Spectrum as a Service

Optical Spectrum

Your own 112.5 or 150 GHz of dedicated spectrum on our DWDM line system. You run your transponders and choose the modulation and the capacity; we run and monitor the line. Available across our DWDM network from 17 PoPs, priced per route. 800G is available today in the 112.5 GHz slot, after we measure the line parameters on your route.

Key Features

Your optics, your capacity

You choose the transponder, the modulation and the line rate. The capacity you get out of the slot is decided by your equipment, not by a product tier.

Upgrade without a new order

When a new generation of coherent optics arrives, you swap the transponders at both ends inside the same slot. No new circuit, no new contract.

112.5 GHz and 150 GHz slots

112.5 GHz fits 800G-class coherent optics. 150 GHz leaves room for next-generation optics. Actual reach and rate depend on your optics and on the route.

800G after line measurements

Before we confirm 800G on a route, we measure the line parameters on that specific route and share the results, the launch-power targets and the optical budget with you. You know what your optics will see before you order.

Reserved and isolated

The slot is reserved for you on every span of the route. No other channel shares it, and your traffic never leaves your own optics.

Line monitored 24/7

Our NOC monitors the amplifiers and the line around the clock. If you would rather not run optics, take a managed wavelength of up to 400G instead.

Use Cases

AI cluster interconnect

Move training data and checkpoints between AI sites at the rate of the newest coherent optics, and upgrade capacity on your own schedule.

Cloud and content backbones

Run your own long-haul optics between regions while we keep the line system running.

Carriers

Extend your optical network across Southeast Europe and the Caucasus without building a line system of your own.

Coverage

Available in these cities

Delivered on our own DWDM line system, from 17 PoPs. Dubai is reached through a long-haul partner; spectrum on that leg is on request.
