Abstract :
In this paper, the authors propose the most suitable passive double-star network (PON) configuration for multiplexing more than two kinds of broadband service by wavelength division multiplexing (WDM) in optical access networks. They calculate the cost and number of facilities in outside plant and central offices by using the latest cost trend and investigate their dependence on certain structural conditions such as the number of splits, network configuration, and fiber structure, and service conditions such as multiplexing service number and service penetration. Moreover, the required network configuration for multiplexing more than three services was investigated. As a result, the most suitable PON network for cost-effective service provision and fiber to the home (FTTH) deployment was determined
