Optical Spectrum
Your own 112.5 or 150 GHz of dedicated spectrum on our own DWDM network in Bulgaria. You run your transponders and choose the modulation and the capacity; we run and monitor the line. Available from 7 PoPs, priced per route. 800G is available today in both slots, 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, as long as the new optics fit its width. No new circuit, no new contract. Optics that need more spectrum move to the wider slot.
112.5 GHz and 150 GHz slots
The 112.5 GHz slot carries 800G on current-generation coherent transponders. The 150 GHz slot carries 800G pluggable optics (800ZR/ZR+) and next-generation optics at higher symbol rates. Reach and rate depend on your optics and on the route; on the longest routes the achievable rate can be lower than 800G. Spectrum is delivered as a fixed passband through dedicated optical filtering; the usable bandwidth after filter cascading on the route is confirmed in the line measurement.
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 passband 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 Bulgaria without building a line system of your own.
Available in these cities
Delivered on our own DWDM network in Bulgaria, between 7 PoPs with our own equipment. Not offered at partner PoPs.
