An Island-wide SDH transmission network for the Ceylon Electricity Board

Abstract

Optical fibers are the choice of transmission medium for the high capacity telecommunication transmission systems of today such as Synchronous Digital Hierarchy (SDH), giving a very high yield for the investment made. With the already established highly reliable power transmission infrastructure, together with the advancement of technology, the utilities have a very high potential market in the telecommunication carrier service. By replacing the ground wires of the overhead high tension transmission lines with Optical Ground Wires (OPGW), utilities can build-up a country-wide high capacity transmission network over a relatively very short time frame and a very low investment. This paper analyses the possibility of establishing an island-wide optical fiber transmission network for the Ceylon Electricity Board based on the OPGW technique
