FS, a leading provider of ICT products and solutions, has introduced its latest 1.6T OSFP IHS (Closed Finned Top) optical transceivers, including the OSFP-DR8-1.6T and OSFP-2FR4-1.6T models, specifically designed for high-density AI and HPC InfiniBand XDR networks. These advanced modules deliver full 1.6T throughput in next-generation NVIDIA GB300/B300 architectures, offering organizations a transformative solution to harness AI’s full potential while maintaining efficiency and compatibility. By overcoming traditional performance bottlenecks, FS empowers enterprises worldwide to scale their infrastructure for the most complex computational challenges.
As AI infrastructures evolve from rack-scale to row-scale deployments, enterprises face increasing link distances, high east-west traffic, and tighter power constraints. Traditional copper interconnects are now reaching their physical limits in both reach and signal integrity. At the same time, NVIDIA’s GB300/B300 platforms demand high-performance 1.6T optical interconnects. Consequently, pluggable 1.6T optical solutions have emerged as a critical component for AI and HPC network upgrades, enabling a smooth transition beyond 800G while meeting both performance and energy targets of large-scale AI clusters.

The FS 1.6T OSFP IHS series balances high bandwidth with energy efficiency, supporting the growing needs of next-generation AI fabrics. The OSFP-DR8-1.6T module provides up to 500 meters of connectivity, ideal for switch-to-switch and switch-to-server interconnections in AI data centers. Meanwhile, the OSFP-2FR4-1.6T supports up to 2 kilometers, offering longer links for large AI clusters and trillion-parameter AI models. Both modules feature integrated heat sinks with cooling fins, ensuring compatibility with air- and liquid-cooled environments for flexible deployment.
“The evolution from 800G to 1.6T is not only about higher speed but also about reshaping the optical interconnect architecture for AI,” said Kyrie Zhang, Senior Product Manager at FS Inc. “FS is committed to delivering proven and ready-to-deploy 1.6T solutions, and our 1.6T OSFP IHS transceiver series gives global professional organizations the reliability and efficiency needed to overcome performance bottlenecks and scale massive clusters.”

Rigorous testing on NVIDIA Quantum-X800 switches ensures low BER, high signal integrity, and durability, reducing long-term operational risks. Leveraging 8x 200G PAM4 modulation and Broadcom 3nm DSP technology, the modules provide higher bandwidth density while consuming as little as 25–26W. With Silicon Photonics (SiPh) technology in OSFP-DR8-1.6T, thermal loads and cooling requirements are minimized, allowing data centers to scale AI workloads efficiently.
In summary, FS’s 1.6T OSFP IHS transceivers combine high bandwidth, low power consumption, and robust thermal performance, making them ideal for powering today’s rack-scale and row-scale AI clusters. Verified on NVIDIA Quantum X800 platforms and compliant with InfiniBand XDR standards, this portfolio positions FS to lead the next wave of high-density AI and HPC network deployments.
