Submarine Cables

Submarine Cables: Submarine cables use principles very much like those of coaxial cables. Thus they are coaxial, have repeaters and equalizers and have dc power fed to them, with opposite polarities fed from opposite ends to reduce insulation problems. However, Submarine Cables use a single coaxial tube for both directions of transmission, with frequency techniques […]

Multiplexing in Electronic Communication: Multiplexing in Electronic Communication is the sending of a number of separate signals together, over the same cable or bearer, simultaneously and without interference. There are generally two classifications. Time Division Multiplex, or TDM, is a method of separating, in the time domain, pulses belonging to different transmissions. Use is made […]
