A9K-40GE-E Use Case
High-Density Metro Ethernet Aggregation for Service Providers
Telecom and cable operators deploy the Cisco ASR 9000 with the A9K-40GE-E 40-Port GE Extended Line Card (requires SFPs) at the metro edge to aggregate hundreds of 1 GbE customer circuits onto a resilient backbone. Leveraging 40×1 GbE ports, SFP-based optics and built-in MPLS, providers achieve pay-as-you-grow scalability, simplified optical reach planning and carrier-grade uptime. Outcome: Up to 80% reduction in port-churn CAPEX, sub-microsecond MPLS convergence and streamlined operations across multi-service networks.
5G Mobile Backhaul Convergence and Timing Synchronization
Mobile network operators integrate the A9K-40GE-E line card into ASR 9000 platforms to terminate and aggregate 5G RAN streams over 40×1 GbE interfaces using SFPs. With native IEEE 1588v2 and SyncE support, the solution delivers low-latency transport, precise timing and SLA assurance for voice, data and IoT services. Outcome: Guaranteed sub-50 µs latency, zero-packet loss during failover and tangible OPEX savings through consolidated backhaul infrastructure.
Scalable Enterprise Campus Core with Multi-Tenant Segmentation
Large enterprises leverage the Cisco ASR 9000 chassis with the A9K-40GE-E card to connect campus buildings, branch offices and data closets via 40×1 GbE SFP links. Integrated MPLS/VPN and advanced QoS enable secure multi-tenant segmentation, end-to-end traffic engineering and real-time voice/video prioritization. Outcome: Dramatic footprint reduction, simplified SFP inventory management and the ability to scale port density by 60% without forklift upgrades.
