The resources of cable providers and telephone companies are being stretched to the limit due to the addition of such items as second lines for children, computers, security and the advent of the “smart house.” This situation is compounded by the race to offer the telecommunications “triple play” – a combination of voice services; cable TV and video on demand; and high-speed data and Internet access. Until now, phone companies have lacked the video portion, since their existing copper infrastructure has had only enough bandwidth to support broadband and voice. For branch offices, small businesses and homes seeking such services, the traditional solutions offered by telecommunications companies have been T1 lines and DSL. T1 lines are often expensive and DSL has been plagued with performance issues. And with speeds hovering around the Mbps, neither technology offers the ability to fully support triple play. Enter Fiber-to-the-Premises (FTTP). The new FTTP technology is expected to solve this problem—transferring data at speeds from 622 Mbps to Gbps per second to users and 155 Mbps to 622 Mbps to the network—much faster than cable modems, T1s or DSL. According to analysts at In-Stat/MDR, the number of FTTP subscribers worldwide will grow at a compound annual rate of 49% between 2003 and 2007, by which time the cost of deploying fiber could drop to below $500 per subscriber. The North American rollout has begun and will reach completion over the next decade— taking place in both existing and greenfield developments. The purpose of this guide is to provide you an understanding of the issues surrounding FTTP. What are the challenges in FTTP implementations? When does it make economic sense? What should you be doing now to take advantage of the next phase of fiber .
