  1. P614 TASK 5FTTH What future for FTTH?

  2. Three key conditions for short/medium term FTTH implementation: Powering, Network quality, Service strategy Swisscom, CSELT, DTAG, Hungarian Telecom, Telenor Eric Demierre, Swisscom Philippe Schroeter, Swisscom

  3. New environment & opportunities for FTTH The approach of P614 Task 5 Achieved results by P614 Task 5 Powering Availability Example of investment costs Conclusions P614 Task 5: Content of presentation

  4. Engagement of several PNOs in FTTH (=> large scale production) Penetration of GSM and mobile services (=> role of the fixed access network is changing) Importance of investments for PNOs (=> flexible, future proof connected with revenues) Demand for low-cost high bandwidth access (=> multimedia, Internet, ...) New environment & opportunities for FTTH

  5. Growth of the Internet telephony (=> voice can be transported on data networks) Lower availability of services (=> PCs are out of order during power mains failure) Low availability of applications (=> Software incompatibility problems, bugs in the operating systems) Need of service symmetry (=> e.g. teleworking) New environment & opportunities for FTTH

  6. Hypotheses: FTTH is complementary to GSM The approach of P614 Task 5

  7. Powering for FTTH: architectures, availability, costs (Deliverable 12) Availability models for FTTH with costs (Deliverable 13) Characteristics of BB services taking into account FTTH (Deliverable 14) Elaboration of common FTTH guidelines (Deliverable 8) Achieved results by P614 Task 5

  8. Powering:Unavailability & Back-up

  9. Preferred Powering Solution for FTTH:Local Powering • Local powering by means of an AC/DC converter. • ONU power consumption from 6.5 W to 13 W • Optional back-up example: • 6.5 W minimum (core 5 W + telephony card 1.5 W) • Ni-Cd battery Panasonic P-V215A (6V, C2.5=1200 mAh), cost 70$ • Additional cost for battery charger and regulator, 10$ to 20$ • Total additional cost 80$ to 90$

  10. FTTH APON element Mean time Unavailability Down time per to repair [h] year -4 3.5 53min OLT equipment 1.0·10 OLT power supply neglect neglect Fibre (feeder and distribution, 2km) 21 2·10 10min -5 Optical splitter 2·10 -6 1min 21 -4 ONU equipment 2.4·10 24 2h 07min -4 ONU power supply, local powering, no back-up 2.7·10 2h 23min -4 6.3 10 5h 33min Total FTTH APON Availability Unavailability and down time per year for FTTH APON (low cost implementation) Increase of availability: • Enhancement of ONU power supply availability using power back-up • Enhancement of OLT and/or ONU equipment availability

  11. Availability: Contribution of elements

  12. Hypothesis All 512 ONUs are installed and connected to one OLT Average distances: OLT - splitter: 1.6 km, splitter - ONU: 400 m One fibre per O/E (to save splitter and splicing costs) Investment costs of the whole PON: mk = number of elements Pk = unit price per element Analysis of Investment Costs

  13. ATM-PON: Analysis of Investment Costs

  14. Greenfield situations Old copper network needs to be replaced Provisioning of digital video (similar to CATV) Situations where installation of aerial cables is possible. Spare room in ducts Existing tube for air blow fibre Promising Situations for Short-Term FTTH

  15. A low-cost FTTH solution is proposed as a suitable solution for matching customer wishes and operator requirements. The solution has been justified in term of services, availability, powering and costs. Technical issues and justifications have been made available in 4 deliverables (Deliverable 12, 23, 14 and 8) Conclusion
