Japan-Guam-Australia North (JGA-N)

Japan-Guam-Australia North (JGA-N) is a point-to-point submarine cable linking Japan and Guam. Landing at Minamiboso, Piti, it provides a direct fiber-optic path between the two countries, serving as both a primary data route and a redundancy option for neighboring cable systems. As an intercontinental system, Japan-Guam-Australia North (JGA-N) plays a role in the global mesh of over 500 submarine cables that collectively carry more than 95% of international data traffic. GeoCables monitors this system's performance through regular RIPE Atlas probe measurements, analyzing RTT patterns to detect degradation before it impacts end users.
