Driven by the explosive growth of generative AI, large model training and high performance computing clusters, traffic volumes within data centers continue to grow. computing networks demand higher bandwidth for high speed optical interconnects, pushing optical module technologies to evolve from 400G and 800G toward 1.6T and further to 3.2T.

At CIOE 2026, Accelink will host a live demo to demonstrate core 400G/lane technologies for high speed interconnects inside AI data centers. The demo will validate key capabilities for high speed pluggable optical module architectures and lay a technical foundation for the productization of next generation 3.2T optical modules.

400G/lane : A Critical Technical Milestone Toward 3.2T Optical Modules

As AI clusters keep scaling, data center networks face growing bandwidth requirements for high speed optical modules. Today’s mainstream 1.6T optical modules are mostly built on the 200G/lane architecture. For next generation 3.2T modules, raising the per lane data rate becomes a key industry priority.

Compared with conventional approaches that rely on increasing lane counts, 400G/lane technology delivers multiple benefits:
• Significantly higher port bandwidth density
• Reduced number of parallel optical lanes
• Lower system complexity
• Reduced overall power consumption

Multiple architectural options are being explored for 3.2T optical interconnects, including NPO, CPO and pluggable optical modules. Thanks to its mature ecosystem, flexible deployment and good system compatibility, pluggable optical modules remain a vital form factor for data center networks. Enabling 400G/lane is therefore regarded as a key milestone for 3.2T pluggable modules. Without increasing fiber core counts, optical link bandwidth can be directly doubled, substantially lowering system complexity and per bit transmission cost.

CIOE Live Demo: Demonstrating Critical Capabilities for Next Generation Interconnects

At CIOE 2026, Accelink’s live demo will exhibit real world link performance of 400G/lane technology for high speed interconnects in AI data centers, intuitively showcasing core capabilities of future high speed pluggable optical modules. The demo module integrates a high speed DSP built on advanced process nodes for high speed signal processing and link performance optimization, working together with a 400G/lane optical engine to form a complete product architecture.

Foundations for the 3.2T Era High Speed Optical Interconnect

Surging AI compute requirements are propelling data center networks into a higher bandwidth era. 400G/lane technology represents not only a major performance leap for optical modules but also a cornerstone for the 3.2T optical interconnect era. By continuously innovating high speed optical interconnect technologies and jointly exploring novel optoelectronic paths with industry partners, Accelink actively advances the ecosystem for next generation high speed optical interconnects.

Accelink warmly invites global customers and industry partners to visit our booth at CIOE 2026 and witness the new future of high speed optical interconnects empowered by 400G/lane technologies.
