Although FTTP is receiving a great deal of attention for delivering today’s bandwidth-hungry triple-play services to the home, many service providers are opting for a fiber-to-the-node (FTTN) access solution. FTTN takes advantage of existing copper infrastructure to provide a cost effective alternative – and ADC has developed an entire portfolio of FTTN service delivery solutions. | FTTN Service Delivery Option Challenges and Considerations Although FTTP is receiving a great deal of attention for delivering today s bandwidth-hungry triple-play services to the home many service providers are opting for a fiber-to-the-node FTTN access solution. FTTN takes advantage of existing copper infrastructure to provide a cost effective alternative - and ADC has developed an entire portfolio of FTTN service delivery solutions. These service delivery solutions cover numerous scenarios and situations including passive stand-alone architectures and active integrated solutions whereby the service delivery frame is actually embedded into an active cabinet. There is even a combo solution that provides FTTN delivery using one side of the cabinet with the provision to plug in 1x32 optical splitters on the opposite side for a fast future upgrade to an FTTP cabinet network architecture. This is a unique single cabinet solution for deploying FTTN today with a migration route to FTTP tomorrow. Each solution provides the technicians with a consistent look and feel approach to wiring within each cabinet making it easy to quickly identify key components and ports. These solutions offer monitor look-in look-out testing capabilities that help technicians quickly isolate any potential network problems. Like FTTP there are considerations and challenges to deploying successful FTTN solutions. There is no one size fits all solution when transforming the traditional switched approach network into a high-speed high-capacity broadband network. FTTN Service Delivery Option Challenges and Considerations Challenges to FTTN The first challenge facing FTTN deployers is the need to resectionalize the distribution areas DA . Today service providers are providing regular DSL or ADSL services to customers via a digital loop carrier DLC feeding through a cross box with a loop length in some cases that can have a loop length of up to 12 000 feet. But the introduction of VDSL or ADSL2 ADSL2
