Optical fiber technology develops rapid or branching development of super six types of network lines
In recent years, the development of science and technology to speed up the pace, over six cable manufacturers integrated wiring communication industry is also booming, erbium-doped fiber amplifier (EDFA), distributed fiber Raman amplifier (DRFA), semiconductor optical amplifier (SOA), optical time division multiplexing (OTDM) technology and dense wavelength division multiplexing (DWDM) technology a wide range of applications. Optical Fiber Communication technology is constantly developing in the direction of higher transmission rate and larger capacity.
How to protect fiber optic cable lines
The Internet users in our country are increasing gradually, and the one of Fiber Optic cable is getting bigger and bigger. In the protection of the line, our country has invested a lot of economy to maintain.
With the use of dense wavelength division multiplexing and high-speed digital communication technology, increasing information transactions have been concentrated on fewer nodes and lines, and higher and higher demand for optical network reliability has been put forward. According to statistics, every year China's optical cable has exceeded 2000 times to block, resulting in the loss of infinite direct communication beyond 1 billion yuan and serious loss to all sectors of the national economy. Therefore, network survival can become an important factor affecting network planning and construction, and maintenance and rehabilitation of optical path can seriously affect the survival of all networks. It has a very serious meaning to the construction of optical network.
