Submarine communications cable. A cross section of the shore-end of a modern submarine communications cable. 1 – Polyethylene 2 – Mylar tape 3 – Stranded steel wires 4 – Aluminium water barrier 5 – Polycarbonate 6 – Copper or aluminium tube 7 – Petroleum jelly 8 – Optical fibers. Submarine cables are laid using special cable ...
NMEA 2000. 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 ...
A transatlantic telecommunications cable is a submarine communications cable connecting one side of the Atlantic Ocean to the other. In the 19th and early 20th centuries, each cable was a single wire. After mid-century, coaxial cable came into use, with amplifiers. Late in the 20th century, all cables installed use optical fiber as well as ...
Ethernet cable with an M12 X-coded connector in one end and a modular connector in the other. IEC metric screw sized connectors is a family of electrical connectors defined by IEC that are named according to their ISO metric screw thread, namely M5, M8 and M12. [1] The number gives their outer screw thread diameter in millimeters as with the ...

An Ethernet crossover cable is a crossover cable for Ethernet used to connect computing devices together directly. It is most often used to connect two devices of the same type, e.g. two computers (via their network interface controllers) or two switches to each other. By contrast, straight through patch cables are used to connect devices of ...
Three submarine power cables cross Cook Strait between Oteranga Bay in the North Island and Fighting Bay in the South Island as part of the HVDC Inter-Island, which provides an electricity link between Benmore in the South island and Haywards in the North Island. Each cable operates at 350 kV, and can carry up to 500 MW, with Pole 2 of the link ...
Ethernet over twisted-pair technologies use twisted-pair cables for the physical layer of an Ethernet computer network. They are a subset of all Ethernet physical layers. Early Ethernet used various grades of coaxial cable, but in 1984, StarLAN showed the potential of simple unshielded twisted pair. This led to the development of 10BASE-T and ...
