18 B-PON & GPON Standards ITU-T G.983 & G.984 Initiated by Full Service Access Network (FSAN) Carrier lead: BT, ATT, NTT, TI, FT, DT, etc Comprehensive specification PHY layer to OAM&P Interoperability initiatives BPON NTT 03/2004, SBC 09/2004, Globalcomm 06/2005 GPON 05/2006 at Telcordia 10 participants 09/2006 in San Jose, CA U.S.A. 12/2006 at ITU Conference in Hong Kong May 7, 2007 at FSAN Lannion France 18

19 EPON Standard: IEEE 802.3ah IEEE 802.3ah Ethernet in the First Mile (EFM) is an amendment to IEEE Comprised of P2P and P2MP (EPON) Additions to the standard for compliance with architecture: Multi-point control protocol (MPCP) - timeslot allocation OAM - Operations, Administration, and Maintenance (OAM) for subscriber access networks Shared-Medium Emulation (SME) or P2P Emulation sub-layer 19

25 OLT and ONT Interoperability OLT and ONTs from different vendors must interoperate Prove standards compliance Lower long term cost via competition FSAN history of interop testing Similar to DSL plug-fests B-PON and now GPON May at Telcordia in N.J. U.S.A. September in San Jose, CA U.S.A. December at ITU Conference in Hong Kong May at FSAN in Lannion France Going on this week 25

26 PON Discovery & Activation Principles 1. OLT opens a discovery window granting new ONTs on PON to communicate with OLT 2. New ONT sends identity and configuration information to the OLT 1 ONT OLT 3. OLT measures Round Trip Time ONT 4. OLT assigns the new ONT an ID and a time stamp (gate for start & stop time) for upstream TDMA N ONT 26

27 Multi-cast Video and IPTV Services FTTH ONT STBs Multicast Multicast source VOD VOD VOD source Multicast channels are transported once and viewed by many Multicast Multicast Multicast Point-to-point service (VOD or data) requires connectivity and bandwidth Multicast of popular channels saves transport and bandwidth Multicast requires 1-to-many switching in the access system Internet Group Multicast Protocol (IGMP) provides multicast (1:many) switching in IP networks 27

28 PON Components Splitters The optical splitter is a passive device Splitters are a main component of PON Depending on the light direction, this device either splits the incoming light and distributes it to multiple fibers or combines it onto one fiber A variety of types are available to meet the architectural requirements of OAN 1X2 1X4 1X8 1X16 1X32 28

29 Other Topics in PON Split ratios 1:32 versus 1:64 Quality of Service (QoS) Security and Encryption Bandwidth Sharing with Dynamic Bandwidth Allocation Multi-Dwelling Unit ONTs Business services Regulation and video franchises Management and OSS interfaces Optical effects of RF video 29
