The MacArtney NEXUS MK V multiplexer is based on the Focal 907 video/data multiplexer combined with the MiniController, Ethernet converters and the Focal Gb-media converters. Power switching of all sensors and cameras is software controlled and combined with monitoring of sensor power status.

The subsea housing is made from 7075 T6 hard anodised aluminium and the SubConn® connectors also represent the anodised aluminium type. For depth ratings over 3,000 MSW, the pressure housing can be manufactured from titanium or high tensile duplex steel.

The fibre optic telemetry takes advantage of the CWDM (coarse wavelength division multiplexing) technology and communicates all signals over just one singlemode optical fibre.
