Fiber Distribution Terminal (FDT)
FDT Overview
One of the key components of an FTTP network is the Fiber Distribution Terminal (FDT) where all of the fiber from the central office is split and distributed to the end users 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

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
FDT Features and Benefits
Removable retainers Allow cleaning of single connector without disturbing adjacent circuits Integrated slack storage spools Allow storage of excess fiber while providing
positive 1.5" bend radius control
Angled bulkhead panel Provides easy hand access to connectors and prevents 90 degree bends on connector boots Small size Minimal protrusion from ground (less than 48 inches) help with right-of-way concerns Condensation foam and
Detailed routing information
Information at point of use assures accurate and consistent cable routing, and speeds service turn-up or routine maintenance
All splitter connectors are preloaded
into parking lot Allows for dust cap to remain on connector from factory, limiting field cleaning time

Connector and Fiber Connectorization Overview
ADC fiber optic connectors can help Telefonica minimize operational expenses and maximize network performance 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

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

Splitter Modules
Splitter Module Overview
ADC splitter modules are installed in our Fiber Distribution Terminals and give Telefonica the ability to split signals to multiple homes and businesses 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
