JH409A Use Case
Hyperscale Data Center Backbone with JH409A-5940 2P QSFP+ & 2P QSFP28
In a large‐scale cloud provider environment, network architects deploy the JH409A-5940 2P QSFP+ AND 2P QSFP28 MOD PLNT in top‐of‐rack switches to aggregate dual 40 Gbps and dual 100 Gbps uplinks. This high‐density module eliminates port exhaustion, simplifies cable management and drives 4× more throughput per slot. Benefit: Achieve scalable 10/40/100 GbE connectivity with 50% lower rack-space footprint and predictable performance at hyperscale.
Low-Latency HPC Cluster Interconnect Using JH409A-5940 Modular Plant
A university research lab integrates the JH409A-5940 2P QSFP+ AND 2P QSFP28 MOD PLNT into its HPC cluster switches to deliver dual 40 Gbps lanes for MPI traffic and dual 100 Gbps for parallel data transfers. The result is sub-microsecond latency and sustained throughput for large-scale simulations and AI workloads. Benefit: Reduce compute-to-compute round-trip delay by up to 30% while supporting future 100 Gbps-per-node expansion without additional chassis upgrades.
Enterprise Core Network Convergence with Dual-Speed QSFP Module
A global enterprise replaces legacy 10 GbE interfaces at its core with the JH409A-5940 2P QSFP+ AND 2P QSFP28 MOD PLNT, enabling simultaneous 40 Gbps SAN traffic and 100 Gbps campus uplinks on a single slot. IT gains seamless VLAN segmentation, unified LAN/SAN fabrics and hot-swappable optics. Benefit: Consolidate network layers, cut power consumption by 25%, and accelerate cross-datacenter replication with resilient, high-performance connectivity.
