Purchase an OTN router 400G

ODN and passive infrastructure knowledge brief Published 20 Feb 2023

Prepared for preliminary research by the GESTIONVAL ODN knowledge desk. Confirm network topology, split ratio, box or cabinet capacity, joint closure rating and loss budget against current standards and product documentation.

You can acquire 400G-capable OTN routers from vendors like Cisco, Huawei, Adtran, and Nokia, each offering modular platforms with pluggable coherent optics for metro, DCI, and long-haul applications.Cisco Options

Cisco offers 400G QSFP-DD High-Power (Bright) Optical Modules that support both Ethernet and OTN clients. The multirate variant (DP04QSDD-HK9) supports ODUFlex, OTUCn/FlexO-x frame structures, Layer-1 authentication, and AES-256 encryption for secure OTN transport, making it suitable for high-capacity metro and DCI networks . For ultra-long-haul applications, Cisco's 400G QSFP-DD ULH Coherent Optics Module extends reach over DWDM networks while maintaining spectral efficiency and compatibility with existing 400G-capable routers .

Huawei Options

The Huawei OSN9800 is a next-generation OTN platform supporting 100G, 200G, and 400G per wavelength. It features a modular design with high integration, enabling service access from 100M to 100GE and smooth expansion to 1T/2T. The platform supports OTN, VC, and packet switching, and integrates MPLS-TP for cloud-era scalability .

Adtran Options

Adtran's FSP 3000 OpenFabric™ Series provides a flexible, open switchponder platform with 400G pluggable coherent interfaces. The OpenFabric1200™ card supports multiple OTN and Ethernet services from 10G to 400G, enabling cost-efficient metro aggregation and easy upgrades of legacy infrastructure . Optional AES-256 optical encryption is available for secure transport.

Nokia Options

Nokia's PSE 100G/400G pluggable coherent optics (e.g., QDDCO4Z) support multi-vendor interoperability and OpenZR+ standards. These modules enable 400G tunable WDM transmission with single-span unamplified reach up to 40 km and amplified multi-span operation up to 120 km, suitable for metro, DCI, and broadband backhaul applications .

Key Considerations
  • Deployment Type: Metro, DCI, or long-haul networks influence module choice (e.g., Cisco ULH for long-haul, QSFP-DD for metro/DCI).
  • Pluggable Optics: QSFP-DD modules provide flexibility for upgrading existing routers to 400G.
  • Security: AES-256 encryption and Layer-1 authentication are available on several platforms for secure OTN transport.
  • Scalability: Modular platforms like Huawei OSN9800 and Adtran FSP 3000 allow smooth expansion from 100G to 400G and beyond.
  • Compatibility: Ensure the router supports the desired coherent optics standard (400ZR, OpenZR+, or ULH) and multi-rate OTN frames. For purchasing, you can contact authorized distributors or vendors directly through their product pages: Cisco QSFP-DD 400G modules, Huawei OSN9800, Adtran FSP 3000, and Nokia PSE 400G optics .
