Fiber optics networks or communication satellites: Alternatives?
Abstract
Trends in communication technology are surveyed, and the roles of fiber optics and satellite based systems are predicted. Economic factors are seen as predominant in the choice of system. Fiber optics, in the short term, are becoming cost competitive with coaxial cables and microwave techniques over short distances and high channel densities. This trend is expected to continue, with fiber optics becoming a dominant. The relative maturity of space system technology makes large cost reductions through technological breakthroughs unlikely, so satellites remain economically viable only for very long distance links. The projected fiber optic transatlantic cable may be cost competitive with Intelsat satellites. The main advantage of satellite systems is their capacity to test services before they are implemented in terrestrial networks.
