PRODUCT DESCRIPTION

In high-performance data centre networks, uptime is non-negotiable and early fault detection is key to avoiding costly outages. The VIAVI ONMSi (Optical Network Management System) provides 24/7 remote fibre monitoring and test capabilities across your entire fibre plant, from internal links to multi-site backbone routes.

Designed to support point-to-point infrastructure and dark fibre applications, ONMSi uses compact, rack-mounted Fibre Test Heads (FTHs) with built-in OTDRs to continuously assess fibre health, detect degradation, and localise faults with metre-level precision without disrupting live traffic. Whether you manage a single facility or multiple data centres, ONMSi scales to thousands of fibres with centralised control and smart domain management.

For operators of enterprise, hyperscale, or colocation data centres, ONMSi accelerates incident response, simplifies maintenance planning, and enforces infrastructure quality across owned and leased links. With detailed geolocation, smart alarms, and integration into existing NOC tools and ticketing systems, it reduces downtime, eliminates guesswork, and enhances long-term asset integrity.
