Does anyone know if the optic fibre repeaters on the underwater submarine cable SEA-ME-WE3, which runs from Perth through the search area to Jakarta, emit any noise? They are powered by internal DC power. Could they be causing interference?
They shouldn't have any interference as they are high capacity datalinks and any interference would degrade the throughput. Those cables are normally covered in protective layers to shield any interference and then buried in a trench at the bottom of the ocean to further protect them.
