IOEMA-1

IOEMA-1 is a submarine fiber-optic cable system connecting 5 countries across 7 landing points. The cable provides high-capacity connectivity for internet traffic, voice, and enterprise data between continents.

Modern submarine cables use Dense Wavelength Division Multiplexing (DWDM) technology to transmit multiple simultaneous light channels, dramatically increasing capacity without adding physical cables.

The cable is operated by a consortium of telecommunications companies. This joint ownership model distributes the substantial capital costs of construction and maintenance across multiple participants, with each operator receiving guaranteed capacity and indefeasible right of use (IRU) on the cable.

Submarine cables like IOEMA-1 form the critical backbone of the global internet, carrying over 95% of international data traffic. GeoCables monitors this cable's health and performance in real time using RIPE Atlas probes, comparing current RTT measurements against established baselines to detect network degradation as it happens.
