QSFPP-40GBASE-SR4 Use Case
High-Density Data Center Spine-Leaf Aggregation with QSFPP-40GBASE-SR4-ONE
In a hyperscale data center environment, network architects deploy the QSFPP-40GBASE-SR4-ONE module on spine and leaf switches to aggregate sixteen 10 GbE links into four 40 GbE trunks over multimode OM3/OM4 fiber using a single QSFP+ port. This configuration maximizes port density, simplifies cabling with MPO/MTP connectors, and delivers up to 160 Gbps of bi-directional throughput per uplink bay, reducing power consumption by 40% and lowering per-Gb cost by 30% compared to discrete 10 GbE transceivers.
Low-Latency HPC Cluster Interconnect for Scientific Computing
A leading research university upgrades its high-performance computing (HPC) cluster interconnect with QSFPP-40GBASE-SR4-ONE modules to connect compute nodes and storage arrays across 100-meter multimode fiber links. The module’s four-lane parallel optics design achieves sub-2 µs port latency and 40 Gbps full-duplex bandwidth, boosting data ingestion and job throughput by 50%, enabling real-time analytics and large-scale simulation workloads with consistent low-latency performance.
Enterprise Campus Backbone Modernization with 40G Fiber
A multinational enterprise refreshes its campus network backbone by replacing legacy 10 GbE fiber uplinks with QSFPP-40GBASE-SR4-ONE QSFP+ transceivers on distribution switches, spanning multiple buildings over existing OM4 cabling. This upgrade quadruples backbone capacity, supports converged voice, video, and data traffic without rewiring, and delivers a 4× bandwidth increase per link while maintaining compatibility with existing MPO/MTP infrastructure—future-proofing the network for projected 5-year growth.
