MacArtney Nexus MKIV Fibre Optic Multiplexer

The MacArtney NEXUS MK IV is replacing the successful NEXUS MK I, which has served the subsea ROV/ROTV market for 6 years since the introduction in 2000. The MK IV is the “MultibeamSonar Multiplexer” and does not interface video cameras. It is based on the MacArtney (P)ECL fibre optic converters, our Cypress multiplexer, MiniController and E2P ethernet converters. The new power switching of all the sensors is software controlled and combined with monitoring of sensor power status.


  • Interfaces all standard multibeam sonars and survey sensors
  • Supplies power to sensors. Software controlled
  • Operates on one singlemode optical fibre.
