2020 is also a year for Chinese cloud vendors to leap forward. Affected by the epidemic, the demand for bandwidth in online applications has driven the overall demand of Chinese cloud vendors in 2020. From the demand side, developed markets such as the United States have already entered the cloud computing 2.0 era, while my country's cloud computing has entered a 1.0 to 2.0 transition period, and traditional enterprises have a relatively low proportion of cloud computing. The main logic for China's cloud computing to achieve high growth in the future is to increase the cloud access rate of traditional enterprises and the continuous deepening of cloud access. In 2020, Chinese cloud manufacturers generally adopt 25G AOC/DAC+100G CWDM4 optical transceivers, and overall demand has increased by 23%.
JD Cloud released the new generation of its self-developed server on Mar 2, which will be officially put into use in April. As the important cloud based infrastructure for the industry, JD aims to continuously upgrade the product to support and drive business development.
Here is JD Cloud data centers transceivers roadmap and deployment of 400G/200G transceivers modules:
