BizLink has started shipping small volumes of co-packaged optics, marking an important step forward for high-speed data center connectivity and next-generation AI infrastructure. However, the company says the path to large-scale adoption is still facing several technical hurdles.
Chairman Roger Liang noted that the biggest challenges are not tied to production capacity. Instead, the key obstacles involve fiber array unit assembly, thermal management, and long-term system reliability. These areas are critical because co-packaged optics place optical components much closer to high-performance processors and networking chips, creating new demands for precision, heat control, and durability.
Co-packaged optics, often called CPO, are seen as a major breakthrough for data centers handling massive AI workloads, cloud computing, and high-bandwidth networking. By integrating optical connections closer to the chip, CPO can help reduce power consumption, improve signal performance, and support faster data transmission compared with traditional pluggable optical modules.
BizLink’s early shipments suggest that the technology is moving from research and validation into real-world use. Even so, scaling CPO for broad commercial deployment will require improvements across the supply chain and system design. FAU assembly is especially important because it requires extremely accurate alignment of optical fibers, where even tiny deviations can affect performance.
Thermal management is another major issue. As networking equipment becomes more powerful, heat becomes harder to control. Since CPO brings optical and electronic components closer together, manufacturers must ensure that performance remains stable under demanding operating conditions.
System reliability also remains a central concern for customers. Data centers need hardware that can operate continuously with minimal downtime. Before CPO can be widely adopted, suppliers must prove that these solutions can meet strict reliability standards over long periods.
Although mass deployment may still take time, BizLink’s progress shows growing momentum behind co-packaged optics. As artificial intelligence, cloud services, and high-speed networking continue to expand, demand for more efficient optical interconnect technology is expected to rise. If the remaining engineering challenges can be solved, CPO could become a key technology for the next generation of data center infrastructure.
