Optical wavelength transport in France

ielo Wavelengths is a high-capacity optical service, designed and operated in-house by our technical teams. It allows you to transport data from 10 to 400 Gb/s, regardless of the protocol (Ethernet, OTU, Channel Fiber), over controlled routes, connecting your sites, data centers, or critical platforms with consistent performance.

Leveraging our long-haul and metropolitan networks, we rely on a dense national mesh offering a wide choice of routes to deliver your links both in data centers and directly to customer sites, anywhere in France.

Reliable, stable optical transport, continuously operated: the foundation of a backbone that keeps its commitments.

The ielo approach

High-performance, scalable wavelengths
available exactly where you need them.

Because your traffic goes beyond the data center, our wavelengths do too.

Your services require multiple routes. We have them.

12,000 km of long-haul network, 21,000 km of metropolitan network, and multiple routes on most axes. Your optical transport runs over truly distinct paths, designed to meet the resilience requirements of your critical environments.

Wavelengths delivered… everywhere!

With over 200 WDM nodes and multiple connection points per metro area, we deliver your capacity exactly where you need it: DC ↔ DC / DC ↔ Customer Site / Customer Site ↔ Customer Site.
A level of flexibility rare in the market, made possible by our full control of the infrastructure.

Your needs can evolve… and so can your ielo wavelength!

Because we control our long-haul network, WDM nodes, and routes, we can adjust your paths, bandwidth, or delivery points, according to the evolution of your architecture. With optical capacity scaling up to 96×400G per route (evolutive), your backbone absorbs traffic growth, data replication, and real-time flows without degrading performance.
