801287-B21 Use Case
Inter-Building Data Center Backbone with 801287-B21-HP ASSY 10GB LR SFP+
In a multi-campus enterprise, network architects deploy the HP 801287-B21-HP ASSY 10GB LR SFP+ modules in core and distribution switches to establish single-mode fiber trunks up to 10 km between data halls. This solution delivers 10 Gbps full-duplex throughput, ultra-low latency and simplified cabling, enabling seamless east-west traffic, elimination of bottlenecks and future-proof scaling for virtualization and containerized workloads.
Metro Ethernet Service Delivery for 10 Gbps Customer Links
A regional service provider uses the 801287-B21 module in aggregation routers to provision 10 Gbps point-to-point Ethernet circuits over single-mode spans of up to 10 km. Leveraging long-reach LR SFP+ transceivers ensures carrier-grade reliability, strict SLA compliance and support for bandwidth-intensive applications like IP voice, video conferencing and cloud-on-ramp services, driving higher ARPU and customer retention.
High-Performance SAN Replication with HP 10 Gb LR SFP+
In a virtualized IT environment, storage administrators integrate 801287-B21-HP ASSY 10GB LR SFP+ modules into FCoE-capable switches to link primary and disaster-recovery storage arrays over 8–10 km single-mode fiber. This high-bandwidth, low-latency connection accelerates synchronous replication, optimizes RPO/RTO objectives and ensures uninterrupted data integrity for mission-critical databases and file services.
