This whitepaper provides a comprehensive analysis of the economic viability of various broadband network architectures in the evolving connectivity landscape. With an increasing demand for high bandwidth, network operators are exploring efficient ways to deploy fiber to homes and businesses across diverse geographical regions. The study examines three primary architectures: the traditional chassis-based PON (PMO1), the closed pizza box PON (PMO2), and the Ciena broadband solution powered by integrated router,  uOLT and coherent pluggable (FMO). The evaluation focuses on the total cost of ownership (TCO), considering not only the initial capital expenditures (CapEx) but also the operational expenses (OpEx) over time.
