  9. BELGACOM’s NETWORKARCHITECTURES EVOLUTION DISTRIBUTION F.O. : ALTERNATIVE Pulling Fibre System (PFS) MAINETTIE : ducts RAYCHEM : splices, ... OPTICAL FIBRE : fibres MICROLIGHT - S.A. VULCAN Pilot projects in 1996 Fine tuning of the system : 02/97 Commercial projects : 1Q98 Volume Deployment : 3Q98 DUCTS ! * no more splice holes * cheaper splicing technology = copper * installation of the fibres when there is a new customer ==> ROI 

  10. 2. Modular Cabling Systems Technical Evaluation

  11. Modular cabling systemsTechnical evaluation • product description • manufacturers • competing technologies • network concept • field trial(s)

  12. Modular cabling systemsproduct description • multi- tube system : 2/4/7/19-way • direct buried version • direct installed version • multi-fibre units : 2/4/8 fibre units • installation techniques : • blown fibre technique • pulled fibre technique • mechanical building blocks : • tube branchout and connecting joints • repair kit • customer lead in box

  13. Competing technologies • “traditional” fibre optic cabling technology : • 4 or 8 fibres per tube • FIST technology for customer independence • usage of concrete manholes for splicing and/or recoiling ; no direct buried splices • “inline” fibre optic cabling technology : • idem + direct buried customer connection splice • “modular cabling” technology • 2,4 or 8 fibre unit per tube • only one splice at Optical Node • whole system is direct buried • handling of the system : similar as copper outside plant

  14. Modular system Network Concept Advantagesof a modular fibre system : • low up front investment • modular, adaptable upon demand from outside to inside • rapid fibre deployment • no overkill investments • point to point fibre reduces # of splices • installation of fibre bundles on demand Disadvantages of a modular fibre system : • installation of individual fibre bundles more time consuming • more complex repair

  15. Modular system Network view • ideally suited as distribution and drop system for direct connection of customers

  16. Modular system Network view • optional for FTT/C-KVD (from ON to KVD) in a non-full deployment strategy

  17. Modular system Network Concepttowards implementation • simplicity of the system assures the retrainability of “copper people” due to similarity in handling with the existing copper technology

  19. FTT BUILDING PILOT PROJECT IN NIEUWPOORT Introduction : - connect new buildings in F.O. - connect existing buildings in F.O. Desaturates KVD’s so that growth of uni-familial houses and small buildings can be handled by existing KVD’s/cu-network. • Introduction of the site : • Fundamental plan of the network Nieuwpoort • Topographical plan of the site
