High-Speed 40GE Expansion for Cisco ASR 1000 Series Aggregation Routers
Cisco EPA-1X40GE 1-Port 40-Gigabit Ethernet Port Adapter
The Cisco EPA-1X40GE is a high-performance 40-Gigabit Ethernet Port Adapter designed for Cisco ASR 1000 Series routers. With one QSFP+ interface, it delivers line-rate 40 Gbps throughput for high-bandwidth aggregation, service provider edge, enterprise WAN, and data center deployments. Supporting IEEE 802.3ba compliance, this adapter enables breakout into 4x10GE for flexible connectivity, while being compatible with a wide range of QSFP+ optics including SR4, LR4, and ER4.
Engineered for carrier-grade reliability, the Cisco EPA-1X40GE provides advanced MPLS, L2VPN, L3VPN, QoS, NetFlow, and MACsec encryption capabilities, ensuring secure and efficient traffic management. Its hot-swappable EPA form factor allows tool-less installation and field replacement, minimizing downtime in critical environments.
With low power consumption (~20W), robust Cisco IOS XE support, and integration with modern telemetry and automation tools, the Cisco EPA-1X40GE is the ideal solution for organizations seeking scalable 40GE connectivity, enhanced performance, and secure service delivery.
