An optical system architecture intended to provide subscriber access for future network sevices must also support existing services at a cost equivalent to copper. An integrated optical‐fiber system which meets this criterion and provides both CATV and telephone service has been designed under contract to the Deutsche Bundespost and is planned for pilot installation early in 1990 in Köln, Federal Republic of Germany. A bus network was chosen for implementation of the trial system because of the advantages it provides over a point‐to‐point star network. Economies result from using much less fiber per subscriber, and from the sharing of optical transmitter and receiver costs among many subscribers. The telephony portion of the system initially provides existing telephone service based on digital transmission technology yet is configured to support the development of new services. The CATV portion of the network is designed to be functionally equivalent to the coaxial system now being deployed, but offers advantages in reliability and future expansion possibilities. The implementation of a system using a bus architecture to provide network access for telephone and broadband CATV services over optical fiber cables is described.
