DWDM Wavelengths — transparent Layer-1 optical transport across Europe and Asia
21,500+ km backbone with scalable capacities up to 1,6TB per wavelength, diverse routing, and carrier-grade redundancy
Dedicated Layer-1 optical paths with predictable latency and no oversubscription.
Architecture-level routing control
Custom DWDM routing based on latency, compliance, or geographic diversity requirements.
No optical regeneration over long distances
Cleaner DWDM paths reduce latency and operational complexity.
Single-operator backbone responsibility
One optical backbone, one SLA, one operational owner end-to-end.

How the Service Operates
Use Cases
Our Wavelength Service is designed for network environments where architecture, latency, and operational control are critical. Typical use cases include:
Technical highlights
Service Types
Managed Wavelength
Fully managed DWDM wavelength service with GNM-provided optics, proactive monitoring, and end-to-end SLA ownership. Designed for customers who require predictable performance, operational simplicity, and a single point of responsibility for optical transport. Best fit: operators, enterprises, and cloud providers prioritising reliability over optical layer management.
Alien Wave
Integration of customer-owned transponders into GNM’s pan-regional DWDM backbone, enabling extended reach across long-haul and metro routes while retaining control over modulation and signal parameters.
Spectrum Lease
Lease of dedicated DWDM spectrum for customers building and operating their own transport layer. Provides full control over signal generation, modulation formats, and capacity planning, without reliance on provider-managed optics.
