A global cloud service provider deploys the Q9G82A-Aruba 40G QSFP+ LC ER4 40km SMF XCVR to link two data centers separated by 30 km of single-mode fiber. Leveraging ER4 optics for 40 km reach, the solution delivers full-duplex 40 Gbps connectivity that supports live VM migrations, synchronized database replication and multi-site disaster recovery. Benefit: Scalable, low-latency intersite bandwidth that boosts cross-site application performance and reduces TCO by minimizing the number of required link upgrades.
A regional telecom carrier builds a resilient metro Ethernet ring by installing Q9G82A-Aruba 40G QSFP+ LC ER4 40km SMF XCVR modules in its aggregation switches. Covering spans up to 40 km, the ER4 optics enable 40 Gbps high-capacity links between PoPs (Points of Presence), carrying wholesale Ethernet and business VPN services. Benefit: Enhanced network uptime with optical reach optimized for long-haul spans, simplified inventory management with a single transceiver type, and accelerated service provisioning for enterprise subscribers.
A leading financial exchange integrates the Q9G82A-Aruba 40G QSFP+ LC ER4 40km SMF XCVR into its trading floor switch fabric to connect matching engines and risk-management clusters located in separate facilities 20 km apart. The ER4-grade optics ensure deterministic latency and error-free 40 Gbps links that uphold stringent regulatory SLAs. Benefit: Ultra-low and consistent network latency for high-frequency trading, simplified optical planning with fixed 40 km reach, and guaranteed throughput to support real-time market data feeds.
