QSFPP-40GLR4-X4-B Use Case
High-Density Data Center Interconnect Across Campus Buildings
In a multi-building enterprise campus, IT operations deployed four QSFPP-40GLR4-X4-B-Bundle modules to establish redundant 40GBASE-LR4 links over single-mode fiber spanning up to 10 km. This configuration supports high-bandwidth storage replication, live VM migrations and low-latency east-west traffic. Benefit: Achieves aggregated 160 Gbps throughput with hot-swap optics, minimizes link failures and scales seamlessly as the data center footprint grows.
Carrier Backhaul for Regional Telecom Network Expansion
A regional telecom provider leveraged the QSFPP-40GLR4-X4-B-Bundle (quantity four) to upgrade backhaul capacity between POPs. Each 40GBASE-LR4 channel transports voice, video and 5G mobile traffic over existing long-haul fiber corridors without costly OTN upgrades. Benefit: Delivers carrier-grade 40 Gbps links per lane, extends reach to 10 km, reduces capex by 30 % and accelerates time-to-market for new service rollouts.
High-Performance Computing Cluster Interconnect
A research lab integrated four QSFPP-40GLR4-X4-B-Bundle optics into its HPC fabric to link GPU-accelerated nodes across two buildings. The 40GBASE-LR4 modules ensure low-latency, lossless data flows for AI training workloads and simulation jobs. Benefit: Increases cluster bandwidth to 160 Gbps aggregate per QSFP port group, lowers jitter by 50 % and optimizes resource utilization for compute-intensive projects.
