The TSS 350 Cable Survey System has been developed to meet this requirement in a compact, modular system that provides advanced features whilst remaining easy to use. With a low frequency electroding tone applied to the cable, the system can be used to locate cables buried beneath the seabed and to establish their burial depth. With modern subsea cable systems becoming increasingly sophisticated and their deployment, recovery and repair a more exacting science, there is a need for accurate subsea cable location. The IOEMA cable system consists of a trunk route, connecting Dumpton Gap, UK with Kristiansand, Norway and three branches, connecting. The European project SUBMERSE demonstrates how submarine fiber cables can act as scientific instruments in seismology, oceanography and marine biology, while also warning against cable intrusions. Nordic NRENs and NORDUnet play leading roles. Together with purpose built vessels and in-house surveyors this enables us to offer a range of survey services as subcontractors as well as full contracts. Among other, we can offer: • CABLE ROUTE SURVEYS: We perform. A fibre optic cable is a type of cable that uses light to transmit data as signals through thin glass or plastic fibres. Fibre optic cables are made up of multiple layers.
