Power optical fiber communication system

Power system communications network in China dedicated communications network in a larger scale, to develop a more complete private network. With the trend of fiber optic communications network acceleration of China's power in many parts of the private communication network has been basically completed from the main trunk to the access network to the optical transition process. Currently, optical fiber communications power systems business are carrying voice, data, broadband, IP and other conventional telecommunication services; electricity production professional business to protect, automatic safety devices and broadband required for the electricity market data. In particular the protection and automatic safety device on cable reliability and security put forward higher requirements. It can be said optical fiber communication has become a safe and stable operation of power systems and power system production and daily life in an important and indispensable part. Optical fiber communication applications in the power of communication initially followed traditional buried telecommunications sector, pipelines, overhead and other methods common laying fiber optic cable, optical fiber communication systems constitute power. As we all know, the power system is composed of energy production, transmission, distribution and consumption form a whole. To achieve cross-regional, long-distance electricity transmission, power system built around the high-voltage transmission lines throughout; urban and rural areas to meet the demand for electricity production and life of the general public, there are criss-cross, clouds the streets of the village road and the channel transmission and distribution poles . It can be said, high, medium and low voltage power distribution lines is the most extensive coverage of network infrastructure, and it is the basis of strong, compared to other networks such as telecommunications, radio and television networks have a higher reliability. Therefore, how to take full advantage of this unique network of power system resources, has long been an important subject of painstaking research. 

As technology advances to the last century of the seventies and eighties, which are different from traditional cable attached to power lines hanging on power tower on the processing of optical composite cable was developed, which are collectively referred to as the power cable special cable . Power systems and other optical fiber communication optical fiber communication system is one of the biggest differences between the particular nature of communication cable. External damage to the power of special optical potential by a small, high reliability, although the relatively high cost of its own, but the construction of the building costs are lower. After years of development, the special power cable manufacturing and engineering design has matured, especially in OPGW and ADSS technology, special optical power in the country has begun a large-scale applications, such as the Three Gorges Project in the long-distance trunk lines, OPGW cable. Relying on the power system of special fiber optic line their own resources, to avoid the frequency resources, routing coordination, electromagnetic compatibility and other aspects of the contradictions and disputes with the outside world, there is a great initiative and flexibility.
