GPON ONT STANDAR
1.Summary
The ONT is an Optical Terminal Equipment unit for Passive Optical Networks (PON) termination in a (Fiber-To-The-Home) FTTH / (Fiber-To-The-Cell)
FTTC service delivery architecture. ONT communicates with the OLT (Optical Line Terminal) for the PON side and with the customer’s premises for
the client side. This equipment supports triple-play services - high speed internet (HSI), voice (VoIP) and video (IPTV and/or RF Overlay) as like as
implementing the mobile backhaul service in the access component in the FTTC architecture. The use of the GPON ber access technology stan-
dard architecture does allow a signicant service delivery increase when compared with traditional xDSL technology.
The ONT equipment technology is based on GEM (GPON Encapsulation Method), and complies with ITU-T G.984.x. recommendation as like as
G.984.4 (OMCI) ensuring interoperability with major GPON OLT vendors.
These base functionalities, together with the support for bit rates of up to 2.5 Gbps (downstream) and 1.24 Gbps (upstream), a splitting ratio of up
to 1:64 in a single ber and a distance range of up to 60 km, make the GPON technology and the ONT the most ecient option for passive optical
network topologies.
Together with multi-vendor OLT interoperabily (BBF.247 certied), other dierenciated features of the ONT product family are the embeeded RF
Video Overlay as well as the chance to have several TV channel packs by means of using remote managed analog RF video overlay lters. The use
of an embeeded optical reective component also increases probing resolution in case of FTTH probing.
As opposed to the point-to-point architecture, in which there is one physical port per client in the Central Oce, in this GPON point-to-multipoint
architecture there is one single laser and photo-detector in the Central Oce (CO) to serve up to 64 CPEs. All the Optical Distribution Network is
built by means of passive equipment modules with a long MTBF value and very low OPEX costs. This leads to a signicant cost reduction in this
kinf of networks rollout.

2.Technical Description
2.1 ONT Main Functionalities
The ONT is aimed for customer premises and complies with the ITU-T G.984.x recommendation in order to transport (over GPON) and deliver (to
premises domain) the full pack of broadband services.
Broadband service applications are commonly referred as below:
High speed internet (HSI);
Voice (VoIP) services (SIP/MEGACO H.248);
TV (whether IPTV or analog RF video overlay);
Mobile Backhaul.
The multiplay environment is thus reinforced when combining the upper reered services.

2.1.3 Services
The ONT supports the following services:
Voice over IP (VoIP) service;
Broadband Internet Access:
High bit rate data for High Speed Internet service – HSI;
IPTV service;
Analog video service (RF Overlay);
Mobile Backhaul service.
2.1.3.1 Internet over GPON
GPON is a point-to-multipoint passive optical network, in which unpowered optical splitters are used to enable a single optical ber to serve
multiple premises, typically 1-64.
A PON consists of an optical line terminal (OLT) at the central oce and a number of optical network terminals (ONT) at the customer premises.
Downstream signals are broadcasted to all premises sharing multiple bers. Encryption can prevent eavesdropping. Upstream signals are com-
bined using a multiple access protocol (Time Division Multiple Access - TDMA). The OLT queues data to the various ONT terminas in order to pro-
vide time slot assignments for upstream communication.
In Figure 2-4 it is shown a scenario for Internet service user access through an ISP network.
Figure 2-4: Optical ber Internet service user access

10
GPON ONT STANDAR
The communication between client equipment (ONT) and the ISP access routers (MAN edge) is made by an optical ber-based passive architec-
ture (ITU-T G.984 Recommendation). The GPON network acts as a Layer 2 Ethernet metropolitan network. Access network assures and controls
the media (MAC) communication through a TDMA scheme, introducing GEM (GPON Encapsulation Method) in between to adapt TDM layer to
Ethernet.
The used protocol stack is shown in Figure 2-5.
IP
ETHERNET
GEM
TDM/TDMA
Figure 2-5: Stack of protocols for GPON architecture
Several transmission containers (T-CONT) are assigned to each user. Each T-CONT has an associated GEM port and each GEM port has a VLAN
identier and an 802.1p priority level.
The ONT classies the trac depending on the VLAN and the marked priority, and routes it over the corresponding T-CONT/GEM port. Thus for
frame multiplexing, GEM and T-CONT ports are used for uplink while the downlink only use the GEM ports feature.
The CPE architecture is shown in Figure 2-6.
Figure 2-6: CPE architecture
Internet access is provided through the Home Gateway (HG) to obtain a public Internet IP.
The home gateway allocates a private IP address to each client through DHCP, making the addresses conversion through NAT for Internet output.
The home gateway establishes PPPoE session with the ISP network, which authenticates the user for Internet access. The user must be a service
subscriber and the service must be provisioned at the OLT where the ONT is connected to.

EN

2.1.3.2 IPTV service
For the IPTV service the ONT also behaves like a Layer 2 bridging device. For this service, the ONT has a specic GEM PORT for Multicast.This same
GEM PORT is requested by the user in order have access to the various IPTV channels. Every time a user request a new channel, the ONT will send
to OLT a IGMP packet requesting that Channel. The ONT is also responsible for implementing the snooping for the channels that the user requests.
2.1.3.3 RF Video Overlay
PON RF video overlay service is the way to deliver a broadcastTV service over a PON ber network. This video overlay service is foreseen to provide
mainly broadcast video transmission in contrast to unicast and/or multicast IP video transmission which is used for IPTV and/or Video-On-Demand
having the need for a Set-Top-Box or a Smart TV at the customer premises.
Standardization bodies (ITU for GPON and IEEE for GEPON) have excluded the use of the 1550 -1560nm wavelength window for IP transmission on
PONs and have even continued with this approach for the upcoming 10GPON and 10GEPON standards. The 1550-1560nm wavelength window is
thus exclusively reserved for the video overlay transmission and by that mean an option to of¬foad unicast and/or multicast video transmission
from the IP PON transmission link.
Within the ONT RF Video Overlay feature implementation is also an option to deliver a avoured TV channel pack service by the use of a group of
embeeded RF analog lters that can be remotely managed (NMS) in order to enable each individual commercial TV Channel pack, Figure 2-7.

Tipically an extra ber testing signal (1650nm) for optical network probing is also added to the PON optical communication link.
2.1.3.4 Voice
ONT voice service provisioning could be made through OLT congurations over OMCI messages or could be downloaded (FTP) from the OLT up
to the ONT after the ONT registration on the PON network.The ONT bridging family equipments have the ability to deliver the Voice service over
two types of interface:
Logical interface (VLAN encapsulation)
If the ONT has no FXS ports and the VoIP service is transparently forwarded from the OLT up to the Home Gateway (and vice versa) within a pre-
viously dened voice VLAN. ONT respects the dened priority and implements the trac encapsulation from its own Ethernet interface into a
specic T-CONT/GEM-Port over the PON interface and up to the OLT equipment.

12
GPON ONT STANDAR
Physical interface (FXS ports)
The ONT has physical RJ11 FXS interfaces. In this version of the ONT equipment, voice interfaces are terminated in the equipment by means of FXS
(RJ11) connections.The RJ11 analog terminals adapter function is auto/self-congured, integrated (analog/VoIP) and associated with a dened
SIP or Megaco (H.248) user.
The ONT will allowVoIP or NGN (Next Generation Network) trac from devices connected to the RJ11 or RJ45 interfaces, towards the same internal
VLAN.
Appart of the SIP and Megaco (H.248) self-conguration, it is also possible to make modications in the voice service congurations by updating
the ONT SW through download from the OLT via OMCI.
The ONT equipment has a DHCP client (ONT 769503-4GE-2FXS) to get an IP address, alternatively the ONT could be congured with a static IP (ONT
769503-4GE-2FXS). The conguration of the static IP or DHCP client is related to the WAN side and is enabled by the OLT.
2.1.3.5 Multiple QoS per VLAN
The ONT supports 802.1p QoS per VLAN services in which several ows (one per allowed pbit) are embedded in the same VLAN. According to the
applied conguration, the ONT performs a per-ow QoS policy: dropping trac marked with not allowed pbits and limiting to the congured
value the data rate of the allowed ows.
The ONT performs transparent VLAN translation. It is transparent to upper layer protocols, such as ARP, RIP, DHCP, IGMP, PPP, etc.
2.1.3.6 Mobile Backhaul
Due to the large increase on the bandwidth demand of the mobile backhaul networks to support 3G/4G services, PON networks are a natural op-
tion for its access component. ONT also supports this mobile backhaul service by mean of a Layer 2 bridging communication channel. Depending
on the interconnection of the mobile backhaul network architecture, ONT transports mobile data trac over a dened combination of VLAN/GEM
PORT/T-CONT. This same conguration should be known and provisioned at the OLT and upper layer network architecture.
2.1.4 Policing / Rate Limiting.
2.1.4.1 Downstream QoS
The OLT system provides several QoS mechanisms, that can be targeted to the ow characterized by one or two VLAN according with the type of
service, or can be targeted to the packets priority, where each p-bit is mapped in one of eight queues of each port.
For each of OLT ports are associated eight queues, for each of these queues is possible to congure the p-bit mapping in one of the queues, the
scheduler type (Strict Priority or Weighted Fair Queuing) and the minimum and maximum bandwidth of each queue.
In the downstream direction the ingress trac rst passes by a policer congured to each ONT service, which is dened by one or two tags. After
this the trac is put in a queue according with the p-bit/queue mapping. Each of these queues is associated with a scheduler and a policer. Then
the trac ows to the GPON interface and when it arrives to the ONT it will pass by a mapping block which will map the trac in one of the
eight queues according with the p-bits, these queues have a Strict Priority scheduler in order to guarantee that the most prioritized trac passes
rst.
Figure 2-8: Downstream QoS Diagram

EN
13
2.1.4.2 Upstream QoS
In the upstream direction, for eachT-CONT the ingress trac in the ONT passes by a mapping block that maps the trac in one of the eight queues
according with the p-bit, these queues have a Strict Priority Scheduler. The ONT “waits” until the OLT assigns a transmission timeslot for that T-
CONT, so that the most prioritized queues are the ones that transmit rst. In the OLT ingress, the trac is put into a queue according with what
is dened in the queue/p-bit mapping. Each of these queues has an associated scheduler and policer that control the trac sent to the uplink.
Figure 2-9: Upstream QoS Diagram
2.1.4.3 Dynamic Bandwidth Allocation (DBA)
The DBA (Dynamic Bandwidth Allocation) is available in order to optimize the upstream bandwidth. This mechanism consists in dening an ad-
equate T-CONT to the service trac in question. There are ve types of T-CONT, dened by the Fixed, Assured and Maximum Parameters:
Type 1: Only xed Bandwidth;
Type 2: Only Assured Bandwidth;
Type 3: Assured+Maximum Bandwidth;

2.1.5.1 GPON
The ONT GPON layer as G.984.x uses 1490nm downstream and 1310nm upstream of the optical wavelengh, with 2,488Gbps downstream and
1,244Gbps upstream by using an SC/APC protected optical connector.
2.1.5.2 Ethernet
Ethernet is the wired LAN technology and is revised in the IEEE 802.3 standard. At the OSI reference system, Ethernet is at the Data Link layer. In the
ONT equipment the LAN type of physical interface is 10/100/1000BASE-T AUTO-MIX Ethernet type over RJ45 conectors.
2.1.5.3 RF Overlay
Broadcast video signal travels over ber from the CO in the 1550nm wavelength and is demuxed and converted in the ONT to a F conector (75
Ohm) RF Overlay interface to deliver a RFTV signal going from 47MHz up to 862MHz of bandwidth. As it was already referred in one of the previous
sub-chapters, ONT may also implement multiple analog ltering of the RF Interface in order to turn the open RF Spectrum in a group of sliced TV
channels packs that are remotely enabled from the NMS.

3.2 Optical Metering
The equipment measures the downstream received power from the OLT in 1490nm and reports this value through OMCI. The accuracy of the
measurement is +/- 3dBm, maximum. Optionally, ONT has also the chance to have an embeded optical reective component in order to increase
the FTTH probing capabilities in a 50 centimeters resolution factor, which turns to have a single probing system to probe all GPON network ONTs
even when its number increases over Million customers.
3.3 Wavelenght Filtering
The optical interface has WDM lters that allow GPON coexistence with RF video services (1550-1560nm) and the new generation of NGPON1
technology, according to G.984.5 Recommendation.
ITU-T Rec. G987.1 is also granted for XGPON, (following FSAN NG-PON2).
In order to face the nal user´s demands, current GPON networks have to confront the rst evolution in terms of terminals equipments and actual
infrastructure. Migration will be available through a new wavelength planning, by allowing the co-existence of two dierent technologies over
the same ber. The ITU-T Rec. G987.1 provides a mechanism for GPON to XGPON migration with the possibility to achieve 2.5Gbps upstream path.
Nominally downstream will be 10 Gbps.
The next gure depicts the wavelength planning of ITU-T Rec. G987.1
Figure 3-11: Wavelength planning
In order to accomplish to that plan, the upstream wavelength for GPON must be restricted to ONU (ONT) equipment based on the ordinary DFB
lasers, while the XGPON downstream signal range is dened from 1575 nm to 1580 nm and the XGPON upstream signal from 1260 nm to 1280
nm. For the coexistence of XGPON and GPON over the same ber, the CO requires a WDM lter that combines the downstream signal (1490 nm,
1555 nm and 1577 nm), isolating the 1310 nm and 1270 nm upstream signal, with the video signal. Also the wavelength of 1650 nm, used for ber
monitoring, has to be handled.
In addition, ONT devices require the use of a triplexer type transceiver that include an integrated lter or a discrete WDM lter to distinguish the
dierent signals that may be present on the ber. The current networks, equipped with ONT in accordance with the current ITU-T Rec. G984.5, will
be easily updated to XGPON.
Class B+ optical budget are the nominal requirement for coexistence of GPON and XGPON over the same optical ber. Taking in account this re-
quirement, the ber network architecture will not limit the future of the service provider business since GPON architectures, respecting B+ class
of the GPON, are easily updated by placing newest terminal equipments, namely XOLT and XONT, and by replacing the current WDM lter by the
new one in order to handle the new XGPON signals.
XGPON must support/emulate all GPON legacy services in case of total migration.
Like GPON, XGPON is required to support triple play services (data, voice and video), as well as mobile backhauling (accurate frequency/phase/
time synchronization) application through its high quality of service and high bit rate feature capabilities. Access to Ethernet services such as
point-to-point, multipoint-to-multipoint and rooted-multipoint Ethernet Virtual Connection services should be provided. Finally, as a global re-
quirement, XG-PON needs to support IPv6.
3.4 GPON/Ethernet characteristics
GPON/Ethernet characteristics supported, both functional level and GTC-OMCI conguration, corresponds with the general mandatory character-
istics dened in ITU-T G.984.3, G.984.4 and G.988 Recommendation:

4. Setup
4.1 Before installing your ONT device
Check for site’s environmental conditions and look for power and optical access points nearby.
Do not install the device in environments where the temperature or humidity exceeds the standard limits.
This device is a passive cooling device. There are thermal holes in the surface of the box. To prevent the overheating do not obstruct
these thermal holes.
The ONT device is not designed for outdoor setup. Pleae place it in a convenient indoor/cabinet environment.
Use only the provided power kit. The use of a 3rd party power adapter may not guarantee its proper operation.
To avoid any hazard or damage in your eyes, please never look directly into a bre optic connector.
Never assume that the laser beam is inactive or that the optical bre is switched o.
4.2 How to Setup your ONT
The ONT may be installed horizontally on a at surface, wall mounted and ETSI rack (ONT 769503-MBH), quick steps for both of these setups are
described below.
Wall-mount
Remove the ONT lower cover;
Mount the cover on the wall using two screws inserted into the mountings shown in Figure 41(c).The lower mounting is used to regulate
the spatial orientation of the box. The space between the two screws should be about 4.8 cm;
Place the optical cable in one of the openings, (a) or (b) shown in Figure 4-12;
Pass the optical cable, in a clockwise direction, round the circular guide inside the ONT, wrapping it round as many times as necessary;
Fit the ONT into the cover as shown in Figure 4-12;
Attach the ber to the optical connector inside the ONT;
Place a 3 mm plastic clip round the support and the optical cable before the point at which the cable exits the box Figure 4-12(d).Tighten
this just enough to ensure the optical ber will not move;
Close the ONT
