Terrestrial backbone connectivity (optical fibres, microwaves). The data for the World Transmission Links have been collected through: Primary sources: Reply to an official request for information (RFI) document has been sent to all Regions outlining the purpose of the project for operators, indicating what level of detail is required, and what format the data is to be published. Secondary sources: On data was readily available in the public domain, from operator websites, annual reports, company presentations, and presentations at industry conferences. Partnership: A number of organizations do already research and produce transmission network maps for particular countries or regions, for various technical reasons. The collection of data as well as their validation from concerned Operators/Administrations is currently a work in progress. This layer Includes extracts and a simplified metadata from the research conducted by ITU on backbone fibre and microwave links. For more information: https://bbmaps.itu.int.
