The technological benefits of digital loop carrier using fiber facilities

The first step toward an all-fiber loop plant, namely, fiber-feeder deployment, is discussed. Modern fiber multiplexers and digital carrier systems offer technology designed for the outside plant environment, to provide a cost-effective vehicle for early deployment, while establishing a base for future narrow and broadband ISDN services. A fiber-feeder system also makes it feasible to move toward an all-fiber distribution system with capabilities such as video. System architecture and deployment arrangements are described.<
