Dark Fiber, the ielo way.

Your own optical infrastructure, over controlled, long-lasting routes.
For a backbone you truly control.

ielo dark fiber allows you to build your optical infrastructure over controlled, documented, and truly dedicated routes.

Designed for backbones, sensitive platforms, production environments, and critical interconnections, it gives you full control over your capacity, equipment, and future expansions.

With over 30,000 km of independent network — long-haul and metropolitan — you have a solid, scalable, and resilient foundation to design the architecture that will support your most strategic services.

The ielo approach

Your infrastructure is a strategic asset
where every route matters.

Because you deserve the best, discover our vision of dark fiber.

Truly dedicated optical routes

Passive optical pairs over controlled paths: up-to-date GIS documentation, OTDR reflectometry tests, and accurate inventory. You know exactly where your fiber runs — and why.

A resilient infrastructure by design

12,000 km of long-haul and 21,000 km of metropolitan network provide truly diverse routes. Ensuring connectivity remains operational, even in the event of an incident.

In-house engineering that ensures consistency

Planning, route selection, field surveys, documentation, monitoring: our teams design, operate, and manage your fibers with a high level of precision, ensuring real service continuity.
