  • 1. 2011FTTH Deployment Techniques In Existing Infrastructure
  • 2. MDU – Do It Right First Time Background To Emtelle• One of the Leading suppliers of Blown Fibre passive network infrastructure solutions with its Fibreflow microducting system• UK - uPVC Primary Duct (1981)• Europe - HDPE Duct / Sub Duct (1994)• Rope in Duct / Cable in Duct (1998)• Blown Fibre Tube Bundles (1993)• Installation Equipment / Training (1997)• Fibre Mini Bundles and Mini Cables (2005 onwards) Emtelle: innovation is our tradition
  • 3. Development of Duct Solutions Trends / Drivers:– Evolution of Cable design (getting smaller)– Future Proofing– Development of deployment techniques– Use of existing Ducted Infrastructure– Use of Existing Overhead Infrastructure
  • 4. Cable Evolution 96 fibre 2000 12 fibres per tube 96 fibre 13mm OD8 fibre Blow / Pulled1980s 96 fibre 20081 fibre per tube 1990s 12 fibres per tube10mm OD - pulled 7mm OD 8 fibres per tube Blowable 18mm OD - pulled 2011 144 fibre 24 fibres per tube 7.9mm OD Blowable
  • 5. Deployment Methods In Existing InfrastructureUnder ground Ducts and Subducts Sewers & WaterwaysOverhead
  • 6. Current Sub-ducting Trend into Existing Ducts110mm duct with 4 x 35/30 subducts into a 100mm ductor 40/50mm Direct Buried Subducts
  • 7. New Sub-ducting Trend (Day 1)110mm duct with 7 x 14/10 tubes Benefit to Telco’s :- • Cheaper ducts •Takes up less room •Faster cable installation Benefit to Operator & Constructor :- • Smaller products, so easier and faster to install •Less machinery required • Tubes take up less room, so more opportunities for ‘Over Ducting’ • Smaller tubes are more forgiving when installing around bends etc,
  • 8. New Sub-ducting Trend (Part Filled)110mm duct with 24 x 14/10 tube66% Duct Fill
  • 9. Duct Install4x 14/10mm primary tube All primary tubes can be pulled ininstalled into 63mm Sub at the same time, using 4 smallduct pull socks attached to a larger main pull sock
  • 10. Water, Waste and Tunnel SystemsSewers, Culverts & Tunnels - Pro’s• Most commonly used in Cities as an alternative to Trenching or poles• Quick cable installation• Reduced damage risk• Long installation lengths achievableSewers, Culverts & Tunnels - Con’s• Politics• Cables to be rodent resistant• Trenches required to link to existing networks and new customers• Co-operation required from other utilities
  • 11. Aerial Installation Overhead – Rural and Urban
  • 12. Over Head Solutions • Use of Existing Poles from other Operators • A charge may be made each time a cable is installed on a pole. • With Emtelle Blown Fibre, Only 1 Cable is installed on a pole.Large 14mm tube for 96 or 144 24 x 4mm tubes for drops to homes 12 x 4mm tubes and a centralfibre cable and central 8mm tube for 12 fibres 14mm tube for main fibre cable (For PON) runs
  • 13. Alternative Lower Cost Deployment Techniques New BuildMicrotrenching Microtrenching Mole Ploughing(150mm width) (20mm width)
  • 14. Slot CuttingDifferent sizemachines canprovide various cutsizes
  • 15. DBfmf (direct buried filled metal free)from 3DBfmf up to 7DBfmf 12/10mm
  • 16. Stages of Cleanfast processGPR Detection Trenching Refilling with a Duct-laying specific mortar Final reinstatement
  • 17. Slot CuttingSlot Cutting• Niche application in certain areas – Very cost effective – Low environmental impact compared with open cut methods – Shallow depth limitation of 220-250mm – Fibre provision is enough for small business applications – Can be incorporated into existing underground Infrastructure – Risk of future damage due to shallow burial depth
  • 18. Blown Fibre Supply Options Sub-Divisioning of Existing New Build Ducted Networks Direct Bury OrDirect Install Products SubDucting
  • 19. Mole Plough / Trenching
  • 20. New or Existing Build
  • 21. How Far can you blow fibre in One point to point blow ? • 4 fibre - upto 1500m max in typical route • 500m in this route (up and down 4 times) (average installation speed was 49m/min) • 8 & 12 fibre 800 – 1000m • 72 fibre cable in 10/8 tube, 1000-1500m • 72 fibre cable in 12/9.4mm tube 2.2km • 96 fibre cable in 12/9.4mm tube 1000m The above distances are point to point blows. Fibre can be centre blown and onward blown to get 6km splice-less fibre lengths.
