Long-haul backbone
Capacity & performance
Our national backbone relies on a homogeneous100G/400G DWDM architecture, deployed, operated, and maintained entirely in-house. The full route is documented and reflected in our GIS tools. Each link is measured, referenced, and monitored from our technical centers. The result: controlled latency, simplified capacity scaling, and guaranteed service continuity.
Metropolitan network
Dedicated Optical Local Loop
We operate a metropolitan network spanning more than 21,000 km, enabling the connection of critical sites close to business areas. Each connection relies on a dedicated local loop — no sharing, no third-party infrastructure.
Fibers are custom-configured and monitored end to end, ensuring maximum availability and full control over traffic flows.
Security & redundancy
Routes are diversified and access paths are duplicated when required by site constraints. Optical paths are designed to minimize single points of failure and ensure true redundancy. Our network is monitored 24/7, with stringent SLAs and a 4-hour MTTR delivered by our teams.
Data center & PoP interconnection
Our network is present in nearly 200 data centers across France and Europe, where we operate active Points of Presence (PoPs). These PoPs allow our partners to deploy their equipment, benefit from interconnection services (cross-connects, dark fiber, optical transport), and connect to other clouds or operators.
Each site is connected to our long-haul backbone and benefits from advanced redundancy options, including dual (or multiple) access paths and physically diverse optical routes. This extensive footprint enables us to deliver reliable, consistent connectivity across all locations.
A solid network, concrete solutions
Our in-house operated network is the technical foundation behind our fiber, transport, IP transit, and data center services.
Here’s how it is concretely deployed to meet your specific needs.
Access
FttO, accessible without compromise. Designed to become the standard for B2B connectivity.

Infrastructure operator, dedicated fiber, backbone… We clearly answer the most common questions about fiber infrastructure operators.
What is a fiber infrastructure operator? Unfold Fold
A fiber infrastructure operator deploys and operates a physical fiber-optic network. It builds the infrastructure — backbone, access network, data center connectivity, and more — and makes it available to service providers. At ielo, we control this entire technical chain, from network engineering and design through to field operations and day-to-day network management.
What’s the difference between an infrastructure operator and a commercial operator? Fold Unfold
The infrastructure operator owns and manages the network. The commercial operator, in turn, uses that network to deliver services (internet access, telephony, cloud services, etc.) to end customers. At ielo, our position is clear: we are neutral and independent, 100% wholesale-focused.
