ADC has leveraged its recognized expertise in developing quality fiber infrastructure solutions for the central office and has brought that expertise to the outside plant environment, with our FDTs. ADC’s FDTs have the capability to serve up to 1,152 homes and enable high OLT efficiency, and physical layer access to fibers within the feeder and distribution network. Internal FDT Diagram Our FDT’s incorporate four time-tested elements that have long impacted reliability, flexibility and operational costs within the central office environment: • Bend radius protection - Fibers bent beyond the specified minimum bend diameters can fracture, causing service failures and increasing network operations costs. Adding new fibers can easily bend the bottom fiber beyond its minimum bend radius and suddenly cause an increased level of attenuation and a shorter service life. By emphasizing fiber cable management, ADC provides bend radius protection at all points where a fiber cable is making a bend. This practice increases long-term reliability of FTTP End-to-End Fiber Infrastructure 1/24/2006 FTTP Fiber Infrastructure Pg 3 of 20 the network, reduces network down time, and ultimately reduces the operational cost of the network. • Intuitive cable routing – ADC’s cable routing provides a very clear path for the technician to route particular cable, leaving fewer options and virtually eliminating the chance for human error. In addition, having defined routing paths makes accessing individual fibers much easier, quicker and safer, thus reducing the time required for reconfigurations. Intuitive cable routing paths also reduce the training time required for technicians and make patch cord routing and rerouting a simpler operation. • Easy fiber/connector access – ADC’s FDT provides the ability to store unmated connector pairs in a “parking lot”. This parking lot is a key factor in maintaining connector cleanliness. Each connector sent with the cabinet, or in our splitter packages, will have a dust cap installed just after final testing, cleaning and end-face inspection. These clean connectors are then placed in 8-pack “parking lots” for simple installation in the cabinet. Additionally, ADC places individually accessible connector adapters on the front of each panel in the FDT. The recommended practice of scoping every fiber connector, as it is cleaned, can be both cumbersome and expensive. This is alleviated with the simple and quick access ability to each connector adapter. Technicians have much easier access for cleaning and turn-up operations, thus ensuring best optical performance. Superior fiber cable accessibility also ensures that any fiber can be installed or removed without inducing a macrobend or otherwise damaging an adjacent fiber. • Physical protection – Physically protecting every fiber and connector from inadvertent damage is a major concern in cable management. ADC’s cabinet design ensures maximum protection for every optical cable and component. Fibers that are routed between pieces of equipment without proper protection are very susceptible to damage. ADC’s fiber cable management system ensures the physical protection of every fiber and component.

All components (Central Office Fiber Distribution Frames, OSP Fiber Distribution Terminal, OSP Fiber Access Terminal and Drop Cables) of ADC ’s Fiber-to-the-Premise fiber infrastructure utilize fiber optic connectors, which make them a very important component in the end-to-end solution. ADC Ultra Polished SC and Angle Polished SC connectors have been tested and comply with GR-326 Optical Connector Performance specifications. This ensures CUSTOMER NAME is receiving reliable and quality connectors. To ensure our quality and reliability, ADC test 100% of its connectors, which includes a visual inspection, optical data (insertion loss/return loss) and endface geometry (apex offset, fiber recession and radius of curvature). As Telefonica outlines it’s plan for FTTP, it is important to consider the FTTP architecture differently than the traditional copper environment because of the fresh, new network, high bandwidth services riding glass and differences in plant characteristics. Furthermore, it is also just as important to understand the key advantages that the copper network has afforded carriers for many years and these same network architectural principles in designing a profitable FTTP network. The cost of network operation and the ability to provide high bandwidth services extend far beyond the equipment and installation expenditures. Through our experience, we have found that Carriers across the country do not underestimate the need for fiber access in a FTTP network operation. Through connectorization, fiber access provides carriers with: • Faster turn-up of high revenue generating services • Ability to more efficiently test, troubleshoot and isolate network problems • Quick and easy reconfiguration • Simplified training for technicians • Reduced labor costs during network implementation and future network maintenance In our world of high revenue-generating services, it is important that Telefonica customers experience minimal down time in troubleshooting isolation. ADC has completed a number of studies that show the costs associated with service outages as outlined in this proposal. It is clear that without fiber connector access for troubleshooting, end-customers can experiences outages in days rather than hours. Fiber Connectorization FTTP End-to-End Fiber Infrastructure 1/24/2006 FTTP Fiber Infrastructure Pg 5 of 20 Factory connectorization minimizes installation expenses and maximizes network performance by eliminating additional labor costs and termination gaffes in the field. ADC understands the complexities of its panels and the optimal methods for termination. Pre-connectorized panels and cables are terminated correctly the first time, eliminating "do-it-again" costs. Reliability, flexibility and quality – deployed faster and less expensive. The merits of factory connectorization have never been clearer. By incorporating vertically integrated manufacturing processes, ADC can expedite delivery of customized terminated panels at lower costs, with one catalog number, from one source. Vertical integration enables Telefonica to custom-tailor terminated panels, splitters and cables to suit the unique requirements of specific applications. And because ADC controls every step in the manufacturing process, we can ensure you receive the right products, at the right time. ADC pre-connectorization process offers several additional advantages: • All connectors are polished and terminated in a clean environment and inspected by a quality control program • Test results are documented and provided with each assembly • All expendables, labor and "do-it-again" costs are incurred by ADC FTTP End-to-End Fiber Infrastructure 1/24/2006 FTTP Fiber Infrastructure Pg 6 of 20 Fiber Access Terminals Fiber Access Terminal/Pedestal Overview ADC Fiber Access Terminals provide a robust, user friendly, and cost effective platform for delivering fiber optic drops in FTTP deployments, for both single- family homes as well as for multi dwelling units. ADC Fiber Access Terminals provide physical protection, long-life reliability, superior fiber management and an aesthetically appealing appearance. ADC pedestal offering adds two critical differentiators from that of our competitor’s pedestals; splicing capabilities and slack storage within the pedestal. With the ability to splice and store fibers within the pedestal, it eliminates the need for a separate enclosure and/or handhole, thus saving on initial capital expenditures. In addition, ADC pedestal offering provides Telefonica with increased operational efficiencies by allowing easy access to splices and decreased restoration time. The dome-style pedestals provide a continuous barrier to water and rodent intrusion, and use the bell-jar effect to provide flood protection up to NEMA 6 standards. To achieve long-term flexibility and reliability, the fiber management inside our Access Terminals ensure proper bend radius.

ADC splitter modules are designed to be protected from exposure and damage by their packaging. Telefonica can rest assure when implementing ADC splitters into the outside plant, that you will receive high-quality and reliable splitters. Our splitter modules are GR-1209 (Splitter Service Life) and GR-1221 (Splitter Reliability) tested and uses GR-326 test connectors. ADC splitter modules are surrounded by superior cable management. Technicians need less time to route fiber in the cabinet, thus allowing Telefonica to realize operational cost savings. Splitter modules are available in configurations from 1x4 up to 1x32, the modules can be ordered in adapter port or pigtailed versions. Centralized vs. Cascade Splitter Configurations There are two common splitter configurations, centralized and cascade configurations. The centralized splitter approach typically uses a 1x32 splitter in an outside plant enclosure, such as a fiber distribution terminal (FDT). In the case of a 1 x 32 splitter, each device is connected to an optical line terminal (OLT) in the central office. The 32 split fibers are routed directly from the optical splitter through the distribution panels, splice points and/or access connectors, to the optical network terminals (ONT) at 32 homes. The cascade splitter approach is normally with a 1x4 splitter residing in the OSP enclosure and connected directly to an OLT in the central office. Each of the four fibers leaving the 1x4 splitter is routed to an access terminal housing, either a 1x4 or 1x8. Optimally, there would eventually be 32 fibers reaching the ONTs of 32 homes.
