From the next few years, the development speed of wire and cable industry in China will be higher than the speed of development of the national economy, is expected to reach more than 10%. Especially the power lines and ADSS optical cableThe average annual growth of up to 15%, the momentum of rapid. In recent […]
Introduction: The nonlinear effect will cause additional loss and interference, deterioration of system performance. WDM high power optical system and optical fiber transmission along the long distance, therefore produce nonlinear distortion. Nonlinear distortion has stimulated scattering and nonlinear refractive index of two. 1 Introduction Optical fiber The composition. Answer: the fiber consists of two basic […]
Reuters three times in a row on the CCTV news broadcast, Xinhua news agency, peoples daily, Guangming Daily and other media repeatedly reported, the era model Cui Genliang and his well recently become the focus of people attention and hot, especially the spirit of independent innovation won acclaim. There is a saying called monk chanting, […]

According to Reuters reports, NEC developed a new technology that can connect the information communication network between countries and regions of the sea optical cable The communication speed is increased by 2.5 times. 1 Optical fiber One can transport 34.9T bits of information, the equivalent of 540 million line capacity. It is reported that the […]
Because the monitoring cable transmission distance is very short, we recommend network The monitoring network is preferably not more than 90 meters, even the simulation of 75-5 monitoring is commonly used, we also recommend that no more than 500 meters, so the monitoring distance should be used Optical fiber The mode of transmission, then from […]
Distributed network Optical fiber Heat flow monitoring technology has been widely used in industrial field. Leakage monitoring system of optical fiber temperature measurement is expected to replace the traditional spot temperature sensor used in dam and dike, and can greatly improve the probability of finding the hydraulic structure and foundation of concentrated leakage passage. The […]
