C-Lion1 is a submarine communications cable between Finland and Germany. The cable is owned and operated by the Finnish telecommunications and IT services company Cinia Oy.[1] It is the first direct communications cable between Finland and Central Europe; previous connections have been through Sweden and Denmark.
The cable was damaged in November 2024, taking the cable offline between November 18 and November 28.[2] Some officials suspect the damaging was an act of sabotage.[3] The connection was offline again between December 25, 2024 and January 6, 2025 in connection with the 2024 Estlink 2 incident.[4][5]
The cable is 1,173 kilometres (729 mi) long and has eight fiber pairs with a design capacity of 120 Tbit/s and a maximum capacity of 144 Tbit/s.[6][7][8]
