Fiber to the home (FTTH) architecture overview

Not all FTTH networks are built the same. Since construction and outside plant account for the majority of total network costs, getting the architecture right has a major impact on the business case.
 
The network architecture can also impact time-to-market, labor/training requirements, future upgradeability, network performance, and ultimately customer satisfaction. This paper provides an overview of two fundamental FTTH architecture categories—centralized and cascaded—that determines where in the network the fiber is split.
