Overview

When standard networks aren't enough

As data volumes grow and applications become more critical, businesses need connectivity that delivers absolute control, performance, and security. Shared or off the shelf network services often fall short when supporting data centre interconnection, disaster recovery, cloud environments, or data intensive workloads. Colt Private Wave, also known as MOFN (Managed Optical Fibre Network), solves this by providing a fully managed, customer dedicated optical network designed for scale, resilience, and long term reliability.

Benefits

Benefits that empower progress

True Dedicated optical infrastructure
Private Wave (MOFN) gives customers an exclusive optical network built on fully dedicated fibre and WDM equipment — never shared with other users. This delivers uncontended capacity, predictable performance, enhanced security, and complete design control, enabling architectures and service combinations that shared wavelength or packet‑based services simply cannot support.
Unmatched Performance + Stability
Private Wave (MOFN) delivers deterministic, low latency optical performance with scalable capacity from 1Gbps to 400Gbps and beyond on a single infrastructure. Customers can consolidate multiple services and protocols while expanding capacity seamlessly as demand grows — without re architecting the network.
Sovereign Control + Custom Design
MOFN gives customers full control over network design, topology, vendors, and upgrade paths. This enables sovereign networking architectures tailored to regulatory, security, and business requirements — going far beyond the constraints of standardised packet or off‑the‑shelf wavelength services.
Built for Mission-Critical Workloads
Private Wave (MOFN) is engineered for the most demanding use cases, including data centre interconnection, disaster recovery, AI, and high‑performance computing. With dedicated infrastructure, advanced resilience options, and optional encryption, customers achieve maximum availability, data protection, and business continuity.
