    1. Carrier Ethernet Access Technology Shoot-Out Copper PDH vs. Active Fiber vs. PON

    2. Panelists:

    3. Access Shoot Out Introduction Panel Moderator:

    4. Carrier Ethernet in the Access, Metro & Global Networks Carrier Ethernet Services operate independently of the physical networks they run across making expansion to new technologies easy Creates a single service connection from Enterprise or business office, in a single person office, or home or on the road. In the Metro and First Mile, Ethernet is becoming the network of choice with migration from Frame Services

    5. Ethernet over Different Access Network Technologies

    6. Carrier Ethernet Scope and Reach COPPER, FIBER, EPON, WIRELESS, COAX CABLECOPPER, FIBER, EPON, WIRELESS, COAX CABLE

    7. Carrier Ethernet in Access Networks Active areas in Carrier Ethernet development Ethernet Access for Mobile Backhaul Ethernet over Active Fiber Ethernet over Passive Fiber (PON) Ethernet over Copper PDH (E1/DS1) Ethernet over Copper DSL Ethernet over Hybrid Fiber Coax (HFC)

    8. Converged Ethernet/IP Services over Copper PDH Access Networks

    9. Delivering Ubiquitous Ethernet Services - The Access Network Challenge Ethernet over Fiber (EoF) access networks The optimal technology for delivery of Ethernet services Unfortunately, not all Enterprise sites have fiber access However, they all have access to copper/PDH circuits

    10. What is Ethernet over PDH (EoPDH)? Technology that enables delivery of Ethernet services over PDH (E1/DS1, E3/DS3) access networks Service Bandwidth Granularity N x 2Mbps (N bonded E1s), N x 1.5Mbps (N bonded DS1s) N x 32Mbps (N bonded E3s), N x 45Mbps (N bonded DS3s) Example: 5 bonded E1s provide a 10Mbps Ethernet service Supports same MEF service attributes as EoF services Ethernet UNI to subscriber Granular bandwidth and QoS per service Fault Management and Performance Management for SLAs

    11. How does EoPDH work? Ethernet Frames enter UNI on EoPDH CLE and encapsulated in GFP Access Network multiplexes E1s into channelized STM-1 circuits E1s in STM-1 circuits terminated on EoPDH Aggregator GFP terminated, Ethernet frames reconstructed EoPDH Aggregator adds S-VLAN tag (QinQ) and passes Ethernet Service Frames to Ethernet Transport Network

    12. Ethernet L2 Services and Ethernet Access to IP Services over E1s PDH circuits: PMO

    13. FMO Step 1 in Network Evolution to Carrier Ethernet

    14. FMO Step 2 in Network Evolution to Carrier Ethernet

    15. Ethernet over PDH Benefits Simplifies Enterprise subscriber’s WAN connectivity Provides “IT friendly” Ethernet (UNI) instead of E1 TDM circuit Simplifies Provider’s Access/Aggregation Network Terminates TDM PDH circuits as close to subscriber as possible “Media conversion” (Ethernet?TDM?Ethernet) performed between EoPDH CLE and Aggregation Device Improves backhaul bandwidth utilization

    16. Ethernet Point-to-Point

    17. A technology fairy tale Once upon a time in the last century... Fiber was expensive and had to be shared Optical transceivers were expensive and had to be shared Few 10s of Mbit/s were considered more than enough to satisfy everybody’s bandwidth appetite ITU-T and IEEE developed various flavours of PON In the world as we know it today... Fiber is cheap Optical transceivers for FE and GE are cheap Typical access bitrates grow 50% YoY reaching 100Mbit/s before the end of this decade and 1Gbit/s before the end of the next decade Compelling reason for PON?

    18. What is Ethernet Point-to-Point? Direct star connectivity between POP and subscriber topology similar to telephone access network Using standard Ethernet technology (FE, GE, ...) over single strand of single-mode fiber

    19. Benefits of Ethernet point-to-point Simplicity Virtually unlimited bitrate per subscriber Fiber is neutral with respect to transmission technology Migration to higher speeds or new technologies on a per-customer basis Pay as you grow Open Access to fiber inherently embedded in the architecture Flexible, Future Proof

    20. What about fiber management / space?

    21. What about OPEX?

    22. But I want to share fiber! Most natural way of sharing a fiber is in wavelength-domain DWDM-PON technology available economically viable within 2 years Ethernet Point-to-Point per wavelength Combines best of both worlds

    23. Ethernet over WDM-PON

    24. WDM PON network architecture

    25. Benefits of WDM PON technology Scalability through bitrate and protocol independency Upgrade path on a per service level High degree of security and privacy Simple and straightforward network planning Geographical flexibility with long reach capability Architecture supporting open access networking Standard Ethernet technology and inter-working

    26. WDM PON options Power splitters vs. filters in remote node Lambda grid options – DWDM, CWDM, … Bit rate per wavelength – 1G, 2G5, 4G3, 10G Colored or colorless ONU design Underlying TDM scheme for high fan out Protection options for highest availability Optional amplification for extended reach

    27. Optical access applications

    28. Eliminating active equipment and freeing up real estate

    29. Smart service termination

    30. Summary Simple, open and dedicated point-to-point connectivity Efficient and future-proof transport architecture optimized for access networks Utilized leading edge technology to reduce both capital and operational cost

    31. Ethernet over PON

    32. There is no doubt: World goes fiber

    33. But which technology fulfills best all requirements?

    34. PON is becoming a leading fibre technology

    35. All over the world operators go for PON PON subscribers will dominate ptp subscribers

    36. What is PON? Created by the FSAN organization (driven by service providers & operators); Standardized by ITU-T (A/BPON, GPON) or IEEE (EPON) Bandwidth >100Mbit/s per subscriber through DBA PON optimized for multicast and „downstream intensive“ traffic Cost-optimized support of multiple (legacy and new) services through various subscriber interfaces: VoIP (SIP, H.248), video (IPTV, cable TV), data Support of all types on in-house cabling: copper TP, CAT5, fiber Real multi-service platform: in the 1st mile and in the CO Easy upgrade to more subscribers and higher bandwidth Clear migration path to NG-PON PON is a „green“ technology

    37. PON is the ideal solution to backhaul mobile traffic

    38. The TCO advantage of GPON
