The correct answer isN402. TheN402 boardis specifically designed to support400G per wavelength transmission, making it ideal for high-capacity optical networks.
Key features of the N402 board include:
* High-Speed Transmission:Supports data rates up to 400G per wavelength, enabling efficient traffic aggregation in backbone and core networks.
* Advanced Modulation:Uses modulation schemes like DP-16QAM (Dual Polarization 16 Quadrature Amplitude Modulation) to achieve high spectral efficiency.
* Flexibility:Compatible with various network architectures, including OTN, WDM, and SDH.
* Scalability:Can be integrated into existing networks to boost capacity without requiring a complete overhaul.
Other options:
* N220:Typically supports lower data rates (e.g., 100G).
* N502:Designed for mid-range applications, not 400G.
* N602:Focuses on access networks rather than high-speed backbone transmission.

TheNCE-T (Network Cloud Engine - Transport)fully supportsvirtualization deployment. It can be deployed as a virtualized application on cloud platforms, leveraging technologies like VMware, OpenStack, or Kubernetes.
Key benefits of virtualization:
* Scalability:Virtualized deployment allows NCE-T to scale dynamically based on network demands.
* Flexibility:Enables integration with cloud-native environments and multi-vendor ecosystems.
* Cost Efficiency:Reduces hardware dependency by running on shared infrastructure.
The statement that NCE-T does not support virtualization is therefore incorrect.
