NEXUS MK VI (HD)

The MacArtney NEXUS MK VI is a HD video and multibeam sonar multiplexer that carries all signals over one single mode optical fibre via CWDM (coarse wavelength division multiplexing). Options include (P)ECL and 10/100 Ethernet cards.

Power switching is software controlled and can be installed on any computer with at least one real or USB com port. The protocol is open and can be integrated into customer software for monitoring convenience. Sensor power status, leak alarm, telemetry link, etc. are also continuously monitored by the software.

As standard, the subsea housing is manufactured from hard anodised aluminium. Connectivity interfaces include SubConn® anodised aluminium connectors, SubConn® coax (HD video) connectors and a MacArtney OptoLink fibre optical connector. For depth ratings over 3,000 MSW, the pressure housing can be manufactured from titanium or high tensile duplex steel.
