Why Choose This Product?

• High port density in 2RU – 20 QSFP+/QSFP28 client ports and 8 DWDM trunks provide substantial optical capacity without requiring a large chassis footprint.
• Built for DCI – Cisco positions the NCS 1002 for data-center and data-center-interconnect applications, making it appropriate for high-capacity inter-site transport. 
• Multi-rate optical transport – Supports 100G, 200G, and 250G wavelengths, allowing capacity to be matched to network requirements.
• Mixed client speeds – 10GE, 40GE, and 100GE support allows existing and newer Ethernet infrastructure to share the same transport platform.
• Operational automation – IOS XR, YANG, NETCONF, RESTCONF, gRPC, telemetry, and ZTP provide a strong foundation for automated optical network operations. 
• Transport security – AES-256 MACsec provides encryption for supported client-side Ethernet traffic, addressing data-protection requirements for inter-site connectivity. 
• Serviceability-focused design – Redundant field-replaceable PSUs and fans, plus replaceable controller and SSD components, support maintenance without treating the chassis as a single disposable unit. 
• Capacity-per-rack optimization – Up to 2Tbps of client and trunk traffic in a 2RU chassis helps operators pursue higher optical density while controlling rack-space consumption.
