FTTH Conference 2011 Workshop FTTH Deployment Techniques Colin Kirkpatrick EMTELLE

  1. 1. 2011FTTH Deployment Techniques In Existing Infrastructure
  2. 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. 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. 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. 5. Deployment Methods In Existing InfrastructureUnder ground Ducts and Subducts Sewers & WaterwaysOverhead
  6. 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. 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. 8. New Sub-ducting Trend (Part Filled)110mm duct with 24 x 14/10 tube66% Duct Fill
  9. 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. 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. 11. Aerial Installation Overhead – Rural and Urban
  12. 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. 13. Alternative Lower Cost Deployment Techniques New BuildMicrotrenching Microtrenching Mole Ploughing(150mm width) (20mm width)
  14. 14. Slot CuttingDifferent sizemachines canprovide various cutsizes
  15. 15. DBfmf (direct buried filled metal free)from 3DBfmf up to 7DBfmf 12/10mm
  16. 16. Stages of Cleanfast processGPR Detection Trenching Refilling with a Duct-laying specific mortar Final reinstatement
  17. 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. 18. Blown Fibre Supply Options Sub-Divisioning of Existing New Build Ducted Networks Direct Bury OrDirect Install Products SubDucting
  19. 19. Mole Plough / Trenching
  20. 20. New or Existing Build
  21. 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.
