Transcript of "EPON Technology and its Application in China Telecomʹs Access Network Migration"

  1. 1. EPON Technology and its Applicationin China Telecomʹs Access Network Migration Shen Chengbin shencb@sttri.com.cn Shanghai Research Institute of China Telecom April, 2012
  2. 2. Increasing BB subs in China and Technology Evolution 180 45% 160 156 40% 140 35% 126 120 115 30% 103 100 100 25% 83 84 80 20% 66 67 60 52 52 15% 38 37 40 10% 26 20 5% 0 0% 2005 2006 2007 2008 2009 2010 2011 total Subs (DSL+FTTX) ADSL Subs Growth Rate (total) Growth Rate (ADSL) •The immigration from ADSL2+ to FTTx even to FTTH is accelerated •The gap between TOTAL and ADSL in earlier years is Ethernet based FTTB •The gap between TOTAL and ADSL in recent years is PON based FTTX •China broadband subscriber installed base is estimated to reach 180 million ports by 2014 Page 2
  3. 3. Chinas relative lower BB Penetration China BB Household Penetration•Compared with developed coutries, China has lower BBhousehold penetration (<40%) ;•Great development potential and market opportunity! Page 3
  4. 4. CT Broadband Access Subscriber Growth 76.8 63.5 53.5 44.3 35.7 28.4 21.0 14.2 7.4 2.5
  5. 5. China Telecom piloted and promoted EPON/GPON ecosystem in China in 2004, Both IEEE802.3ah and ITU‐T G.984 were released. As a  fixedline operator, China Telecom pays a lot of attention to any  progress in FTTX technologies after a comprehensive evaluation, China Telecom considered EPON  as more mature. e.g. EPON began massive deployments in Japan and  South Korea. in 2005, China Telecom started EPON field trial in 4 provinces to  learn how to deploy EPON EPON Interoperability is critical for the success and deployment of  EPON widely, so China Telecom started IOP research in 2005.  Some technical  issues were solved such as:  MPCP registration Data encryption  ONU authentication:  Report manner & DBA implementation  Logical ID Multicast  MAC based  ONU remote management: using CTC Specific OAM extension (MIB,  alarm, performance) In Q1‐2007 CTC achieved large scale and all‐round chip and system  EPON IOP the first time in the world (3 chip vendors, 10 system  vendors)
  6. 6. CTC Broadband Technology Migration Milestones All these technologies will co- Before 2007, ADSL/ADSL2+  exist in CT access network was the dominant  100M 10G-EPON technology In 2007, CTC and other main  GPON operators started massively  deployment of fiber access  EPON based on ʺFIBER‐IN &  FIBER‐OUTʺ strategy after  50M China Telecom achieved the  all‐around and large‐scale  IOP of EPON  GPON and 10G‐EPON  10M ADSL2+ began deployment after  ADSL EPON 2000 2005 2007 2009 2010 Page 6
  7. 7. EPON is used in variant deployment scenarios in ChinaTelecom  Based on comprehensive analysis on TCO,bandwidth capbility,  technol. Trend, etc., China Telecom adopt different deployment  mode to local conditions: Residential customer, urban  Business buildings, Urban areas areas Green field (new area) Cover all the new business • Stop deploying feeder & •buildings by fiber •FTTO or FTTB distribution copper wires • FTTB (PON) + Ethernet before 2010 Rural areas • FTTH since 2010 Brown field (existing area) Principally stop deploying feeder • (preferred) FTTB (PON)+ copper wires DSL with copper wire length fiber to the village plus DSL < 500m before 2010 •EPON (preferred) • Bandwidth target: 8-20Mb/s •P2P • some residential cell were Bandwidth target: >4Mb/s upgraded by FTTH since 2010
  8. 8. Fiber‐in & Copper‐out historyfrom FTTB/N to FTTH  From 2008 to 2010, through EPON deployment in FTTB/N architecture:1. Customers’ access bandwidth improved significantly2. EPON equipments and ODN technologies were improved, and China Telecom completed OLT distribution in key network points in 2010, PON is mature enough  and ready for FTTH mass  deploymen: •equipment price •engining •technician  •IT system •service process and China Telecom changed to  FTTH leading 8
  9. 9. Chinaʹs EPON Ecosystem ASIC Optics China Telecom has played key role in China EPON ecosysme Page 9
  10. 10. access networks technology and architecture is being changed PON FTTH(PON) Ethernet 1% Ethernet 5% 10% 19% FTTB(PON) 26% DSL DSL 80% 59% 2007 Q1, 2011
  11. 11. CTC announced “Broadband China, Optical City” project  On 16 Feb, 2011, China Telecom announced the majestic project to accelerate  the FTTH deployment – In three years, CTC will complete fiberization of all cities’ BB  networks to achieve the target of 100M to home, 1G to building – by the end of 12th 5‐Years (2015), China Telecom‘s FTTH‐passed  homes will reach 100+ Million marker
  12. 12. FTTx Development Strategy, progress and target Strategy Increase FTTH share in FTTx deployment to provide 20M  for urban residential users and 50~100M for HDTV and/or  multi channel IPTV users starting 2010 Speed up FTTO deployment in commercial buildings  to  provide 100M~1G bandwidth for business users Progress and plan FTTH home pass (new): 2010: 10M; 2011: 30M; 2012: ~25M,  FTTH subscribers (new): 2010: 1M; 2011: 5M; 2012:  maybe>10M FTTB/N home pass (new): 2009: 7M; 2010: 10M; 2011:  10M;2012:maybe >7M Page 12
  13. 13. China Telecom uses EPON as a multiple-play platform EPON is used to bear variant services with low cost in China Telecoms networks Page 13
  14. 14. Development & Application of 10G‐EPON Technol. 2010.11release XG-PON1 standard Commercial chipset and optical TX: Q2,2012 Commercial deployment: end fo 10G 2012 GPON GPON XG-PON1 XG-PON2 Asymmetric Symmetric, no plan Asymmetric & WDM Symmetric PON EPON 10G-EPON IEEE802.3av release in Sep, 2009 Commercial chipset and optical TX will be ok soon Commercial deployment: Q1,2010 2009 2010 2011 2012 China Telecom deeply involved in 10G‐EPON standardization and industry  improvement. in Apr. 2011, CTC achieved 10G‐EPON interoperability 10G‐EPON or XG‐PON1 will be deployed first to improve MDU’s uplink  bandwidth to achieve FTTH‐like capacity for each subscriber More than 500 ports 10G‐EPON fed MDU are already in operation in China  Telecom networks
  15. 15. China Telecom actively take part in PONstandardization  China Telecom deeply involved in IEEE802.3av and IEEE1904.1  China Telecom promoted EPON in BBF together partners – TR‐200: Using EPON in the context of TR‐101 – WT‐287: Optical Layer Management  China Telecom contributes also to FSAN and ITU‐T to GPON  standards, and some key contributions were adopted  China Telecom pushes China PON industry in CCSA (China  Communication Standardizaiton Association) to promote China  Telecomʹs specs to be a Chinese industry standards – EPON interoperability – 10G‐EPON – TDM over EPON and GPON Page 15
  16. 16. BTW: China Telecom’s View on GPON Now, GPON technology and equipment are mature  enough to meet China Telecom FTTH deployment  requirements Massive GPON deployment in FTTH kicked off from  2010 with volume increasing dramatically CT will migrate FTTB/N into 10G PON in future (10G  EPON first) as both GPON and EPON do not provide  sufficient bandwidth to meet growing customer  demandGPON and EPON will co-exist for FTTH deployment in the next few years.
