QSFP-100G-ER4L Use Case
Hyperscale Data Center Interconnect with 100GBASE-ER4-LITE
In large‐scale data centers requiring up to 40 km fiber spans, the QSFP-100G-ER4L-100GBASE-ER4-LITE QSFP28 pluggable module delivers reliable 100 Gbps links over single-mode fiber. By leveraging four 25 Gbps lanes and low-power optics, operations teams achieve seamless inter-pod connectivity, reduced latency, and sub-3.5 W power consumption—ensuring efficient scaling of compute clusters with minimal rack footprint and predictable network performance.
Metro Ethernet Service Provider Edge Aggregation
Service providers expanding 5G backhaul and business Ethernet offerings deploy the QSFP-100G-ER4L-100GBASE-ER4-LITE module at metro edge sites to aggregate customer traffic across distances up to 40 km. This pluggable QSFP28 solution simplifies network upgrades by fitting into standard 100G ports, delivering carrier-grade optical reach and resilience. The outcome is faster rollout of high-bandwidth services, reduced OPEX through uniform optics inventory, and enhanced SLA compliance.
High-Performance Computing Cluster Backbone Upgrade
Research facilities and financial trading firms accelerate data-intensive workloads by installing QSFP-100G-ER4L-100GBASE-ER4-LITE modules in their HPC switch fabric. The module’s extended-reach optics support multi-rack interconnects up to 40 km, enabling geographically distributed compute nodes to operate as a single cluster. Results include deterministic low-latency communication, optimized power efficiency, and simplified optical management for mission-critical simulations and real-time analytics.
