Breakout session day 2 fiber for everyone helmut schink

  1. 1. Economic Deployment of Optical Access Infrastructure Based on Standards Helmut Schink, VC of ITU-T SG 15 helmut.schink@nsn.com Committed to Connecting the World
  2. 2. OECD:Broadband is a General purpose technology
  3. 3. OECD: Private investment decisions Governments increasingly Uncaptured step in to cover the difference social benefits (spillovers) Private expected PrivatePrivate Private return rolloutrollout expected cost cost return Yes No (but should socially)
  4. 4. OECD: Fibre deployment and standards Facilitates deployment • Common protocols, specifications • Avoid the risk of fragmented solutions, “de facto” standards • Guarantee interoperability • Stimulate competition • Some examples: cables, fibres, connectors, passive elements, etc. Impact on competition o Connectors:  Interconnection devices/operators,  Multiple fibres, allowing switching, etc. o Passive elements  Wholesale access to passive infrastructures

  7. 7. Unbundling options Unbundling Options P2P G-PON WDM-PON Coherent PON XG-PON Duct sharing Valid option, however economically challenging & regulation may apply Spectrum sharing without segregation filters Layer 1 unbundling type: option for unbundling at OLT level Spectrum sharing with segregation filters Layer 1 unbundling type: less flexible Bitstream unbundling in OLT Layer 2 unbundling type: frequently regulator requires unbundling at OLT site, incumbents may prefer this option, but gives competitors no direct access to the PON PPP/L2TP based Bitstream unbundling in IP Edge Layer 2 unbundling type: Solution of today, works only for best effort

  11. 11. Optical cables miniaturization trend The reduction of diameter and weight of the mini cables allow the installation in very small ducts with innovative techniques as air blowing. The same products can be installed in overhead plants or on building facades.Traditional cable Mini cable 96 o.f.  Up to 120 (144) o.f. Diameter 15 mm  Diameter 8 mm Weight 200 Kg/Km  Weight 50 Kg/Km Bending Radius 210 mm  Bending Radius 160 mm Winch installatiion  Air blowing installation 11
  12. 12. Infrastructure miniaturization trend• In the same way also the dimensions of ducts can be reduced.• In this new scenario large dimension road cuttings are unnecessary, as sections of several cm or some tens cm are sufficient. TRADITIONAL MINIATURIZED Diameter 10/14 mm (inner/outer) Outer Diameter 40 or 50 mm 12
