AquaLink Deep-Sea Communication Relay Deployed in Mariana Trench: Real-Time Data at 10,000 Meters

DeepComm deployed AquaLink deep-sea communication relay chains in the Mariana Trench, using a hybrid acoustic-and-fiber architecture to achieve real-time data transmission at depths exceeding 10,000 meters, with bandwidth reaching 10 Mbps.

Ocean communications company DeepComm announced on April 30 the successful deployment of its AquaLink deep-sea communication relay chain in the Mariana Trench. The link stretches from Midway Island to Guam, traversing the trench's deepest point. Using 12 acoustic relay nodes and fiber-optic connections at critical segments, the system achieves real-time data transmission at depths beyond 10,000 meters.

Traditional underwater acoustic communication offers bandwidth of just a few kilobits per second, with signal degradation worsening over distance. AquaLink's multi-hop relay architecture combined with AI-powered signal processing boosts throughput to 10 Mbps — sufficient for live high-definition video feeds.

AquaLink's first users include deep-sea research stations and seabed mineral exploration companies. DeepComm plans to expand the AquaLink network to the world's major ocean trenches by 2032.
