A9K-2T20GE-E Use Case
High-Capacity Data Center Interconnect for Cloud Service Providers
A tier-1 cloud provider deploys the Cisco ASR 9000 with A9K-2T20GE-E line cards (2-port 10GE via XFP, 20-port GE via SFP) to build resilient metro and long-haul links between multiple data centers. By leveraging high-density 1 Gigabit Ethernet aggregation alongside 10 Gigabit Ethernet uplinks, the provider achieves 40% greater port density in a single slot, reduces fiber termination points, and cuts OPEX by 25%. The outcome is seamless east-west traffic scaling and sub-millisecond latency for mission-critical workloads.
Scalable Metro Ethernet Aggregation for Regional Service Providers
A regional telecom operator integrates A9K-2T20GE-E line cards into ASR 9000 POP routers to consolidate business customer access at the metro edge. The 20 extended GE ports connect customer CPE via SFP transceivers, while the 2 high-speed 10GE XFP uplinks aggregate traffic into the core network. This setup delivers on-demand bandwidth provisioning, 99.99% service availability, and simplified network operations. The result is accelerated time-to-revenue and SLA-driven QoS for enterprise Ethernet services.
Resilient Mobile Backhaul Infrastructure for Telecom Operators
A mobile operator builds an LTE backhaul ring using Cisco ASR 9000 chassis outfitted with A9K-2T20GE-E cards to interconnect cell sites and the core network. Each card’s 20 GE ports carry site-level traffic over SFP links, while the 2 XFP-based 10GE ports form a protected ring topology. This design ensures sub-50 ms failover, 30% lower power consumption per port, and seamless migration to 5G backhaul. The outcome is a future-proof, low-latency transport layer that meets stringent mobile SLA requirements.
