With the breakthrough development of information demands such as the integration of three networks, new IPTV services and big data processing, the demand for communication network bandwidth has shown an explosive growth trend, with the average annual growth rate of backbone network transmission bandwidth reaching more than 50%.
As the three major operators successively launched 100G centralized procurement in 2013, the backbone network has fully entered the 100G era.
In order to adapt to the rapid increase in network traffic, it is expected that the 400G era will usher in by 2017.
As the infrastructure of optical fiber network construction, optical fiber has a service life of more than 20 years. It is difficult to change after the laying construction is in place. Therefore, when choosing optical fiber, you need to consider all network needs during its life span, so it has ultra-low loss. Optical fiber has been favored by the market.
