#Submarinecablemap
There are 600 + active or planned #submarinecables worldwide. Maps such as #Submarinecablemap keep track of many. The cables contain sensitive #fibre optics that transmit #digitalinformation using light pulses.

I only find SE, DK and DE on submarinecablemap. You sure about FI?

It is marked ”comms” in the MT chart and on the schematic submarinecablemap. Electrical and quite detailed in your link.

Your link seem more trustworthy.

Lovely visualization, well done!

Have you recently compared OSM's subsea telecom data with submarinecablemap? The community seems to have made some big strides forward accuracy wise in the Baltic but I haven't compared with the Irish Sea.
