We want to introduce FiberMall’s roadmap for 800G, 1.6T, and 3.2T optical modules.<\/p>\n\n\n\n

The evolution trend of data center switching chips is as follows: a rapid growth of doubling every two years. 25.6T switching chips with 7nm process and 51.2T must choose 5nm process node. The 3nm process node is expected to be available in 2025 and support a 102.4T capacity for the switching chip.<\/p>\n\n\n\n

For the optical port, 25.6T optical modules with 64 400G optical modules<\/a>, which is already implemented in 2021. It is expected that next year with 64 800G modules, 8x100G solution to support the switch upgrade to 51.2T<\/p>\n\n\n\n

For 102.T switching capacity, 1.6T optical modules are required, and the optical port needs to reach 200G per wavelength rate, which is expected to enter the industrial node in 2025.<\/p>\n\n\n\n

Single-channel 100G is a large node that can support the landing of 400G and 800G optical modules, there is an opportunity to do 16x100G 1.6T solution, but FiberMall believes that 8x200G 1.6T is the industrial value.<\/p>\n\n\n\n

2. 800G optical modules are ready for deployment<\/p>\n\n\n\n

This is the first optical module that can be deployed before the system technology matures.<\/p>\n\n\n\n

3. Next-generation switching chips all support 800G optical module access<\/p>\n\n\n\n
