Next-Generation Data Center Interconnect

Next-Generation Data Center Interconnect

Near-packaged Optics (NPO) is an innovative optical interconnect technology that sits between traditional pluggable optical modules and Co-Packaged Optics (CPO). By placing the optical engine in very close proximity to the switch chip, NPO achieves shorter optoelectronic signal transmission paths while maintaining the advantages of serviceability and upgradability.

Compared to CPO, NPO is easier to implement technologically and has a clearer path to commercialization, while significantly reducing power consumption and increasing bandwidth density. Sunyu Photonics provides professional wafer-level and chip-level testing solutions for NPO, helping customers achieve efficient and reliable testing during product development and mass production. Our system is optimized for the high-density optoelectronic integration characteristics of NPO devices, supporting multi-channel parallel testing while balancing optical coupling precision with test throughput.

Frequently Asked Questions

Common questions about NPO testing

Which is better for my product, NPO or CPO?

NPO as a transitional solution has relatively lower packaging complexity and technical difficulty, making it easier to implement; CPO represents a longer-term technology direction. We provide professional recommendations based on your product positioning and application scenarios.

What wafer sizes does your system support?

Our system supports 4-inch, 6-inch, 8-inch, and 12-inch (300mm) wafers, meeting various requirements from R&D to mass production.

How is NPO testing different from traditional pluggable module testing?

NPO devices have higher channel density and stronger optoelectronic integration, requiring more precise alignment systems and higher-efficiency parallel testing capabilities. Our system is specifically optimized for these characteristics.
