1.6T-DR8 500m OSFP-RHS Transceiver is a high-speed optical module designed for next-generation AI data centers. Its core feature is delivering up to 1.6 Tbps total bandwidth through eight independent channels (DR8 architecture) over single-mode fiber with a reach of up to 500 meters. It adopts the OSFP form factor, which is specifically designed for high density and high performance. The module is primarily used to connect AI server clusters with high-speed switches, addressing bandwidth bottlenecks in massive data exchange within data centers.

Application Areas
●AI Data Centers and Intelligent Computing Centers
Connects AI server clusters (such as GPU/TPU clusters) to high-speed switches, enabling low-latency, high-speed exchange of massive training data. It serves as the "blood vessel" for AI clusters with tens of thousands of accelerators.
●High-Performance Computing (HPC) Clusters
Meets the demands for massive data synchronization between compute nodes in supercomputing centers, preventing the network from becoming a performance bottleneck.
●Hyperscale Data Center Backbone Networks
Used for core interconnections in leaf-spine network architectures within data centers, improving overall network bandwidth and scalability.
●Data Center Interconnects
Specifically designed for high-speed, stable connections between racks over distances of up to 500 meters.
As large model parameters surge and training cluster sizes continue to expand, communication efficiency between GPUs/TPUs directly determines overall computing power. The 1.6T module minimizes the waiting time for parameter synchronization. Its DR8 architecture and 500‑meter transmission capability make it particularly suitable for large-scale, distributed AI server clusters.
The design of the 1.6T-DR8 500m OSFP-RHS Transceiver is compatible with upcoming 102.4 T switches and next‑generation AI computing platforms such as the NVIDIA GB300, preparing infrastructure upgrades for the next 2–3 years.
For existing data centers, the 1.6T-DR8 500m OSFP-RHS Transceiver provides double the bandwidth of current mainstream 800G solutions. It can multiply interconnection capacity between racks without significantly increasing cabling or management complexity.
The 1.6T-DR8 500m OSFP-RHS Transceiver is a dedicated network component designed for future ultra‑high computing demands. Its applications are highly concentrated in the most technologically advanced and data‑throughput‑intensive fields, including AI training, hyperscale cloud computing, and high‑performance computing.
