With the ODN driving down construction costs and boosting ROI, FTTx is powering along a rapid development path. The

iODN is the culmination of the industrys strong focus on building, operating and maintaining the ODN cost-effectively.

The iODN, a smart fiber manager

ODN management is vital

tatistics reveal that 150 millionFx subscriber lines weredeployed worldwide in 2009.

Over the next three years, upto 800 million Fx subscriber linesare expected to be added, heralding anFx boom. In China, the year 2009saw the deployment o 20 million Fxports and 55 million kilometers o fbercore, relecting a 20% annual growthrate in the fber area.

o ride the Fx boom, the accesslayer must come equipped with a hugeoptical distribution network (ODN).ODN construction does not come

cheap, however, accounting or up to 50-70% o total FH investment. Giventhe ever-increasing bandwidth demandby services, the ODN must be able tosustain long-term broadband networkdevelopment regardless o the technologyand the liecycle o major equipment.

he ODN also represents the mostdiicult part o Fx management, asit is undamentally more complex thana copper wire network. Te latter existsthrough a simple P2P structure, unlike

the ODNs predominant P2MP topologythat requires multiple connecting nodesand a solution or complex networkmanagement. In addition, ibers aremore vulnerable to operational errors andattacks by rodents.

Eicient ODN construction andO&M necessitate a set o intelligentand accurate management solutions thatully utilize the ODN and eectivelyp r o t e c t l o n g - t e r m i n v e s t m e n t .Consequently, leading operators and

S

standardization organizations such asthe IU- are beginning to prioritizeeasible ODN management.

iODN: an ideal

management toolODN management is simple and

basic in the context o a PON. heinventory management system storesdata about copper wires, ibers, pipes,and distribution rames, which is thenretrieved during service activation andmaintenance. However, this managementmodel creates two major problems.

First, manual data entry is plaguedby an average error rate o 20%. During

construction, engineers must printengineering drawings and perorm tasksby deault rules, such as numbering boardports rom let to right and manuallyentering all network inormation intoa database. Human error compromisesthis process, and database inormationquickly becomes out o date due toimproper management.

Second, manual operations induceinecient O&M. At the O&M phase,all fbers in a PON are located manually,

which lowers network managementeiciency and dampens broadbandservice growth.

So, can ODN management beautomated to solve these problems? WithHuaweis intelligent ODN (iODN)solution, the answer is a decisive yes.Te solution adds a number o intelligentcapabilities to the network withoutchanging any passive ODN eatures.Incorporating a PDA with visualizationsotware to simpliy and enhance ield

operations, the solution provides suchintelligent capabilities as fber connectionidentifcation and management, intelligentfber indicators, intelligent optical splittermanagement, port searches, and thecollation o port status data. he PDA

enables the ODN to communicate withthe inventory management system inreal time through a wireless MAN or a

wired broadband network, while the PDAconnects with, and can temporarily power,the iODN through a USB port.

Fiber ID management: Embeddedwith an eID, the iber connector readsthe eID data o plug-in ibers to realizeintelligent fber management. Similar to anMAC address, the eID provides a globallyunique identifer that stores data o a given

fber, including its route, position in theoptical cable sequence, and connectedoptical splitter or distribution module. Bymanaging the eID, the solution controlsfber links across the ODN by such meansas automatically generating a topology andchecking the fber connections.

Port status collection:An iODNdevice can automatically collect and reportthe resource status by reading and thendownloading the fber connection status oall ports to the PDA through a USB port.

Port search indication:Activated bythe management module, each port inan iODN device uses an LED indicatorto display the iber port that requiresmaintenance. his raises the precisionand ease o onsite maintenance via avisual interace.

Visualized PDA: Te PDA providesthree unctions. First, it suppliestemporary power via a USB portconnection and activates the managementmodule o the iODN. Second, it serves

Huawei Communicate

as a communication bridge between theiODN and the inventory management

system to enable data exchange. Tird, asthe major construction and maintenanceinterace, it acilitates dispatch listmanagement, operational instructions,and inormation inquiries. Each unctionis accompanied by a graphical interace,

which greatly improves O&M eciency,ease and accuracy or engineers.

Unprecedented easeof use

Intelligent and automated, the HuaweiiODN solution represents the optimum

method or easing the challenges oconstruction and O&M, reducing costs,and maximizing eciency.

he solution allows engineers to reelydownload electronic drawings on a PDAthrough wireless or fxed networks, ratherthan completing them during construction.he PDA and the iODN connect via aUSB connector, so engineers are no longerrequired to memorize a series o deaultrules. Construction tasks can be accuratelyand eiciently completed by ollowing

the LED indicators and the PDA. Insteado completing a conirmation orm onproject completion, engineers can use thePDA to collate connections and port statusdata, which the PDA then uploads to the

inventory management system.When the PDA has obtained electronic

dispatch lists during routine maintenance,engineers can simply insert the PDA intothe iODN, and the LED indicator andthe PDA display will immediately indicatei a port requires maintenance, helpingthem perorm O&M tasks accurately. TePDA also automatically records changesto the data about iber links, ports andothers and reports them to the inventorymanagement system to synchronize

system data.Tus, the iODN solution automatically

records and manages ODN iberconnection inormation to maintain theaccuracy and timeliness o the inventorymanagement system and eliminatehuman error. In addition, the visualizationsotware on the PDA and the smart LEDindications on the iODN combine tosupport automatic fber search and accurateoperations, signifcantly improving O&Meciency.

Based on the iODN structure, theinventory management system supportsa variety o value-added applications orautomated construction and O&M. Forinstance, the system can automaticallygenerate the tools and materials requiredor a dispatch list and create an onlinematerial request worklow. With itsbuilt-in GPS, the iODN and PDAcan automatically navigate engineersto ODN sites without the need orinormation analysis.

As a smart fber network manager, theiODN solution inuses the end-to-endODN construction and maintenanceprocess with cutting-edge electronics,intelligence, and automation capabilitiesthat vastly improve O&M eciency andprotect ODN investment.
