Application of communication armored optical cable Date: 2018-02-01 Optical fiber communication refers to the use of coherent and directional excellent laser beam as carrier to carry information, and the optical cable as a transmission medium to achieve information transmission, to achieve communication purposes of a new communication technology. Fiber optic cable is a single glass fiber, close to the core of the cladding layer, a coating layer and a plastic cover. The core and cladding are composed of two different optical properties of the medium, the internal medium refractive index of the light is higher than the refractive index of the medium around it, so when the beam from the high refractive index on the side of...

Security monitoring fiber applications. Date: 2018-02-01 Security monitoring System is the application of optical fiber, coaxial cable or microwave transmission of the video signal in its closed loop, and from the camera to the image display and recording constitute a separate complete system. It can be real-time, image, real reflection of the monitored objects, not only greatly extending the human eye observation distance, and expand the human eye function, it can be in the harsh environment instead of manual long-time monitoring, so that people can see the actual occurrence of the scene is monitored and recorded by the recorder. At the same time alarm system equipment to the illegal intrusion alarm, generated alarm signal input alarm host, alarm host trigger ...

Application of fiber optic cable sensor in power new energyDate: 2018-02-01 The application of optical fiber sensor in new energy temperature measurement is mainly based on the characteristics of high bandwidth and strong anti-jamming ability, and no matter how bad the condition is, the problem can be detected and repaired in time. With the help of optical fiber sensor to monitor the surface temperature of power cable and the temperature of cable dense area, the temperature of cable interlayer and cable tunnel in power plant and substation area should be measured and monitored in the process of running monitoring system. To effectively monitor the cable, the temperature measurement of optical fiber and cable surface to fit, read the effective cable surfa...
