ABOUT SMART CABLES

WHAT IS A SMART CABLE?
SMART (Science Monitoring and Reliable Telecommunications) cables are telecommunications cables designed to deliver real-time remote sensing of the ocean floor alongside traditional telecommunication objectives.
A global SMART Cable initiative has been exploring a number of ways in which these sensors could be integrated into commercially standard telecommunication cables to create SMART cable systems.

WORLDS' FIRST SMART CABLE
The 'demonstrator' project proved that, with the appropriate selection of instruments, cable repeaters could be retrospectively fitted with seismic instrumentation; laid using traditional cable laying methods and; coupled sufficiently with the sea-floor to deliver good quality seismic data.

THE IMPORTANCE OF
INSTRUMENT SELECTION
Traditional broadband seismic sensors can withstand a tolerance of just a few degrees from level, or they require gimbals that will re-orientate them. Güralp’s broadband seismometer addresses this issue using novel and unique technology.

ADVANCED SENSOR TECHNOLOGY
This feature makes them the ideal choice for challenging deployments such as cable deployments from a ship. We also have demonstrable success with these same sensors in our traditional ocean bottom systems with excellent results.
In addition to our seismic sensors, we can also incorporate research grade temperature sensors for monitoring sea floor oceanographic conditions and absolute pressure gauges (APGs) for tsunami warning systems.

COMPARISONS WITH TRADITIONAL SEISMIC OBSERVATORY
Power Spectral Density (PSD) plots were created from the SMART cable Certimus units and from the CALIPSO system and compared.
Generally, the PSDs show close coherence, particularly out to a period of 20 seconds. This shows that a seismic sensor package using our omni-directional sensors installed in a repeater housing that has been deployed using a standard commercial method, provides comparable data quality to a dedicated offshore seismic observatory.
