NCS2K-400G-XP – Cisco 400 Gbps XPonder Line Card

Introduction

The NCS2K-400G-XP is a high-density, two-slot DWDM line-card from the Cisco Network Convergence System 2000 series designed for service providers and large metro/core optical networks. It supports up to 400 Gbps of client traffic and 400 Gbps trunk capacity, enabling a single card to aggregate 10 GbE, 40 GbE and 100 GbE services into coherent DWDM wavelengths. Ideal for operators seeking tested telecom gear and refurbished networking equipment with future-ready capability.

Key Features & Benefits

• 🚀 High capacity – Supports up to 400 Gbps client traffic and 400 Gbps trunk per card.

• 🧩 Flexible client interface mix – Accepts 10 Gb, 40 Gb, and 100 Gb Ethernet (via QSFP+, QSFP28) for transport optimisation.

• 🌐 Advanced modulation schemes – Supports 100G via QPSK, 150G via 8-QAM and 200G via 16-QAM for DWDM trunk links.

• 🔌 Pluggable optics – Employs CFP2 trunk ports and QSFP/QSFP28 client ports for modular growth and reduced inventory.

• 🔧 Grooming and switching – Embedded OTN switching (ODU-2/ODU-4) for client-to-trunk mapping and service aggregation.

• ♻️ Upgradeable licensing – Pay-as-you-grow licensing model for client bandwidth and trunk functionality.

Ideal For

• 🏢 Telecom & service-provider core/metro optical networks aggregating 10/40/100 GbE services.

• 🏗 Data-centre interconnects requiring scalable 400 Gbps transport over fibre.

• 🔄 Network refresh projects migrating legacy 10G/40G services into high-density DWDM infrastructure.

• 🧰 Refurbished network equipment buyers seeking high capacity transport modules.

• 📶 Operators with existing Cisco NCS 2000 platforms (such as NCS2006, NCS2015) looking for modular growth.
