1. Why install optical cables?
At coal mine operation sites, due to terrain restrictions and difficult construction, wireless communication is generally used. However, its signals are subject to large electromagnetic interference, and the reliability of signals and communications cannot be guaranteed. In comparison, optical cable communication signals have low interference, good anti-interference performance, large bandwidth, fast speed, safety and reliability. Therefore, it is highly necessary to install optical cables in coal mine operations.
2. Types and technical requirements of optical cables
Currently, there are two types of optical cables used in coal mine shafts: single-mode optical cables and multi-mode optical cables. When selecting optical cables, you need to select a suitable optical cable based on the underground environment and the required communication distance. At the same time, there are many technical requirements for optical cables, such as the voltage resistance, tensile strength, optical transmission performance, etc. of the optical cable. These technical requirements need to be considered when purchasing and installing fiber optic cables.
3. Installation location and wiring method
The installation location and wiring method of optical cables have a great impact on the quality and reliability of underground communications. In order to reduce damage to optical cables during transportation, installation, and use, it is necessary to choose a safe and reliable installation location and a reasonable wiring method. Generally speaking, optical cables can be installed on the shaft walls, derricks, shafts, etc. of shafts, or they can be installed by laying optical cable troughs. The wiring method needs to comply with technical requirements such as bending radius and longitudinal compression.
4. Protection of optical cables
Optical cables also need to be protected during use to reduce damage and maintenance costs. Generally speaking, there are two main ways to protect optical cables: one is to use a protective tube, in which the optical cable is placed in the protective tube and fixed with anchors. The other is to directly use the well wall for protection. When selecting protection measures, the reliability of the optical cable and the actual situation need to be considered comprehensively.
