I recently took some time to visit with Greg Bathrick of Calix. Greg is the chair of the Broadband Forum (BBF) Fiber Access Networking work area and spends a lot of time with the G.fast and NG-PON2 standards bodies. We discussed recent trends related to copper access technologies, like G.fast coming together with NG-PON2.
TERESA: Greg, you recently spoke at a primarily copper access conference, yet you were talking about NG-PON2, what was the key message?
GREG: The Ultra-fast Broadband Seminar primarily attracts service providers in and around Europe. FTTH hasn’t been widely deployed in Europe, but European service providers are very interested in how to get more bandwidth for 5G mobile backhaul as well as to the large quantity of MDU’s within Europe.
TERESA: In your conversations at the conference, what were some of the examples of how NG-PON2 and G.fast might be applied together?
GREG: In Europe, uplink requirements are increasing as G.fast is deployed within large MDU’s for Gigabit services, this leads to more capacity being required to the buildings. NG-PON2 is an excellent technology for delivering high bandwidth to large MDUs to then connect to the G.fast systems. In addition, the ITU-T SG15 Q4 is working to release newer versions of G.fast and NG-PON2 has enough capacity today and in the future to more than meet the needs.
TERESA: What are some of the challenges that the Fiber Access Network (FAN) work area is focused on addressing?
GREG: GPON never really achieved market wide interoperability. The lack of interoperability limits service provider ability to move fast against competition due to supply and other issues. We are therefore focused interoperability. The second XGS-PON/NG-PON2 interoperability plugfest is planned for later this year and the BBF.247 PON certification program will be extended to include XGS-PON/NG-PON2 by 2018.
TERESA: In your session on NG-PON2, what were some of the key discussion points with the audience?
GREG: There was significant interest in a common network management strategy to ease back office integration. Having a common approach across GPON, NG-PON2, G.fast and other access technologies, reduces limited IT resources and accelerates time to deployment. The BBF is committed to having all working areas share the same underlying YANG model.
