This paper presents some engineering and economic comparisons of several fiber‐based network architectures providing narrowband, and in some cases broadband, services in the subscriber loop. Specifically, comparisons are made between different bus and star configurations in the sub‐feeder plant using asynchronous transfer mode (ATM) network components. The study reports in detail an engineering cost model used to determine the installed first cost of several access architectures, including several fiber‐to‐the‐curb approaches which interface to the existing copper drop. The results show that these approaches can reduce the initial first cost of fiber installation, although other issues regarding network operations, maintenance, and evolution still need to be addressed.
