The aim of this guide is to show a solution for creating a wired data transmission network infrastructure based on GPON technology, using an enterprise network as an example. In this case, an example of deploying a hotel network will be used.
GPON is an access technology that uses a passive optical network (PON) as the transport medium between optical network terminals (ONT) and optical line terminals (OLT). The common components of all PON networks are optical fiber and passive (non-powered) elements such as splitters, combiners, etc. Thus, the key advantage of PON networks is that there is no need to use active elements (amplifiers, signal repeaters) that require additional power in the OLT↔ONT section.
The main advantages of the technology are: the use of a single OLT for multiple subscriber devices, optimal use of bandwidth, as well as higher signal transmission range on the optical network, higher transmission speeds, and higher subscriber density compared to ETTH technologies. GPON technology enables data transfer speeds of up to 2.5 Gbps downstream and up to 1.25 Gbps upstream per GPON port.

OLT. An optical line terminal is station equipment installed at the carrier's communication node. It is used in xPON (GPON, XGS-PON) technology as an aggregation node for connecting multiple subscriber terminals operating on this technology.
ONT. An optical network terminal is subscriber equipment installed at the subscriber's premises.
Bridge mode is an ONT operating mode in which services are transmitted transparently via the ONT. This mode requires additional equipment (PC or router) to be connected behind the ONT. In this connection layout, equipment connected to the ONT's LAN interfaces establishes a direct connection with the carrier's network equipment.
IGMP (Internet Group Management Protocol). A protocol for managing IPTV multicast streams in IPv4 networks.
Multicast is a type of group communication where data transmission is addressed to a group of destination computers simultaneously.
Profile cross-connect is a configuration profile for ONT services that is responsible for forming a logical data transmission link between the OLT and ONT in a specific VLAN.
Profile ports is a configuration profile for ONT services that is responsible for configuring the internal parameters of ONT LAN interfaces, forming rules for traffic passing through ONT, and actions with multicast traffic passing through ONT.
Profile management a configuration profile for ONT services that is responsible for configuring the parameters of ONT interaction with the ACS server.
ACS (Automatic Configuration Server) – CPE automatic configuration server (ONT).
The proposed network section diagram includes a GPON access section for connecting end-user devices. It is assumed that a separate subscriber terminal will be installed in each room. All subscriber terminals are aggregated on an OLT installed in the technical room. Connection to the higher-level enterprise network can be made by connecting to an aggregation switch or directly to a router, depending on the enterprise network architecture. The general diagram will look as follows.
This diagram shows the logical connection between the OLT and ONT. It is assumed that the ONTs will be located directly in the rooms. Up to 128 ONTs can be connected to one GPON channel. Pizza-box format OLTs (LTP-8N, LTP-16N) have 8 and 16 GPON ports, respectively. Thus, the total number of ONTs that can be connected to one OLT is 1024 or 2048 ONTs, which may be sufficient to meet the needs of hotels. ONTs with 4 LAN ports can be used as subscriber terminals. In accordance with the cable plan for rooms, the structured cabling can be configured to have three or four 8P8C RJ-45 sockets in the room, each of which will be switched to a separate ONT LAN port. GPON technology allows each LAN port to be configured separately for specific services, each of which will be provided in its own unique VLAN. For example, the following distribution can be implemented:
This diagram does not include providing Wi-Fi connection via GPON. The implementation of Wi-Fi using access points and an Eltex controller is discussed in the guide Wi-Fi hotel network (hotel Wi-Fi diagram) guide.
This guide does not cover the creation of cable infrastructure. However, it should be noted that the fiber optic line for the GPON distribution network must be designed and constructed correctly with the optical budget taken into account.
Possible variants of equipment to be used for the given diagram include the following:
Following OLT models can be used as the GPON station terminals.
| Model | Number of uplink ports | Type of uplink ports | Number of PON ports | Operation mode of PON ports |
|---|---|---|---|---|
| Eltex LTP-8N | 4 | 4 x 10GE (SFP+)/1GE (SFP) | 8 | GPON |
| Eltex LTP-16N | 8 | 8 x 10GE (SFP+)/1GE (SFP) | 16 | GPON |
Following ONT models can be used as the GPON subscriber terminals.
| Model | Number of LAN ports | Type of LAN ports |
|---|---|---|
| NTU-RG-5420G-Wac | 4 | 4 x 1G |
The choice of this ONT model is determined by the number of ports available on the ONT and the number of clients that need to be connected via Ethernet in each room. These devices have a Wi-Fi module that can be disabled via software. Disabling the module for this configuration is necessary so that the Wi-Fi transceivers installed in the ONT do not affect the radio waves in the rooms and do not create unnecessary interference for the operation of Wi-Fi access points. The procedure for disabling Wi-Fi on the ONT is described in the OLT/ONT configuration section.
Assume that three services – high-speed Internet, IPTV and IP telephony – need to be provided to each room and, accordingly, to each ONT. The architecture for providing services to end users located in rooms is VLAN per service. Each of the services is received by the OLT from the higher-level enterprise network in its service VLAN:
The following VLANs are additionally used:
This diagram assumes that the OLT is included in the enterprise management network. VLAN 100 will be used as an example. It is assumed that this VLAN is also used to manage other hosts in the enterprise network. Depending on the current enterprise network diagram, this VLAN's number can be changed to another during configuration.
This diagram also requires disabling the Wi-Fi modules, which are enabled by default. For this purpose, the built-in ACS (Automatic Configuration Server) on the OLT will be used, interacting with the ONT via CWMP. A template for disabling Wi-Fi transceivers will be created on the ACS server and applied to all ONTs. VLAN 4094, which exists only within the OLT, is configured for ONT interaction with the ACS server.
TV broadcasting in this example is implemented using multicast. It is assumed that there is a multicast source in VLAN 2149 on the enterprise network, or that multicast is supplied by the service provider and enters VLAN 2149 on the enterprise network. Depending on the current enterprise network layout, the number of this VLAN may be changed to another during configuration.
In this example, the telephony service is implemented as a VoIP service by connecting SIP phones to the LAN ports of ONTs in the rooms. It is assumed that there is a SIP server in VLAN 3149 on the enterprise network, or that the VoIP service is supplied by the service provider and enters VLAN 3149 on the enterprise network. Depending on the current enterprise network layout, the number of this VLAN may be changed to another during configuration.
SIP phones are configured manually on the phones themselves or in a centralized manner using the enterprise network or service provider resources. In this case, OLT+ONT act as a bridge for transparent transmission of telephony service traffic to the network.
The detailed diagram of the configuration is provided below.
This section describes the procedures for configuring OLT and ONT functionality. As an example, we will configure the PON part for OLT LTP-16N and three ONT NTU-RG-5420G-Wac to implement this layout. All subscriber terminals in this example are physically connected to the same PON tree on the OLT PON port 1 interface. It is necessary to configure service VLANs on uplink interfaces in which subscriber services are provided for communication with the higher-level enterprise network, as well as on OLT downlink PON interfaces and ONT LAN interfaces for end customers to receive services. The higher-level network, in turn, connects to the provider's network. Internet, IPTV, and VoIP services can be supplied by the service provider.
The initial OLT configuration in terms of management settings for network connection can be performed via the OOB interface or via the console interface. For more details on configuring management parameters, refer to the OLT user documentation and the user manual. Example of configuring OLT management parameters for this layout:

When configuring ONT services in the example, the default bandwidth allocation profile dba1 is assigned. This profile can be used for all ONT services. For more information on configuring dba profiles, refer to the OLT user manual, which can be found on the official Eltex website. |
Please note: Working with ONT in the built-in ACS CLI is done via PON serial ONT. The PON serial display format in the ACS CLI is always in HEX, regardless of the format configured in the main OLT CLI. For example, when the serial number ELTX8500011C is displayed in the main CLI, the same serial number will be displayed as 454C54588500011C in the ACS CLI. If necessary, the PON serial display format in the main CLI can be converted to HEX using the |

The DHCP Snooping feature makes it possible to monitor DHCP user sessions from the ONT. Also, enabling DHCP Snooping is necessary for the DHCP Option 82 substitution feature to work, which allows modifying DHCP user requests by adding additional vendor-specific tags to DHCP packets. A complete list of possible parameters (lexemes) that can be added is provided in the OLT user manual.

Now, let's check out the main sections of the OLT web interface that can be used to monitor OLTs and the subscriber terminals connected to them.
"Monitoring → OLT → Device Information" page: This page displays basic information about the device: hostname, system time, uptime, firmware version, power supply information, built-in sensor temperature readings, fan status, etc.
|
"Monitoring → OLT → IGMP Snooping Groups" page: This page displays information about IGMP groups requested on all OLT ports. The information is presented in two tables:
The number of rows displayed in the table can be changed, and various filters can be applied to the information output.
|
"Monitoring → OLT → System Logs" page: This page contains a list of files with information about system operation (log files). The last 500 lines of the log file can be viewed in the web interface. To view the entire file, you need to download it.
|
"Monitoring → OLT → MAC Address Table" page: This page displays all MAC addresses trained on the OLT. Below the table, the number of rows displayed can be changed to 10, 20, 50, or 100. For convenience, a group of filters or sorting by the selected table column can be used to search for MAC addresses.
|
"Monitoring → OLT → Ports State" page: This page contains three main blocks of information:
The graphical display of OLT makes it possible to perform operations for each port (by calling up the menu with the right mouse button). Reconfiguration and disconnection operations are available for the PON port. For the Front port, only disconnection is available. The PON-port and Front-port tables contain basic information about the status of the ports without the possibility of editing.
|
"Monitoring → ONT → DHCP Sessions" page: This page displays data about currently active DHCP sessions. The information is read-only and only available when DHCP snooping is enabled.
"ONT List" page: This section displays information about all ONTs registered on the device and physically connected to ONT PON channels. Above the table are buttons for creating a new ONT configuration and changing the configuration of existing ONTs as well as quick action icons for ONTs (reboot, reconfigure, reset to factory settings). The icons for operations with configuration and quick actions become active when one or more ONTs are selected. The following icons are available:
– creating an ONT configuration;
– from left to right: delete ONT configuration, reboot ONT, reconfigure ONT, reset ONT to factory settings.
In the table opposite each ONT, an additional context menu of actions with the selected ONTs is available –

Before uploading the configuration to the OLT, the configuration parameters can be edited in a text editor. This way, VLAN numbers, ONT serial numbers and other parameters can be changed.
