5G construction is a big opportunity for the optical communication industry, which is conducive to the development of the industry, and the current development trend is also very good. At present for the 5G development in the optical network layer laid, have done almost. Light module company has made a good contribution to 5G foundation. From the perspective of network carrying capacity, all solutions have corresponding products whether it is the carrying capacity of the network technology in front, middle and back, such as the long distance optical module, o-band, c-band and the low number of optical fibers.
The arrival of 5G brings infinite opportunities, and the demand for the whole bandwidth business increases. However, only optical fiber communication can explore the infinite potential of the bandwidth. Optical fiber is the core step of the whole communication foundation and the core of the national communication development.
5G undoubtedly brings great opportunities to the supply chain of optical devices and optical modules. Brand - new network construction, from the light module manufacturers point of view, is not a trend toward convergence. Operators and equipment vendors understand some of the technology, bring different product requirements. From the light module manufacturer's point of view, 5G application scenarios have new requirements for modules.
In the past, the rapid development of 40G to 100G is now in the indirect period of 100G to 400G. From the data point of view, the demand for 400G optical module or even 800G optical module in the future is very certain.
What is the cost comparison between coherent module and LR type module such as 100G/200G?
Coherent 100G is different application scenarios, and LR transmission distance of 10 kilometers, mainly used in the data center, between coherent module is applied in the backbone has hundreds of kilometers, 100G both there is no overlap, with subsequent 800G and the higher rate, and sinking coherence technology to man, they will have some competition, including 400G will be various distance scene will be applied. In the 100G stage, the cost difference between coherence and LR is very big, and the backbone and man will use coherent modules.
