A+T Instruments has ESP Ethernet over Ships Power; B&G has FastNet; Furuno has NavNet ("NavNet" refers to a product family, and is not a communications protocol. Furuno uses industry standard NMEA 0183, NMEA 2000, and standard Ethernet for communications protocol in their products) Mastervolt has CZone; Nexus has FDX; Raymarine has Seatalk ...
A cable layer or cable ship is a deep-sea vessel designed and used to lay underwater cables for telecommunications, for electric power transmission, military, or other purposes. Cable ships are distinguished by large cable sheaves [ 1 ] for guiding cable over bow or stern or both.
8 – Optical fibers Submarine cables are laid using special cable layer ships, such as the modern René Descartes , operated by Orange Marine. A submarine communications cable is a cable laid on the seabed between land-based stations to carry telecommunication signals across stretches of ocean and sea.
The SPIN personnel went on to develop the Hawaiki Cable [13] [14] (see List of international submarine communications cables), which started commercial operation in 2018. [15] Cable landing points were proposed for Auckland, Norfolk Island, Noumea, Suva, Wallis, Apia, Pago Pago and Papeete, with a branching unit for Vanuatu.
NMEA 2000, abbreviated to NMEA2k or N2K and standardized as IEC 61162-3, is a plug-and-play communications standard used for connecting marine sensors and display units within ships and boats. Communication runs at 250 kilobits-per-second and allows any sensor to talk to any display unit or other device compatible with NMEA 2000 protocols.
An example is the cable between Singapore and Indonesia, which was partly robbed in 2013: 31,7 km and 418 tons of cables were removed. [33] Another scenario is a criminal group threatening to harm cables if no ransom is received. Last, cables could be damaged to cover an unrelated criminal attack, as it would diminish surveillance capacities. [34]
Submarine cable is any electrical cable that is laid on the seabed, although the term is often extended to encompass cables laid on the bottom of large freshwater bodies of water. Examples include: Submarine communications cable
Land cables and submarine cables were installed between 2020 and 2023. In 2023 the cable laying contractor Prysmian announced that the land cables and 870 km of the 1250 km dual subsea cable had been laid with the remaining 380 km subsea cable to be laid between April and July 2023. [16] The undersea section of the link was completed in July 2023.
