About the JUNO Cable System

JUNO is a point-to-point submarine cable linking United States and Japan. Landing at Grover Beach, Minamiboso, Shima, 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. The transpacific route is one of the busiest data corridors in the world, carrying financial, cloud, and content delivery traffic between Asian and American markets. This cable is part of GeoCables' continuous monitoring program — RIPE Atlas probes measure latency around the clock, flagging anomalies when RTT deviates significantly from established baselines.
