  • 1. Retractable Techniquesin fibre optic infrastructuresAlessandro Pirri – Director Connectivity & FTTx14th February 2012
  • 2. The Installer dream…. FTTH Council Europe – D&O Committee Workshop | 14th Feb 2012 2
  • 3. The basic principle The Stripping Tool has been designed to safely cut the windows on the Riser Step 1 Cable. On a higher floor cut If used properly, it cannot damage the 1st window the selected fibre fibre units. cut: “pick module window” (Typical 20 m) Step 2 On the subscriber’s floor pull back the selected fibre module Optical Line Termination 2nd window cut: “extraction window” FTTH Council Europe – D&O Committee Workshop | 14th Feb 2012 3
  • 4. The basic principle 5 Easy Steps LAY the RetractaCable from Distribution Point along the Homes. 1   LAY   OPEN the RetractaCable in front of the homes to connect. CUT the desired fibre module in the first next (from DP) opened cable spot. 2   OPEN   3   CUT   PULL the cut fibre module out (retract), in case the length is > 50 meter a tool can be used for retracting, storage and pushing or blowing. 4   PULL   5   PUSH/BLOW   PUSH and/or BLOW the retracted fibre module through a drop duct up to the home. FTTH Council Europe – D&O Committee Workshop | 14th Feb 2012 4
  • 5. Specific tools Cutting tools to perform a window cut to access the modules FTTH Council Europe – D&O Committee Workshop | 14th Feb 2012 5
  • 6. Specific tools Picking tool to cut the module inside the cable at 1.5m from the jacket window FTTH Council Europe – D&O Committee Workshop | 14th Feb 2012 6
  • 7. The basic principle Two ways to extract fibre modules •  Cut the fibre module one home further and splice the fibres in the home. •  Cut the fibre module 1.5m from the home and splice the fibres at the tap-off point FTTH Council Europe – D&O Committee Workshop | 14th Feb 2012 7
  • 8. Retractable solutions   Designed for Indoor and OSP   Reduction of 15 to 30% on installation time   Extremely Compact (i.e. 720fo cable with 16mm O.D.)   No cable loop, very small closures, prefab. manholes   Ideal for installation in existing / new duct infrastructures or in soft soil.   The simplicity of the concept reduces the need for skilled labour   Extremely efficient in both brownfield & greenfield sites   G.657A2/B2 fibres FTTH Council Europe – D&O Committee Workshop | 14th Feb 2012 8
