With the continuous emergence of cloud computing, big data, Internet of things, streaming media and other emerging technologies and services, the backbone network transmission rate will continue to upgrade from 100g to 200g / 400g. Operators put forward higher requirements for single fiber capacity. G. 654. E fiber will be the first choice for 200g, 400g and future Tbit / s ultra-high speed transmission technology.
With the promotion of new infrastructure, it is estimated that more than 550000 5g base stations will be built by the three operators in 2020. 5g construction will enter the golden construction cycle, and the optical network, an important part of the 5g industrial chain, is also constantly upgrading.
According to the prediction, in the next two to three years, the market share of super-100g network will exceed 60%, and 400g + will become the mainstream application of super-100g network.
The G.652 optical fiber used in the current network has been unable to meet the transmission needs of ultra-high speed, super large capacity and ultra long distance in the future optical transmission network.
For the next generation optical transmission network, lower fiber attenuation coefficient or larger effective area of optical fiber is more conducive to ultra-high speed, super large capacity and ultra long distance optical communication transmission. G. 654. E optical fiber has become the mainstream choice for operators to build 5g network because of its large effective area and low loss.
G. 654. E fiber can meet the two characteristics of ultra-low loss and large effective area at the same time, which is the best choice for 400g / 1t system. In addition to the two core advantages of ultra-low attenuation and large effective area, g.654. E optical fiber can also have excellent macro bending and micro bending performance under specific technology to meet the deployment needs of complex environment.
