The new submarine cable map from @TeleGeography depicts 447 cable systems and 1,194 landing stations that are currently active or under construction. https://t.co/CVq3YTaKzG
The first successful trans-Atlantic telegraph cable between Heart’s Content, Newfoundland and Valentia, County Kerry, Ireland in 1866 was one of the major milestones in global communications and the birth of globalization. #WorldHeritageDay@RoeStafford@LenHobbs@seethesites
What a great video about telegraph cables landing at Mousehole. The Imperial Telegraph Cables at Mousehole https://t.co/dTeGa7YC9t via @YouTube Thanks for the heads-up from @CableHistory
#OTD 1961 Queen Elizabeth II opened the Anglo-Canadian telephone cable (CANTAT 1) laid by Post Office cable ship between White Bay, Newfoundland, Canada and Oban, Scotland, the first section of a subsea telephone network linking the Commonwealth. It was in operation until 1982.

@AsWeMaySink Paul: The design of telegraph cables didn't change much until after WWII. This one could be from the late 1800s into the 1930s, but if you look at V8 on the Valentia page it says the diversion was in 1934. My friend Donard's book is a key reference: https://t.co/ATRKPktaKl
There are lots of cables around Valentia, both across the Atlantic, and onward to various parts of Britain and Europe. This is not a long-distance cable, which have only one conductor. Some landing points were moved over the years, and this looks like a diversion connection.
