Introduction
The deployment of quadruple-play services over nextgeneration access networks :
1. Increased competition from Service Providers
2. Many new business and service delivery challenges
3. Multiple System Operator (MSOs) Telco and IPTV
Higher BW for Increased Service Offerings
Optical fiber-to-the home (FTTH) or based on a mixed
fiber/copper technology (fiber-to-the curb [FTTC], fiber-to-the
business/building [FTTB])
Reduce the maintenance effort
More reliable than copper

FTTx Technology
(ITU-T) has created several standards for optical access systems based on the PON
architecture, as shown in Figures 2 and 3:
One of the first standards was Broadband PON (BPON). It uses Asynchronous
Transfer Mode (ATM) cells for transmission and has a maximum access speed of 155
Mbps upstream and 622 Mbps downstream.
The latest BPON standard suggests increasing the transmission capacity of 622
Mbps upstream and 1.2 Gbps downstream. However, the consensus is that the
technical hurdle of achieving synchronization at speeds higher than 622 Mbps
upstream is high given the BPON physical layer specification.
FTTx Technology
Therefore, discussion of a new PON specification for gigabit-per-second-class
transmission began in April 2001. Because the new optical access system is capable of
gigabit-per-second transmission, it is called Gigabit PON (GPON), defined in ITU-T
Recommendation G984.
In 2004, The Institute of Electronic and Electrical Engineers (IEEE) defined the
Ethernet PON (EPON), or 10 Gbps EPON (GEPON), standard as part of the
Ethernet First Mile project. EPON uses standard 802.3 Ethernet frames with
symmetric 1 Gbps upstream and downstream rates. EPON is designed for datacentric networks as well as full-service voice, data, and video networks. The IEEE
Task Force P802.3av is currently designing the 10 Gbps EPON or 10GEPON.

Broadband Forum
The Broadband Forum defines technical reports (TRs) and
working texts (WTs) that are related to home management.
One of the key specifications defined by the Broadband
Forum is TR-069.
The auto configuration server (ACS) as defined by the
Broadband Forum, or the Remote Management System
(RMS) as defined by the Home Gateway Initiative (HGI), is
TR-069 capable and provides a TR-069 interface and data
model to remotely control and configure the remote gateway
(RG) and other TR-069-enabled devices located in the home
network (HN).

OMCI is the ONT Management and
Control Interface. The OLT uses the
OMCI to control an ONT. This protocol
allows the OLT to:
Establish and release connections
across the ONT
Manage the User to Network Interfaces
(UNIs) at the ONT
Request configuration information and
performance statistics
Autonomously inform the system
operator of events such as link failures
15
Performance Management
(Diagnostic)
The TR-069 management protocol provides CPE statistics collection via
the ACS to support diagnostics, connectivity, or service issues

Testing Methodologies
Physical Layer Test and TroubleshootingONMS PON
Testing PONs with Optical Time Domain Reflectometers (OTDR)
The OMCI specification determines the status of the ONT and the Physical Media
Dependent (PMD) layer. OMCI requires communications between the OLT and
the ONT. When the ONT does not respond, either due to a fault or because it is
not installed or commissioned yet, it is impossible to determine if the problem
originates in the ONT or the PMD, which explains why many operators require an
external test system that can test the PMD when the ONT is unreachable.
An optical time domain reflectometer (OTDR) can pinpoint the location of faults in a
fiber link and certify the workmanship involved in an installation. OTDRs find and
characterize both reflective and non-reflective events in optical fiber runs by
sending laser pulses of different widths,

PON test system for troubleshooting
How to use the PON test system for troubleshooting.
An operator receives an alarm from the ONT or a call from a
customer.
Using the PON test system, the operator can immediately
check if the fiber is okay.
The operator initiates an OTDR measurement on the
suspected PON and the result is compared with the records
to determine changes in the customers fiber attenuation.
The disappearance of the peak typically indicates that a fiber
cut or additional attenuation is the cause of the problem.
