The use of optical fibre to provide economic telecommunication in rural areas

Abstract

The optical fibre distributed concentrator (OFDC) allows the economic provisioning of voice and data services in rural areas. It is integrated into the Siemens EWSD digital public exchange. The OFDC consists of a central office terminal (COT) and one or more remote terminals (RTs). The RTs connect to an optical fibre loop which terminates at the COT. An example network is depicted and described.<>
