2. HK-G cable has been withdrawn due to the FCC license.
3. Google considers Blue-Raman cable as separate Blue and Raman cable systems.
Google has owned and invested in five private subsea cable systems. Junior cable is technically Google’s first private owned subsea cable. But Junior cable is a domestic subsea cable connecting Rio de Janeiro to Santos in Brazil. Curie, Dunant, Equiano, Grace Hopper and Firmina are international cables.
