Inventory Enterprise-Grade Optical Router 400G

Enterprise-grade 400G optical routers provide high-throughput, scalable, and secure networking solutions for data centers, telecom, and AI-driven networks.Key Products and Bundles

Cisco QDD400GZR-15-BUN is a routed optical networking bundle designed for high-performance environments, offering 15x400G ZR ports. It is optimized for data centers and telecom providers requiring high bandwidth and scalability, with advanced features for monitoring, diagnostics, and firmware management . Cisco 400G QSFP-DD High-Power (Bright) Optical Module supports Ethernet and OTN clients, leveraging coherent DP-mQAM signaling for high-capacity transmission. It provides enhanced Tx optical power, low power consumption, and security features like AES-256 encryption, making it suitable for DCI, metro, and campus interconnects . Juniper PTX Series Routers offer modular and compact 400G and 800G routing options. The PTX12000 line delivers up to 43.2 Tbps per line card, with ZR/ZR+ optics on every port, deep buffering, inline MACsec, and flexible filtering. These routers are ideal for core, peering, data center interconnect, and AI data center networking .

Technology and Standards

400G optical routers utilize pluggable coherent optics such as 400ZR and 400ZR+, enabling high-density, cost-efficient deployment. These optics support short-reach single-span applications and longer-reach multi-rate links, bridging IP and optical networks efficiently . Pluggable modules allow network evolution without changing the optical interface, supporting breakout to lower-speed Ethernet interfaces and versatile diagnostics for link performance, including pre-FEC BER and SNR monitoring .
