To modernize the survey multiplexor, Zupt developed the Zupt Mux. It is a compact network switch with serial and analog ports. Unlike conventional subsea multiplexors, the Mux provides a streamlined solution that works just as efficiently for minimal port requirements as it does for larger configurations, making it both cost effective and space efficient. Its user friendly topside interface removes the need for complex topside units. Only a computer and a 10 Gb Ethernet switch on the surface vessel are required for topside data communication.

As a subsea multiplexor, the Mux enables reliable fiber optic data transfer through a single cable from subsea sensors to the surface. An additional fiber port on the top end cap allows it to be daisy chained with other Mux units to expand subsea connectivity.

Engineered for the demands of offshore operations, the Mux delivers seamless data management in a compact, lightweight, and rugged package. Optimized for use on both ROVs and subsea structures/templates, it is the all in one fiber multiplexor where space, speed, and reliability matter most.a.
