Architecture of Optical Subscriber Loop Cable Network

This paper describes the optical subscriber loop cable network configuration methods. In the transition from the present analogue telephone service to a future broadband integrated digital network (BISDN) service, various subscriber systems, classified as single star (SS) and subscriber multiplexed double star (DS) exist in the same subscriber network. Among the multiplexed subscriber systems are the passive double star (PDS) system which uses the star coupler, and the active double star (ADS) system which uses the central terminal and remote terminal.
