This document discusses fiber-to-the-x (FTTx) deployment trends and technologies. It finds that deploying fiber to the most economical point (FTTdp) using a combination of technologies like fiber-to-the-curb with VDSL2 vectoring provides the best balance of cost, speed, and time to market compared to either full fiber-to-the-home or relying solely on copper broadband. Specifically, an analysis of two deployment options over a 10-year period showed that initially deploying VDSL2 and later upgrading to FTTH had a shorter payback period and higher cumulative discounted cash flow than only deploying FTTH from the start.
