  1. 1. Challenges in open access gateway design Kees de Waard, Director of Business Development, Genexis Open Access Workshop, FTTH Conference 2013, London (UK)

  3. 3. Access Bandwidth Per User – 30Y Trend 10  Gbps     1  Gbps   Twisted pair Cable Fiber Growth trends ~50% annual increase 2015            2019            2023   Based on: © Genexis BV | all rights reserved
  4. 4. Fiber To The Home – Three Layers Exist Layer  3:  Service  layer   L3:  Service  layer   •  Determines  end-­‐user  experience   •  Should-­‐be:  self-­‐installable,  powerful   Layer  2:  Transport  layer   L2:  Transport  layer   •  Increasing  amount  of  choices  to  deal  with   •  Should  be:  cost-­‐effecHve  under  growth   Layer  1:  Passive  layer   L1:  Passive  layer   •  Highest  iniHal  investment   •  Should  be:  Layer  2-­‐agnosHc,  future  proof  4 © Genexis BV | all rights reserved
  5. 5. Open Access Network Business Models L3   =       L2   =       L1     = •  Open Access FTTH has different operators at each layer, namely: •  Passive Infrastructure Provider, e.g. Reggefiber, Stokab •  Network or Connection Provider, e.g. KPN-ITNS, Accione, GITpa, DST •  Service Provider, e.g. KPN, Tele2, Adamo, Orange5 [M.  ForzaH,  ACREO,  ICTON  2010  conference,  Jun.  2010,  Munich  (DE)]   © Genexis BV | all rights reserved
  6. 6. Matching The Gateway to Open Access Layer  3:  Service  layer   •  FTTH  CPE:  ResidenHal  Gateway   L3:  Service  layer   •  Service  Provider   •  Lifecycle:  2-­‐5  years   Layer  2:  Transport  layer   •  FTTH  CPE:  OpHcal  Network  TerminaHon   L2:  Transport  layer   •  Network/ConnecHon  Provider   •  Lifecycle:  8-­‐10  years   Layer  1:  Passive  layer   •  FTTH  CPE:  Fiber  TerminaHon  Unit   L1:  Passive  layer   •  Passive  Infrastructure  Provider   •  Lifecycle  :  >20  years   •  An FTTH gateway solution consists of 3 modules: FTU, ONT, and RG •  What are some of the challenges in open access?6 © Genexis BV | all rights reserved
  7. 7. L1: Fiber termination unit External  patch  cord                            Internal  fiber  splice   •  The fiber termination unit (FTU) is the passive demarcation point •  Desktop placement of ONT using an optical patch cord •  Wall-mount “click-on” installation using fiber-splice solution •  Challenge: diversity of solutions in shape, size, and interface •  Also, fiber regulation is different per country7 © Genexis BV | all rights reserved
  8. 8. L2: Optical network termination External  wiring  to  RG              “click-­‐on”  RG  installaHon   •  Optical network termination (ONT) is the network demarcation point •  External residential gateway is remotely located or “click-on” •  Any transport layer is terminated: GPON, Ethernet PTP, WDM PON, … •  Challenge: How to separate responsibilities between NP and SP when ONT is integrated with RG? 8 © Genexis BV | all rights reserved
  9. 9. L3: Residential Gateway “One-­‐box”  with  ONT                                              “Click-­‐on”                                                                  Desktop   •  The residential gateway (RG) is the service demarcation point •  A “one-box” solution: Integrated with the ONT, trending in USA •  A “click-on” module: Flexible service platform independent of the ONT •  Desktop gateway using patch cords •  Challenge: How to manage open access and diversity of bandwidth provisioning inside the home? 9 © Genexis BV | all rights reserved
  10. 10. Example: Integrated FTTH Gateway L2:  Transport  layer   L3:  Service  layer   FTU                                                                                                                    ONT                                                                                                                  RG   •  The individual modules allow heterogeneity and facilitate change •  Each module can have a different owner with separated responsibility •  Modules can be changed independently of one and other •  Is this this open access gateway?10 © Genexis BV | all rights reserved
  11. 11. Management and Provisioning Element  manager   TR-­‐069   SNMP   SNMP   OMCi   CLI   DHCP/TFTP   •  The ONT and RG are managed separately •  The ONT transports the data that is terminated at the RG •  Such separation of functionalities follows BBF TR-142 v2 (GPON)11 © Genexis BV | all rights reserved
  12. 12. Conclusions •  A three-module integrated CPE is a matched solution to FTTH •  A demarcation point in hardware for the open access operators •  Each module is optimized in functionality and managed independently •  A “click-on” RG allows user self-installation with reduced service calls •  Interoperability is a key requirement at all three FTTH layers •  In-home networks is a next domain to be conquered12 © Genexis BV | all rights reserved
