This document discusses power saving methods in EPON (Ethernet Passive Optical Network) fiber access networks. It outlines the need for power savings due to the large power consumption of ONU (Optical Network Unit) devices and regional guidelines. It describes power saving mechanisms at the device level including components power gating and clock gating, and at the network level using ONU sleep modes controlled by the OLT (Optical Line Terminal). The document evaluates the power savings effectiveness of ONU sleep modes and shows savings increase with longer sleep durations if connectivity is maintained.

This presentation discusses market trends and its impact on Network infrastructure, Cisco carrier Ethernet Transport Architecture, Cisco carrier Ethernet portfolio and TCO Leadership.
Active optical networks have advantages over passive optical networks in terms of bandwidth. With AONs, bandwidth allocation is flexible and each subscriber can be allocated from 100 Mbps to 1 Gbps. In contrast, PON bandwidth is determined by the splitting factor, with each subscriber receiving less bandwidth depending on the number of subscribers on the network. Upgrading bandwidth is also simpler with AONs, as subscribers can be upgraded by changing fiber optic leads or boards. However, PONs allow for higher subscriber counts due to their point-to-multipoint topology.

Passive Optical Network: FAQ’s
What is Passive Optical Network?
Passive Optical Network (PON) is a type of fibre-optic access network. A PON reduces the amount of cabling and equipment required compared to an active optical network, where each user has a separate connection to the network hub. Generally, a PON configuration contains an optical line terminal (OLT) at the service provider's central office and a number of optical network units (ONUs) or optical network terminals (ONTs) near end users.
How does it work?
PON uses an optical splitter to allow multiple subscribers to share a single fibre connection to the service provider's network. Furthermore, the splitter is a passive device that does not require any power.
The OLT contains a laser that sends an optical signal down the fibre to the splitter. As a result, the splitter then separates the signal into multiple signals, each of which is sent to a different ONU or ONT.
The ONU or ONT converts the optical signal back into an electrical signal that can be used by the customer's equipment.

2. EPON is a Universal Access Architecture
All user types
– Residential
– Business
– Cellular backhaul
All configurations
– SFU
– MDU/MTU
– FTTH
– FTTC/FTTN
All Data Rates
– 1 Gb/s (.3ah-2004)
– 10/1 Gb/s (.3av-2009)
– 10/10 Gb/s (.3av-2009)
One architecture simultaneously supports all user types,
all deployment configurations, and all equipment
generations on the same network!
20 April 2012 IEEE P1904.1 Seminar, Prague, Czech Republic 2
3. Motivation for Protection in EPON
With the increasing rate of deployments of EPON systems
to support both residential and business applications,
service protection becomes of paramount importance to
maintain the QoS and high availability of these applications
A network can offer protection by providing backup
resources to be used when the primary resource fails.
Survivability is property of a network to be resilient to
failure
– Requires physical redundancy and protection switching
mechanisms
Survivability is a very important aspect of modern networks
– The ever-increasing bit rate makes an unrecovered
failure a significant loss for network operators.
– No network-operator is willing to accept unprotected
networks anymore.
20 April 2012 IEEE P1904.1 Seminar, Prague, Czech Republic 3
4. EPON Failures
The common EPON failures are:
– Fiber cut in feeder/drop fiber, which affect users connected to the
given fiber trunk/branch;
– Failure of OLT/ONU transceivers, affecting either all or selected users;
– Failure of other passive optical components, e.g. Passive Splitter
Combiner (PSC), connectors, splices etc.
– Different types of OLT/ONU failures, related with all other electronic,
electric or mechanical components of these devices, including among
the others, ASIC, connectors, power supplies etc.

5. Failure Detection in EPON
Fiber Plant monitoring using OTDR
– Active Monitoring
– Used for both fault detection and localization.
– Not specified by SIEPON.
Transceiver Status Monitoring
– SIEPON provides network operators with ability to
monitor major optical transceiver parameters for both
OLT and ONU.
Link Fault Detection
– BER Measurements.
– Failure to receive valid optical signal for more than 2ms.
– Loss of single REPORT/GATE messages within 50 msec.
20 April 2012 IEEE P1904.1 Seminar, Prague, Czech Republic 5
6. SIEPON Protection Techniques
Two types of Optical Link Protection are
introduced by SIEPON:
– Trunk Protection
– Tree Protection
Both OLT intra-chassis and inter-chassis (dual-
homing/parenting) protection are supported.
– Inter-chassis communications protocol is unspecified by
SIEPON.
Both on-demand and automatic protection
switching are supported.
Both Line and Client Protection are supported.
– Key difference depends on whether the MAC client block
uses combinatorial or sequential logic.
20 April 2012 IEEE P1904.1 Seminar, Prague, Czech Republic 6
7. Line Protection
In Line Protection Scheme, the entire MAC Client data path is shared
between primary and backup paths. For example, queues and shaper/policer
are shared between primary and backup paths.
Line Protection Scheme is functionally equivalent to an implementation
where a protection switch is located within an ONU ASIC containing two line
interfaces
20 April 2012 IEEE P1904.1 Seminar, Prague, Czech Republic 7
8. Client Protection
In Client Protection Scheme, the entire MAC Client data path is fully
decoupled.
Upon protection switchover event, the backup path starts with clean history
Client Protection Scheme is functionally equivalent to an implementation
where a protection switch connects to two separate ONU/OLT ASICs, each
with a single line interface
20 April 2012 IEEE P1904.1 Seminar, Prague, Czech Republic 8
9. Trunk Protection
Trunk Protection
ONU is not protected.
The OLT and trunk fiber are duplicated.
Protection area Backup OLT can be in hot or cold stand-by mode
Switching time must not exceed150 msec.

10. Tree Protection
Tree Protection To balance traffic loads of different ONUs between
OLT, ONU and the entire fiber plant are two OLTs, a single OLT can act as working OLT for
protected against failure. some ONUs, while simultaneously act as stand-by
Only Hot Stand-by mode is supported. OLT for other ONUs.
Switching time must not exceed 50 msec.
20 April 2012 IEEE P1904.1 Seminar, Prague, Czech Republic 10
11. Applications of SIEPON Protection
Trunk Protection
– Switch over time is <= 150msec.
– Frame loss is allowed.
– Most suitable for residential deployments
where tree protection is too expensive due to
high number of fibers in the drop section.
Tree Protection
– Switch over time is <= 50msec
– Frame loss is minimized.
– High-end business users.
– Mission Critical applications.
