With the mature development of 100G technology and the advent of 100G products, the deployment of large enterprise network and data center is evolving towards 100G. At present, 100G optical modules on the market include CFP, CFP2, CFP4, QSFP28 and CPAK. The sizes of 100G optical modules in different packages are different. Among them, the 100G optical module in QSFP28 package has the smallest size and the lowest power consumption, making it an ideal choice for data centers and enterprises.

With the development of 100G technology, the market competition of 100G optical module is becoming more and more fierce. Many optical module manufacturers, such as ETU-LINK, begin to invest in product production and development to promote the utilization rate of 100G optical module. In addition, the extensive use of 25G technology in the connection between server and tor switch also intensifies the upgrade from 25G network to 100G network. In most large-scale data centers, 10G servers and 40G switches are gradually eliminated, replaced by 25G servers and 100G switches, which makes the shipment of 100G switches and modules exceed that of 40G devices.

With the investment and construction of 100G network, the application of 100G optical module continues to grow, and has become the most widely used and fastest Ethernet connection. Contrary to the massive growth of 100G business, the demand of 40G and 10G has declined. In the future, low-cost 40G applications will be considered only when 100G services cannot be deployed due to technical or compatibility problems. That is to say, when the 100G optical module overcomes the supply bottleneck, the market demand for it will continue to grow, and the price gap between 100G and 40G modules will further narrow.

At present, 100G QSFP28 optical module is the main optical module in the digital communication market. By 2022, 100G QSFP28 optical module will still occupy the mainstream. Because the transmission distance of 100G QSFP28 PSM4 and 100G QSFP28 CWDM4 optical module are 2km, but the total application cost of 100G QSFP28 cwdm4 optical module is relatively low, and the demand will rise to a certain extent in the future. On the contrary, the demand of 100G QSFP28 PSM4 will decline. The demand for 100G QSFP28 SR4 will be relatively stable and will not fluctuate greatly.

The capacity of 100G optical module will be gradually improved in the future, so the average price of 100G optical module will be relatively lower. In 100G data communication products, cwdm4 may become the mainstream product, and its price decline will narrow. In terms of price, the overall price of 100G digital optical module will continue to decrease to a certain extent, and it is expected that the price will decrease by 14% in 2020.

With the growth of information technology (it) data, the network is developing towards higher speed and larger capacity. At the same time, it puts forward higher requirements for network technology. In the next few years, 100G bandwidth is far from enough for super large-scale or cloud data centers, so 200G / 400G will become the mainstream of the next generation of data centers.
