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 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.[4][5][6]
History
[edit]Alcatel Submarine Networks commenced the installation of the cable in October 2015, completing the process in January 2016. The cable entered commercial operation in May 2016.
In October 2017, a network switch was installed to the Finnish port city of Hanko.[7]
Fault in 2024
[edit]A fault was detected in the cable on 18 November 2024,[8] after which the services provided over the cable went down. According to the Finnish operating company 'Cinia Oy', the cable service was interrupted by a subsea physical force .[3] The fault was discovered off the coast of the Swedish island of Öland.[9]
German Federal Defense Minister Boris Pistorius called the incident an act of sabotage.[8] As of 19 November 2024, the cause of the fault was being investigated.[10][9]
The Lithuanian Naval Force announced increased surveillance of its waters in response to the damage and would discuss further measures with Lithuanias' allies.[8]
On 29 November 2024, the operator Cinia Oy announced that the cable had been completely repaired.[11]
