The OEMOTN Router 400G is a high-capacity optical transport router designed for metro, regional, and data center networks, supporting 400G throughput with pluggable coherent modules and full OTN integration.

Key Features and Capabilities

High-Capacity Throughput: 400G routers like the OEMOTN support multi-rate services, enabling aggregation of large traffic volumes at the network edge or core. They can handle 400G Ethernet interfaces and often support 10G, 100G, and 400G simultaneously, allowing gradual capacity upgrades without service disruption . Optical Transport Integration: These routers typically use pluggable coherent modules such as CFP2-DCO or 400ZR/400ZR+ optics, enabling direct integration with DWDM networks. This allows long-haul, metro, and data center interconnect applications with distances ranging from 40 km (400ZR) up to 120 km or more with external amplification (400ZR+) and Multihaul DCO modules . Interoperability and Monitoring: OEMOTN routers provide full demarcation between service and OTN layers, offering visibility and performance monitoring for both optical transport and service interfaces. They are interoperable with third-party switches and routers, simplifying network expansion and multi-vendor deployments . Software and Operational Flexibility: Modern 400G routers integrate Layer 2 and Layer 3 capabilities, MPLS support, and software-based network operating systems for simplified management. This allows operators to consolidate residential, business, and mobile traffic on a single platform while maintaining high performance and reliability . Energy and Space Efficiency: By consolidating traffic onto fewer high-capacity interfaces, 400G routers reduce power consumption, rack space, and operational complexity, which is critical for dense metro and data center environments .

Applications

• Metro and Regional Networks: Aggregating traffic from fiber broadband, mobile backhaul, and enterprise connections.
• Data Center Interconnect (DCI): High-speed links between data centers using 400G coherent optics.
• Core Network Upgrades: Replacing multiple 100G links with fewer 400G interfaces to simplify network architecture.
• Cloud and Hyperscale Environments: Supporting leaf-and-spine architectures and high-density routing for IO-intensive applications .

Optical Module Options

• 400ZR: Short-reach, single-span 400G coherent optics for up to 40 km.
• 400ZR+: Extended reach and flexible line rates (100G–400G) for metro and regional networks.
• CFP2-DCO / Multihaul DCO: Modular transceivers for longer distances and higher optical performance, supporting advanced forward error correction and bypassing multiple ROADMs .

Summary

The OEMOTN Router 400G is a versatile, high-performance solution for modern networks requiring 400G throughput, OTN integration, and flexible optical transport options. It enables service providers and data center operators to scale efficiently, reduce operational complexity, and support a wide range of services while maintaining interoperability and monitoring capabilities .
