These json files are used to plot https://www.submarinecablemap.com as can be seen from browser developer tools, so I'm assuming it should be up-to-date and consistent with the website?
Hey ! If available, can you please send me the dataset for the cables-map, unfortunately telegeography stopped maintaining their public github repo for downloads. Would really like to work on this dataset. If anyone can help, i would really appreciate the support !
