With the explosive growth of AI large language model training, high-performance computing (HPC), and cloud computing services, the demand for high-speed optical interconnects in data centers is accelerating at an unprecedented pace. JH Optoelectronic delivers a comprehensive portfolio ranging from 100G to 1.6T high-speed optical transceivers, active optical cables (AOC), and passive direct attach copper cables (DAC), building a high-bandwidth, low-latency, and highly reliable interconnect foundation for Spine-Leaf architecture data centers and HPC supercomputing centers.
▲ Data Center Spine-Leaf Architecture and HPC Supercomputing Center High-Speed Interconnect Topology
Employing a two-tier CLOS fabric, the Spine layer handles high-speed forwarding while Leaf switches connect server and storage nodes. Compared to traditional three-tier architecture, east-west traffic forwarding efficiency is improved by more than 3x with 50% lower latency, making it ideally suited for cloud-native and distributed computing environments.
HPC supercomputing centers leverage InfiniBand or RoCE (RDMA over Converged Ethernet) high-speed interconnect protocols, demanding ultra-low latency and exceptional data integrity from optical transceivers. JH's 800G OSFP/QSFP-DD series is purpose-optimized for HPC workloads, delivering 100 Gbps per lane across 8 parallel channels.
High-speed interconnection among GPU clusters, 800G OSFP/QSFP-DD delivering ultra-low latency communication to support thousand-GPU parallel training and accelerate model convergence.
Under Spine-Leaf architecture, 400G/800G optical transceivers enable high-bandwidth connectivity from server to Leaf and Leaf to Spine, supporting deployment at million-server scale.
InfiniBand NDR/NDR200 networks with 800G to 1.6T optical transceivers provide massive bandwidth for compute-intensive workloads such as weather simulation, genomics, and computational fluid dynamics.
Coherent optical transceivers enable inter-data center connectivity spanning hundreds of kilometers. 400G ZR/ZR+ solutions cover metro to long-haul transmission, establishing active-active data center architectures.
NVMe-oF (NVMe over Fabrics) storage networks demand extremely low latency and high bandwidth. 100G/200G optical transceivers provide efficient interconnect for all-flash storage arrays.
In high-frequency trading (HFT) and real-time risk control scenarios where nanosecond-level latency is critical, DAC/AOC short-reach solutions ensure minimal transmission delay.
