ITU has two current maps of fiber: one submarine cables a la the old Telegeography dataset, and also an intra-continental version aka inland-fiber routes. Try to get at that data as geojson? Or mmdb database? Something inbetween?
Maybe the ITU data server for WMS.
REST API?
Here’s a URL that returns valid json:
looks like totalFeatures: 40371, so setting maxFeatures to that gets the whole data set.
