It is just ten years since the first experimental undersea fibre optic cables and prototype repeaters were installed. In those ten years, the technology advances have been such that the major oceans of the world have been crossed by fibre optic links and the information capacity has expanded from 5520 telephone circuits in the highest capacity analogue cable to 30.720 circuits potential in a 4 fibre pair 560 Mbit/s optical cable, even before use of circuit multiplication techniques. Submarine cable systems continue to present a major challenge by requiring state-of-the-art performance in an operating environment which imposes exceptional and abnormal constraints on system design.
