4Carrier 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

9Delivering 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
How does a service provider deliver Ethernet
services to all Enterprise locations?
10What 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
EoPDH enables a common Ethernet service offering
and SLA over both copper and fiber access networks
PDH (Plesiochronous Digital Hierarchy) Term to
collectively refer to E1/E3 and DS1/DS3 copper
access network circuits
11How does EoPDH work?
EoPDH Aggregator
EoPDH CLE
Enterprise Subscriber
Copper PDH Access Network
- 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

- EoPDH aggregator terminates PDH circuits and
provides Ethernet to backhaul network resulting
in improved bandwidth utilization - DCS and PDH Aggregation Router eliminated at IP

Ethernet over E1s
- SDH ADMs / Transport replaced by Ethernet
Transport - Shortest possible Ethernet over E1 (PDH) loops
- CLE at customer premise enables converged
Ethernet and IP services
15Ethernet 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
EoPDH enables ubiquitous, global Ethernet
services over existing copper PDH access network
facilities
16Ethernet Point-to-Point

17A 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?
18What 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
19Benefits 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
20What about fiber management / space?
- ODF for 2304 fiber terminations
- Rack for 1502 active fiber interfaces
- 50 take rate
- up to 100 take rate achievable with second
switch rack
Source Huber Suhner
21What about OPEX?
22But 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

32There is no doubt World goes fiber
- The results of the research evaluating the
sustainability and environmental impact of fiber
networks clearly demonstrate the overall service
and environmental benefits of FTTH. The findings
stand as testament that fiber is a sustainable
and future-proof technology for the 21st
century. - Joeri Van Bogaert, president FTTH Council, 2008
Fiber right now is not just a means to get bits
to the subscriber,it is also a potentially
effective marketing tool. Telecom Strategy
Partners, 2008
33But which technology fulfills best all
requirements?
- Which technology addresses better IPTV and VoIP?
What about legacy TDM? - Bandwidth availability flexibility, capacity
upgrade possibilities - Maintenance fault isolation
- Interoperability multi-vendor networks
- SLA assurance, service protection, and their
associated costs - How to maximize the use of existing
infrastructure? - The access network and future applications

34PON is becoming a leading fibre technology
GPON will dominate in the US, since it is now
certain to be used by both the major ILECs and
many independent telcos. Active Ethernet has some
limited support in the US, but it will remain a
minority technology, taking declining share in
the overall market FTTH Worldwide technology
update market forecast
Because GE-PON is currently the technology of
choice in Japan, it will dominate overall global
FTTH deployments over next few years. FTTH
