Metro & Regional DWDM
Delivering high-capacity, low-latency optical transport for metropolitan networks, connecting enterprises, data centres, cloud platforms and service providers with scalable infrastructure designed for future growth.
Optical Transport Networks are at the core of Terrabit Networks' engineering heritage, delivering secure, high-capacity and resilient connectivity for enterprises, service providers, governments and critical infrastructure. Our carrier-grade optical solutions maximise fibre utilisation, support future network growth and enable seamless technology evolution across metro, backbone, subsea and data centre environments.
What we deliver
Core capabilities
Long-Haul Optical Backbone
Building resilient national and regional backbone networks that provide high-capacity transport, cross-border connectivity and long-term scalability for mission-critical infrastructure.
Subsea Optical Networks
Providing end-to-end engineering services for submarine cable systems, including Cable Landing Station integration, terrestrial backhaul, deployment, migration, testing and commissioning.
Data Centre Interconnect (DCI)
Enabling secure, high-speed optical connectivity between enterprise, cloud and hyperscale data centres to support AI workloads, disaster recovery, storage replication and business continuity.
ROADM & Open Line Systems
Designing flexible, open optical architectures with dynamic wavelength routing and multi-vendor interoperability, allowing networks to scale efficiently while protecting long-term investments.
Optical Monitoring & Assurance
Providing real-time visibility, performance monitoring and proactive assurance to optimise network health, accelerate fault resolution and maximise service availability.
Scope of expertise
Our domains include
High-Capacity Optical Transport Architectures
Move more data across a flexible optical foundation.
High-capacity optical architectures connect data centres and network locations as traffic grows. Our scope includes Data Centre Interconnect, ROADM and open line systems, with wavelength routing planned around the required connectivity.
Multi-vendor interoperability and expansion needs are considered in the design, helping organisations develop an optical platform that can accommodate changing capacity and routing demands.
In this domain
- Data Centre Interconnect (DCI)
- ROADM and open line systems
- Dynamic wavelength routing and multi-vendor interoperability
Metro and Backbone Optical Networks
Connect the metro, the region and beyond.
Metro, regional and backbone networks must carry rising traffic over different distances and operating conditions. We support DWDM and long-haul architectures, including cross-border networks, subsea systems and their terrestrial backhaul.
Planning considers capacity, network resilience and the interfaces between these systems, so connectivity can be delivered as a coherent end-to-end service.
In this domain
- Metro and regional DWDM
- Long-haul and cross-border backbone networks
- Subsea systems, cable landing stations and terrestrial backhaul
Optical Access Networks
Create room for growth at the network edge.
Enterprise and service provider access networks need dependable optical connectivity between sites and services. We help plan fibre utilisation and capacity around existing demand, available resources and future expansion.
A scalable approach to access design supports new locations and services while making effective use of the optical infrastructure already in place.
In this domain
- Optical connectivity for enterprise and service provider environments
- Fibre utilisation and capacity planning
- Scalable network expansion
Optical Testing, Monitoring and Performance Assurance
Understand performance throughout the network lifecycle.
Testing and commissioning establish whether an optical network is ready for service. We support deployment and migration activities alongside performance validation and operational visibility.
Monitoring and proactive assurance help teams identify degradation, investigate faults and prioritise corrective action, connecting the initial implementation with ongoing network performance.
In this domain
- Deployment, migration, testing and commissioning
- Real-time network visibility and performance monitoring
- Proactive assurance and fault resolution
From planning and design through deployment, optimisation and ongoing operations, Terrabit Networks delivers optical transport infrastructure engineered for reliability, scalability and long-term performance - supporting the networks that power today's digital economy while preparing organisations for tomorrow's demands.
