TAILIEUCHUNG - The Economics of FTTN vs. FTTP

There are three predominant schools of thought regarding how to meet the everincreasing bandwidth needs of consumers and businesses. Fiber-to-the-premise (FTTP) architectures take optical fiber all the way to the home or office and offer the most future-proof solution in terms of pure bandwidth capabilities. But in some cases, FTTP may not be the optimal solution in terms of overall cost and the value of existing infrastructure. | The Economics of FTTN vs. FTTP The Economics of FTTN vs. FTTP There are three predominant schools of thought regarding how to meet the everincreasing bandwidth needs of consumers and businesses. Fiber-to-the-premise FTTP architectures take optical fiber all the way to the home or office and offer the most future-proof solution in terms of pure bandwidth capabilities. But in some cases FTTP may not be the optimal solution in terms of overall cost and the value of existing infrastructure. Fiber-to-the-node FTTN solutions offer operating companies an alternative solution to providing the necessary bandwidth required by today s voice data and video services while taking advantage of existing infrastructure. In many cases FTTN can actually complement FTTP deployments. Finally there is a fiber-to-the-curb FTTC solution that boasts 80 Mbits sec to the home. Certainly the question surrounding this architecture is whether 80 Mbits sec will be adequate and for how long. At the end of the day the key consideration in choosing which architecture will work best for any provider boils down to bandwidth - now and in the future. This paper addresses several key considerations in helping service providers decide if FTTN makes sense for all or part of their network. For example if a high percentage of a provider s network is already designed using digital loop carrier DLC remote terminals it may make more sense to deploy FTTN from an economic standpoint. Traditional telephone service providers seeking to offer additional broadband services over an existing copper-based voice network may find FTTN more advantageous and less costly than building a new network that takes fiber all the way to the customer. The Economics of FTTN vs. FTTP The business case Every operating company must consider its own business case in relation to the capabilities of the existing network. Since an FTTN strategy seeks to leverage existing facilities as much as possible it will ultimately come down to what .
