Cisco Router NCS-55A1-48Q6H : 48x100G Ports , Segment Routing & High Density For Carrier Networks
The Cisco NCS-55A1-48Q6H is a high-performance aggregation services router designed for carrier-grade networks, data center interconnects (DCI), and large-scale enterprise WANs. Featuring 48x100G QSFP28 ports with flexible breakout options (4x25G or 4x10G), it delivers high-density, low-latency connectivity while supporting Segment Routing, EVPN/VXLAN, and MPLS for scalable traffic engineering.
✔ 48x100G Ports with Breakout Support – Each port can be split into 4x25G or 4x10G, optimizing bandwidth for diverse deployments.
✔ Carrier-Class Reliability – Redundant power supplies, hot-swappable fans, and In-Service Software Upgrades (ISSU) ensure 99.999% uptime.
✔ Silicon One ASIC Powered – Cisco’s advanced chipset enables line-rate forwarding with ultra-low power consumption.
✔ Modern Routing Protocols – Supports Segment Routing (SR-MPLS), EVPN/VXLAN, and IPv6 for future-proof networking.
✔ Telemetry & Automation – Built-in model-driven programmability (YANG/NetConf) for seamless integration with SDN/NFV environments.
