QSFP-40G-BIDI-SR-MM850 Use Case
Spine-Leaf Data Center Interconnect with 40G BIDI Optical Transceiver
In hyperscale data centers deploying leaf-spine architectures, the QSFP-40G-BIDI-SR-MM850-QSFP+ 40G BIDI Optical Transceiver (850nm, 100m, SR) delivers bi-directional 40Gbps links over a single multimode fiber. This reduces cabling complexity by 50%, maximizes existing OM3/OM4 infrastructure and accelerates deployment with plug-and-play simplicity.
Campus Building-to-Building Backbone over Multimode Fiber
Universities and corporate campuses can link adjacent buildings up to 100 m apart using the QSFP-40G-BIDI-SR-MM850-QSFP+ 40G BIDI Optical Transceiver (850nm, 100m, SR). By halving the fiber count, organizations cut CAPEX and streamline maintenance while delivering 40G high-definition video streaming, centralized storage access and resilient Ethernet services.
High-Performance Computing Cluster Node Connectivity
For AI and HPC clusters requiring low-latency 40G interconnects within server rows, the QSFP-40G-BIDI-SR-MM850-QSFP+ 40G BIDI Optical Transceiver (850nm, 100m, SR) provides reliable, short-reach links on existing multimode cable. This enhances node-to-switch throughput, optimizes GPU utilization and supports data-intensive workloads with sub-microsecond latency.
