A9K-8T/4-E Use Case
Metro Ethernet Aggregation for Tier-1 Service Providers
In a nationwide ISP network, the A9K-8T/4-E 8-Port 10GE DX Extended Line Card (requires XFPs) aggregates customer circuits at the central office, delivering bi-directional 10 Gbps links over single-mode fiber up to 80 km. By consolidating multiple 1 Gbps feeds onto eight 10 Gbps DX ports, operators achieve 8× density gains and 60% lower rack space usage. Outcome: streamlined CAPEX through fiber reuse, 50% reduction in cross-connect complexity, and guaranteed SLA compliance with sub-millisecond fail-over.
High-Capacity Data Center Interconnect (DCI) for Enterprise Clouds
A global enterprise uses the A9K-8T/4-E line card with XFPs to interconnect multi-rack data halls across two data centers. Each of the eight 10GE DX links runs extended reach to 40 km, enabling active-active workload balancing and disaster recovery. Benefit: 8× scalable 10 Gbps lanes deliver 80 Gbps total bandwidth, cutting inter-site latency by 30% and boosting application performance, while centralized management reduces operational overhead by 40%.
5G Mobile Backhaul Edge for Carrier Networks
At the mobile edge aggregation site, telecom carriers deploy the Cisco ASR 9000 line card A9K-8T/4-E with XFP optics to terminate 5G macro cell backhaul. Eight independent 10 Gbps DX links provide high-density connectivity for up to 16 small cells via DWDM Mux, reaching 60 km. Outcome: a 75% increase in per-site capacity, seamless bandwidth scaling for future 5G-Advanced services, and enhanced network resiliency with hardware-based hitless protection.
