(NEXUS MK VII (HD
The MacArtney NEXUS MK VII is an advanced and versatile HD video, standard video, Ethernet, serial and multibeam sonar multiplexer based on Focal 907 telemetric technology. Providing a highly efficent link between surface and seabed, the NEXUS MK VII carries all signals over one single mode optical fibre via CWDM (coarse wavelength division multiplexing).
The NEXUS MK VII is highly configurable and allows for an easy upgrade/modification path when operational or applicational requirements change. Multiplexer options can be installed between jobs or even at sea without the need for an electronics workshop.
Power switching is software controlled via PC software or using a tablet which is online via LAN or WiFi. Sensor power status, telemetry link, leak alarm etc. is also continuously monitored by the software. Advanced features include programmable fuses and software enabled interface selection. The protocol is open and can be integrated into customer software for monitoring convenience. A touch screen display on the topside front panel allows for easy monitoring of selected parameters during set-up and operation.
As standard, the subsea unit housing is manufactured from hard anodised aluminium. Connectivity interfaces include SubConn® anodised aluminium connectors, SubConn® coax (HD video) connectors and a MacArtney OptoLink fibre optic connector.
