cable. It is mainly used in the communication industry, such as telecom, mobile and China Unicom, and other operators. In addition, the field of radio and television will also use optical cable as the amount of transmission medium of radio and television network. At present, the operators mainly take materials, equipment annual shortlisted way, and have this right to shortlisted is at least the provincial level of the company, the city branch can only be selected in the provincial telecom and provincial mobile operators and other shortlisted manufacturers. So, how should optical cable choose goods? What are the cable models? Hemudu sorted out the type classification of optical cables.

What is the optical cable used for? What does the optical cable project mainly do?

Do we understand the function and type of optical cable? So, what is the optical cable project? What is the relationship with the cable? In fact, optical cable engineering is often said to be the network cabling project, according to the integrated cabling system engineering design specification GB 50311-2016 on the fiber and cable laying provisions: fiber and cable in the radiation process should follow the seven standards:

1. The user optical fiber and cable should be fused.

2. In the wiring equipment of the user's access point and the information wiring box, it is advisable to fuse the tail fiber. When the conditions of fusion are not available, the optical fiber connection device can be assembled on site.

3.The same type of optical fiber connection device should be used in each optical fiber link.

4. The use of metal reinforced core fiber optic cable, metal components should be connected to the ground.

5. The reserved length of indoor optical cable should comply with the following provisions: the reserved length of optical fiber and cable in the distribution cabinet should be 3m-5m; The reserved length of optical fiber and cable should be 1m - 5m at the distribution box on the floor; The reserved length of optical fiber and cable should not be less than 0.5m when the information distribution box is finally connected. When the fiber core of the optical fiber and cable is not terminally connected, the reserved length of optical fiber and cable construction should be retained.

6. The minimum static bending radius of optical fiber cable laying and installation should comply with the provisions of the following form.

Table of minimum static bending radius for optical fiber and cable laying and installation

Note: D is the outer diameter of the circular sheath at the core of the optical fiber and cable, and H is the height of the short axis of the flat sheath at the core.

7. There should be no connection point in the route where the optical fiber and cable does not lie.
