Carrier Ethernet Access Technology Shoot-Out
Copper PDH vs. Active Fiber vs. PON
2. Panelists:
3. Access Shoot Out IntroductionPanel 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 subscribers WAN connectivity
Provides IT friendly Ethernet (UNI) instead of E1 TDM circuit
Simplifies Providers 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 everybodys 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

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 PONPON 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
