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 (CATV overlay or video over IP).
The GPON network consists of an Optical Line Terminal (OLT) located at the central office and
a set of Optical Network Terminals (ONTs) located at the customer’s 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,
thereby dramatically lowering the overall costs of deployment for Fiber To The Premises (FTTP)
applications.
In this type of network, subscriber’s voice, video, and data devices are connected to the GPON
via the ONT. The ONT translates IP data and analog voice into 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.
GEM is based on the SONET/SDH Generic Framing Procedure (GFP) for handling TDM, ATM
and Ethernet based traffic without additional encapsulation protocols.
Signal transmission from ONTs to OLT uses a type of time division multiple access (TDMA).
TDMA is a technique used to frame channels of data. In this technique, data communication
sessions originating from multiple points are transmitted in turn. Each data communication
session is assigned a time slot in the TDMA frame and transmits (or accesses that time slot)
only at that time.
In order 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. For overlay TV distribution, a second downstream wavelength
of 1550 nm is used. The ONT employs diplexers (or triplexers, in the case of TV overlay) to
separate the 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 at 2.5 Gbps for voice and data, plus the additional video
overlay wavelength division multiplexing (WDM) signal.

Installation
61187602G2-5A 3
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.
Features
The basic features of the ONT include the following:
• Box-in-box, weatherproof and access controlling construction
• Entry ports for fiber, power and ground, and Ethernet and telephone
• POTS uses in-band signaling tones and currents to determine call status
• System clocks are derived from recovered GPON network clock of 2.488 GHz
• Reports four alarms from the UPS power supply and one door intrusion alarm
• Supports 2.5 Gbps GPON application as per ITU-T G.984.2 specification
• Data services supported by two 10/100/1000Base-T Ethernet interface
• Basic telephone service supported by two POTS interfaces
• 12 VDC power supply

CAUTION
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.

CAUTION
The optical installation is intended to be installed by trained
service personnel only. This is a ‘Class 1 Laser Product’.
NOTE
The 10/100/1000Base-T port(s) and POTS are classified as Type 4
as defined in Appendix B of GR-1089-CORE Issue 4, and is
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 ports and POTS are designed for use as an
intra-building interface only (Type 4 ports as described in GR-
1089-CORE Issue 4) 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.
NOTE
The Total Access 300 2 POTS, 2 GigE ONT (1187602G2) is
designed to operate with nominal operating voltage of 12Vdc and
minimum operating voltage of 10.5Vdc.
