QSFP-100GBASE-SR4 Use Case
High-Density Spine-Leaf Data Center Fabric
Scenario: A large enterprise deploys a spine-leaf Ethernet fabric using OM4 multimode fiber to interconnect top-of-rack (ToR) and spine switches. The QSFP-100GBASE-SR4 QSFP28 pluggable module delivers 100 Gbps per port over four 25 Gbps lanes, consolidating cabling and switch interfaces. Outcome: Achieves 4× higher bandwidth density, reduces fiber count by 75%, and lowers power and port-count costs while maintaining sub-2 µs latency.
Ultra-Low-Latency High-Frequency Trading Network
Scenario: A financial trading firm requires deterministic, low-latency Ethernet links between matching engines and market gateways in its colocation facility. The QSFP-100GBASE-SR4 QSFP28 module provides a 100 GbE short-reach connection with optimized signal integrity on OM3/OM4 fiber. Outcome: Enables sub-500 ns round-trip latency, ensures millisecond-level trade execution, and delivers competitive advantages in price discovery and order routing.
Scalable Hyperscale Cloud Aggregation
Scenario: A hyperscale cloud operator aggregates racks of GPU/CPU servers for AI/ML workloads across multi-pod data halls. Deploying QSFP-100GBASE-SR4 QSFP28 modules on aggregation switches ensures 100 Gbps Ethernet connectivity over OM4 fiber between pods. Outcome: Supports linear scaling of AI training clusters, accelerates data transfer by 50%, and simplifies network expansion with a future-proof 100 GbE short-reach backbone.
