Description

The MacArtney Nexus MK IV is a multi beam sonar multiplexer that carries all signals over one single mode optical fibre via CWDM (Coarse Wavelength
Division Mulitplexing). The system encompasses MacArtney (P)ECL fibre optic converters, the Cypress multiplexer, MiniController and Ethernet converters.

Power switching on the MacArtney Nexus MK IV is software controlled and can be installed on any computer with at least one com port (real or USB). The protocol is open and can be integrated into customer software for monitoring convenience. Sensor power status, leak, link, etc, are also continually monitored through the software.

The subsea housing is manufactured from hard anodised aluminium and uses anodised aluminium SubConn® connectors. For depth ratings over 3000 MSW, the pressure vessel is manufactured from Titanium or high tensile Duplex steel.
