  1. Joint ITU/IEEE Workshop on Ethernet - Emerging Applications and Technologies(Geneva, Switzerland, 22 September2012) FTTH in Portugal- Past, Present and the Future Paulo Mão-Cheia, Portugal Telecom maocheia@telecom.pt

  2. Agenda • Portugal Telecom – Global Operator • Why FTTH is needed - Portugal Telecom use case • FTTH in Portugal • The Future of FTTH • Conclusions

  3. Portugal Telecom Global Operator PT has placed Portugal in the forefront of innovative telecom solutions

  4. Portugal Telecom Global Operator Reinforce competitive position Efficiency and cash-low Growth scale Focused strategy based on 3 key markets: Portugal, Brazil and Africa Innovation as a critical success factor

  5. Agenda • Portugal Telecom – Global Operator • Why FTTH is needed - Portugal Telecom use case • FTTH in Portugal • The Future of FTTH • Conclusions

  6. Why FTTH is neededPortugal Telecom use case • Exponential demand for bandwidth and integrated 3P services requires a future-proof network evolution path • New services require increased bandwidth … that only FTTH will provide in long term Speed Kbps Mbps Gbps 10 100 1 10 20 50 100 400 1 4 10 40 Fibre NGPON B-PON G-PON E-PON Cable DOCSIS 2.0 DOCSIS 3.0 Copper PSTN MDSL ADSL ADSL2+ VDSL

  7. Why FTTH is neededPortugal Telecom use case + speed + efficiency EP2P (optical fibre) GPON (optical fibre) xDSL (legacy) CPE ONT ONT DSLAM PD CPE OLT Splitter ONT OLT ONT CPE ONT ONT • Lower CAPEX with reductions of 30% to 60% • Less OPEX with reduced energy consumption (~2,5 time less) • Less space required, with equipment ~7 times more concentrated • Potential to increase bandwidth with lower split ration (and in the medium term, with NGPON) • Lower OPEX with reduced energy consumption (4 to 5 times less) • Less space required, with equipment 4 to 6 times more concentrated • Better quality of service with loss down time

  8. Why FTTH is neededPortugal Telecom use case Residential (IPTV, HSI, VoIP) Corporate/Soho (Different Services Classes) Mobile Backhaul (UMTS, LTE) FTTH network supports the aggregation of different traffic types:

  9. Why FTTH is neededPortugal Telecom use case 3 Constant High Speed Internet via wireless 2 Home Gateway • Premium Channels provided only over STB STB IP ETHERNET STB ONT Web Access Network Domestic network 1 Simplified installation by reuse Coax home network Coax … RF Maximum quality of service: stable and strong 4

  10. Agenda • Portugal Telecom – Global Operator • Why FTTH is needed - Portugal Telecom use case • FTTH in Portugal • The Future of FTTH • Conclusions

  11. FTTH in Portugal • 2.5 Gbps downstream • 1.25 Gbps upstream • B+ class GPON (28dB) In the PT case, each PON, in a B+ class GPON, supports 64 ONTs that are acquired by the use of two or three levels of splitting . Typical distance <20km. RF Overlay carries up 70 PAL B/G TV channels

  12. FTTH in Portugal Typical<20 km ONT HUB HE LOCAL HE Remote Head End ONT ONT OLT ONT WDM central office & ONU characteristics: G.984.5 • RF Overlay network designed to maximize use of remote Head End • ODN Network uses two or three(2x2@CO) stage splitting

  13. Agenda • Portugal Telecom – Global Operator • Why FTTH is needed - Portugal Telecom use case • FTTH in Portugal • The Future of FTTH • Conclusions

  14. The Future of FTTH ONU CO ONU NG-PON2 OLT NGONU [nm] [nm] WDM Filter 1490 NGONU GPON OLT ONU 1310 1555 RF VIDEO 1270 XG-ONU Monitoring 1650 • NG-PON2 Requirement for coexistence with RF Overlay in GPON scenario: • Support of RF Overlay is needed; • Minimize impact on the RF performance; • Upgrade to NG-PON with minimal service disruption of GPON clients; • Increase the bandwidth to ≥10 Gb/s DS & US, ie NG-PON2

  15. Conclusions and Recommendations • FTTH provided PT an opportunity to grow in terms of revenues and regaining clients • NG-PON2 standards are critical to allow network growth over existing ODN, to target new business services
