CTEK Subsea Multiplexer

The CTEK Multiplexer is a high-performance data acquisition and transmission system engineered for the rigorous demands of underwater operations. Designed to interface seamlessly with navigation, hydrographic, and video equipment on various classes of underwater vehicles, this system ensures reliable communication between the seabed and the surface.


The system comprises two distinct components: a Subsea Unit (SU) that interfaces directly with mounted equipment for data encoding and power supply , and a Topside Unit (TU) that manages data decoding, control commands, and status monitoring. Rated for depths of up to 3000 meters, the CTEK Multiplexer offers a robust, service-friendly solution for complex subsea missions.
