Dark Fibre
Unlit G.652D single-mode fibre in the Sofia metro today — reaching all data centres and business buildings across the city. Cross-border and national corridors are on our roadmap: Sofia–Kalotina in service mid-2027; Route A to Komotini in service Q1 2028. A second diverse route to the Greek border is under commercial negotiation. Onward reach to Frankfurt, Amsterdam and Marseille is partner-delivered from Kalotina once the corridor is live.
