Estimated cost of a submarine fiber cable system

This report is based on published cost figures of the TAT-6 submarine coaxial cable system which went into service on July 27, 1976. Assuming readiness of long wavelength (1300 nm) devices by the late 1980s, we project the expected cost of a fiber cable system based on the TAT-6 experience. The study shows an expected normalized cost savings (dollar per channel kilometer) of 37 to 52 percent, in constant dollars.
