The 400G optical module uses PAM4 technology to achieve 400Gbps transmission, increasing energy efficiency by 20% and reducing fiber usage by 75%. The market is expected to grow by over 80% by 2025, leading the next generation of high-speed interconnection.
With the rapid development of cloud computing, artificial intelligence, and 5G networks, the demand for bandwidth in data centers is growing exponentially. The 400G optical module, with its outstanding performance, is gradually becoming the core component of the next generation of high-speed networks. So, what are the advantages of 400G optical modules?
1, Ultra high bandwidth density
The 400G optical module adopts PAM4 (4-stage pulse amplitude modulation) technology and achieves a transmission rate of 400Gbps within a single module through a channel architecture of 4 × 100Gbps or 8 × 50Gbps. Compared to traditional NRZ modulation, PAM4 doubles the bit rate per channel and achieves higher bandwidth density within a compact package. One 400G port can also be split into four independent 100G channels, increasing switch port utilization by up to 300% and significantly improving data center space efficiency.
2, Excellent energy efficiency performance
In terms of energy efficiency, the 400G optical module also performs outstandingly. Taking 400G QSFP112 FR4 as an example, its power consumption has been reduced to below 10W. Some products that adopt innovative architectures have higher energy efficiency, and overall power consumption can be reduced by 20% compared to similar solutions. Low power consumption not only reduces the PUE of data centers, but also strongly supports the construction of green data centers.
3, Save fiber optic resources and deploy at low cost
The 400G optical module carries 100G data through a single wavelength, significantly improving spectral efficiency and reducing fiber resource consumption. Compared to traditional solutions, fiber optic usage can be reduced by 75%, equipment procurement costs can be lowered by up to 40%, and overall ownership costs can also be significantly reduced.
4, Wide market prospects
At the market level, 400G optical modules are experiencing explosive growth. According to Cignal AI statistics, the shipment of high-speed (400G and above) optical modules will exceed 42 million units by 2025, an increase of over 80% compared to 2024. By 2025, the revenue of the Shutong optical module market will exceed 18 billion US dollars, with outstanding contributions from categories of 400G and above. It is expected that by 2029, the size of this niche market will approach $30 billion.
In summary, the 400G optical module, with its high bandwidth density, excellent energy efficiency, cost savings, and broad market prospects, is leading the optical communication network towards the next generation of high-speed interconnection.
