Trang 2The lure of fiber-to-the-node (FTTN) solutions is compelling It offers 24 Mb/s service today with technologies on the horizon that promise more As compared to fiber-to-the-premise (FTTP) overbuilds, FTTN requires one fifth the capital investment and one quarter of the deployment time, according to industry analysts Most compelling is the prospect of reusing existing copper distribution and feeder plant—all of which might be nearly or fully depreciated For greenfield projects, the business case for FTTP remains strong due to capital and operating cost parity and long infrastructure service life from the virtually unlimited bandwidth of optical fiber Still, for the other 80+ percent of carrier serving areas with copper-fed neighborhoods, FTTN offers a cost effective architecture for advanced services delivery
Re-sectionalizing distribution areas to achieve loop length goals can pose challenges to network planners, making the FTTN project vulnerable to hidden operating and capital costs Here are just a few of the questions that impact planning
• Are cross boxes and DLC cabinets at full capacity?
• What is availability of spare binding posts in cross boxes?
• Is there space or right of way for placing new adjunct DSLAM and/or cross box cabinets?
• Are multiple cross boxes now being supported from a single DLC cabinet?
• In low density areas, is there an interface point available to gain access to dial tone? Should you use dedicated DSLAM ports in these areas?
• What is the operating impact of more cabinets to manage?
In addition, there are other outside plant challenges that arise from re-sectionalizing distribution areas, partly due to more cabinets to manage and more services to provision and maintain In the FTTN network, how can you:
• Reduce truck rolls and failure frequency rates?
• Speed service turn-up?
• Retain high value subscribers?
• Reign-in operating expenses?

Challenges for FTTN Network Planning
An Attractive Solution for Broadband Service Delivery
Trang 3Key Technologies
ADC enables you to make full use of the existing copper outside plant in neighborhoods with FTTN architecture Each of ADC’s OmniReach® FTTN solutions helps reduce capital requirements and ensure lower operating costs for the long term through use of proven, advanced technologies
LSA-PLUS® IDC Termination Blocks
Silver plated, 45-degree angled insulation displacement contacts (IDC) provide superior grip that resists loosening and remain gas tight, improving reliability and bandwidth throughput
ComProtect® Combines direct connection or cross connection with DSLAM circuit protection in the same footprint, saving valuable space
in cabinets and creating more room for active equipment
"Look Both Ways"
Built-in “look both ways” monitoring ability allows circuit test in either direction without lifting wires, speeding service turn-up and reducing troubleshooting time
Integrated Cable Management
Integrated cable management for proper
storage of jumpers and cable in service
delivery cabinets ensures network reliability
Trang 4ADC Offers a Complete Portfolio of FTTN Solutions
Using these advanced technologies, ADC allows planners to inject broadband into the network according to the unique requirements of each distribution area by using OmniReach® NCX-1000 cabinets featuring patented Distribution Intercept (DI) for xDSL service delivery The DI-enabled NCX-1000 is spliced into the network so that feeder or distribution plant signals are intercepted using ADC’s advanced LSA-PLUS connectivity solutions Now, xDSL service delivery is performed from a single DI-enabled cabinet location by grooming any broadband service onto any subscriber circuit using a 2-pair jumper on a cross connect distribution field
The NCX-1000 with DI can be deployed as a passive cabinet placed between a legacy DLC cabinet and/or new adjunct DSLAM cabinet and one or more cross boxes in the feeder network It can also be strategically placed in the distribution network between one or more cross boxes and premises to achieve optimum bandwidth requirements
ADC’s key technologies support other design options, too Operating companies can reclaim up to 50 percent of cabinet space by replacing traditional 5-pin protection with ComProtect modules and LSA-PLUS connectivity Alternatively, for quick deployment deep in the network, ADC offers a series of pole or ground mounted NCX-1000 passive cabinets with integrated DI designed to work with the new breed of hardened DSLAMs Finally, there is a hybrid platform for provisioning FTTN or FTTP services from a single cabinet The OmniReach N2P cabinet solution may be used simply to position target distribution areas for migration to FTTP or to serve brownfield/greenfield applications Deploy with FTTN today and add optical splitters to serve new areas tomorrow

o Built-in look-both-ways testing reduces rework and truck rolls by isolating all network segments for testing and troubleshooting in both directions
o Ability to push any service to any subscriber from one location reduces service turn-up time
• Reduce capital expenditures
o Single cross connect location for services delivery ensures no stranded DSLAM ports
o Avoids costly retrofit of legacy cabinets or obtaining right of way by reclaiming up to 50 percent of cabinet space
o Active DSLAM cabinet with integrated service delivery offers cost effective deployment option in a single all-in-one cabinet
• Improve reliability
o Instant visual identification of high value customers avoids disruption of working circuits
o Consistent, secure IDC connections across the outside plant ensure long service life of copper connections
o Logical management of feeder, distribution and jumper cables, and reduced handling of feeder and distribution cable, improves service
