Submarine Communications Cable
Submarine Communications Cable is a cable laid beneath the sea to carry telecommunications between countries. The first submarine communications cables carried telegraphy traffic. Subsequent generations of cables carried first telephony traffic, then data communications traffic. All modern cables use fiber optic technology to carry digital payloads, which are then used to carry telephone traffic as well as Internet and private data traffic.
