2 Introduction
The 452/454 ADTRAN Optical Network Terminal (ONT) is a Gigabit Passive Optical Network
(GPON) ONT that provides the services detailed below. Figure 1 illustrates the ONT Housing.
2.1 Description
GPON technology provides a consistent and common approach to advancing the public
communications network using:
■ Traditional telephone services (Plain Old Telephone Service (POTS))
■ High speed data services
■ Video services
The GPON network consists of an Optical Line Terminal (OLT) located at the central office,
and an Optical Network Terminal (ONT) located at the customer premises. Between them lies
the Optical Distribution Network (ODN) consisting of fibers and passive splitters or couplers. A
splitter is a device that divides an optical signal into two or more signals. It can also
reassemble signals from multiple signal sources into one signal. The GPON technology is
based on Passive Optical Network (PON) technology.
Traditionally, telecommunication networks use devices that require power to transmit data
from one point to another including processors, memory chips, repeaters, and relays. With
passive optical networks, components that need power to transmit data between the central
office and the customer premises are replaced by passive components that guide traffic based
on splitting optical wavelengths to end points along the way. These passive components, such
as splitters and coupler devices, work by passing or restricting light and do not require power
to transmit data.
In a PON, a single piece of fiber can be run from the serving exchange out to a subdivision or
office park. Then, individual fiber strands can be run to each building. Also, serving equipment
can be split from the main fiber using passive splitters/couplers. This allows one piece of fiber
cable from the exchange to the customer to be shared by many customers. This dramatically
lowers the overall costs of deployment for Fiber To The Premises (FTTP) applications.
In this type of network, subscriber voice, video, and data devices are connected to the GPON
via the ONT. The ONT translates IP data and analog voice into GPON Encapsulated Method
(GEM) frames and combines/splits the signal with analog and/or digital video to and from the
OLT. The signal is split/combined at the OLT similar to the ONT.
Signal transmission from an ONT to the OLT uses a type of Time Division Multiple Access
(TDMA). TDMA is a technique used to frame channels of data. In this technique, data commu-
nication sessions originating from multiple points are transmitted in turn. Each data communi-
cation session is assigned a time slot in the TDMA frame and transmits (or accesses that time
slot) only at that time.
To allow for the transmission of downstream and upstream traffic on a single fiber, different
wavelengths are used for both directions. Downstream traffic uses 1490 nm while upstream
traffic uses 1310 nm. The ONT employs diplexers (or triplexers, in the case of TV overlay) to
separate wavelengths.
Downstream data is broadcast from the OLT to all ONTs. Each ONT processes the data
destined to it by matching the address at the protocol transmission unit header. The
downstream PON signal is broadcast to up to 32 ONTs with a data rate of 2.5 Gbps for voice
and data, plus the additional video overlay wavelength division multiplexing (WDM) signal.

Revision B
In the upstream direction transmission of data must be coordinated between each ONT to
avoid collisions due to the shared media of the optical distribution network (ODN). Data is
transmitted according to control mechanisms configured in the OLT. The aggregate upstream
rate is 1.25 Gbps.

TELEPHONE TROUBLESHOOTING
1. Identify the bad line.
2. Disconnect the plug from the appropriate POTS jack and plug
any working telephone into that jack.
If the telephone works, there is a problem inside the house.
If the telephone does not work, contact your service provider.
3. Remove the telephone and replace the plug into the POTS jack.
4. Close the unit.
This device is intended to be attached to a receiver that is not used to
receive over-the-air broadcast signals. Connection of this device in any
other fashion may cause harmful interference to radio communications
ans is in violation of the FCC Rules, part 15.

CAUTION!
f
Electrostatic Discharge (ESD) can damage electronic modules. When handling modules, wear
an antistatic discharge wrist strap to prevent damage to electronic components. Place
modules in antistatic packing material when transporting or storing. When working on
modules, always place them on an approved antistatic mat that is electrically grounded.
Table 3 shows the configuration codes for the GPON 452/454. The GPON 452/454 is NRTL
listed to the applicable UL standards. The GPON 452/454 is intended for deployment in the
Outside Plant (OSP) at locations where the NEC applies (for example, Customer Premises)
and is intended to be installed by trained service personnel.
This device complies with Part 15 of the FCC rules. Operation is subject to the following two
conditions:
1. This device may not cause harmful interference.
2. This device must accept any interference received, including interference that may cause
undesired operation.
Changes or modifications not expressly approved by ADTRAN will void the warranty.
WARNING!
fThe 10/100/1000Base-T port and POTS port(s) are classified as Type 4 as defined in
Appendix B of GR-1089-CORE, Issue 5, and are suitable for connection to intra-building or
unexposed wiring or cabling only. Do not metallically connect these ports to interfaces which
connect to the Outside Plant (OSP) or to the OSP wiring. The 10/100/1000Base-T port(s), and
POTS port(s) are designed for use as an intra-building interface only (Type 4 ports as
described in GR-1089-CORE, Issue 5) and require isolation from exposed OSP cabling. The
addition of Primary Protectors is not sufficient protection in order to connect this interface
metallically to OSP wiring.
