Product Highlights
- High-Density 400G Scaling & Form Factor: Packs massive 400Gbps line-rate performance into a standard, compact QSFP-DD footprint. It maximizes faceplate port density on next-generation routing platforms and seamlessly integrates into modern high-density slots with optimized thermal dissipation.
- Native IPoDWDM Network Architecture: Simplifies network layers by plugging directly into core routing platforms (such as Cisco 8000 and ASR 9000 Series). This eliminates the need for bulky, standalone optical transponder shelves, saving valuable rack space and reducing CapEx/OpEx.
- Flexible Multi-Rate & Modulation: Offers deployment flexibility by supporting multiple operational modes (100G, 200G, 300G, and 400G). It leverages advanced DP-QPSK, DP-8QAM, and DP-16QAM modulation formats to optimize capacity and spectral efficiency based on link characteristics.
- Standard 80km Reach via oFEC: Utilizes advanced Open Forward Error Correction (oFEC) to significantly improve signal quality and optimize the link budget, ensuring reliable, error-free 400Gbps transmission up to 80 km over standard single-mode fiber (SMF).
- Metro Aggregation & DCI Optimization: Perfectly positioned and optimized for high-capacity metro aggregation, enterprise data center interconnects (DCI), and regional transport links without requiring heavy optical transport infrastructure.
- C-Band Tunability: Supports software-defined grid wavelength tuning across the entire ITU-T C-band spectrum. Fully compatible with standard fixed-grid and advanced flex-grid network architectures, optimizing inventory management and link provisioning.
- Real-Time Coherent Telemetry: Features built-in optical performance monitoring (OPM) capabilities. Provides network operators with real-time telemetry data under Cisco IOS XR, including Chromatic Dispersion (CD) and PMD for proactive link maintenance.
- OpenZR+ MSA Standards Interoperability: Fully compliant with OpenZR+ Multi-Source Agreement (MSA) specifications, ensuring robust line-side interoperability in open, multi-vendor optical environments.
