Silicon photonics has emerged as the mainstream technology for high-speed optical modules, offering the advantages of lower power consumption and reduced costs. Silicon photonics technology integrates optical components onto silicon wafers using conventional semiconductor manufacturing processes, significantly reducing cost and power consumption. Huawei has released the world‘s first single-wavelength 1.6Tbps silicon photonics module, achieving 70% volume reduction and 40% power reduction using third-generation silicon photonics integration technology.

Silicon photonics currently accounts for 50–70% of the 800G/1.6T market, with InnoLight’s 800G silicon photonics modules achieving approximately 50% market share. The company‘s self-developed silicon photonics chips have reached 95% yield, reducing costs by 30% compared with traditional approaches. By 2030, the market share of optical transceivers incorporating integrated silicon photonic modulators is expected to grow from 43% in 2025 to 76%.

4.2 Linear Direct Optics (LPO)

Linear Direct Optics technology removes the DSP chip from the optical module, achieving dual optimization of power consumption and performance. Eoptolink’s 800G LPO modules achieve a 50% reduction in power consumption and have secured orders from major customers including Meta and Amazon, making them well-suited for AI data center requirements. LPO module revenue is expected to account for approximately 15% of the optical module market, becoming a significant growth segment.

4.3 Co-Packaged Optics (CPO)

Co-Packaged Optics represents the next frontier in optical interconnect technology. CPO integrates the optical engine directly with the switching ASIC in a single package, reducing the electrical signal transmission path from 15–30 centimeters to less than 1 centimeter, thereby reducing 800G optical module power consumption by over 85%.

The CPO market is expected to become a rapidly growing segment, with market value contributions projected to exceed $9 billion by 2030. However, large-scale CPO deployment is not expected until after 2027, as challenges remain in fiber-to-photonic IC alignment accuracy, thermal management, and reliability design.

Supply chain constraints affecting upstream components, including electro-absorption modulated lasers (EML) and continuous-wave (CW) lasers, continue to impact delivery schedules. The ongoing technology transition from pluggable modules to near-packaged optics (NPO) and co-packaged optics (CPO) introduces uncertainty regarding actual shipment performance. Additionally, the technology conversion pace will significantly influence manufacturers’ actual shipment volumes.

As TrendForce concludes, data traffic between racks and across clusters will continue to rise as compute density scales. Consequently, advances in—and supply of—high-speed optical modules, lasers, and other optical components will become a decisive factor, alongside GPUs and memory, in determining the pace and cost of future compute expansion.
