Introduction
GPON is a network of passive optical networks (PON) type. It is one of the most effective state-of­the-art solutions for the "last mile" issue that significantly reduces the required amount of cable and provides data transfer with downstream rate up to 2.5 Gbps and upstream rate up to 1.25 Gbps. Being used in access networks, GPON-based solutions allow end users to have access to new services based on IP protocol in addition to legacy ones.
The key GPON advantage is the use of one optical line terminal (OLT) for multiple optical network terminals (ONT). OLT converts Gigabit Ethernet and GPON interfaces and is used to connect a PON network with data communication networks of a higher level.
The range of OLT GPON equipment produced by Eltex comprises of LTP-8X terminal with internal Ethernet switch with 8 GPON ports and RSSI function.
The Operation Manual describes intended use, key specifications, installation, configuration, monitoring, and software update for the devices.

Compatible SFP transceivers
Correct and error-free operation of GPON interface requires exact parameters to be chosen and set for each transceiver type. This can be done only under laboratory conditions by the terminal vendor.
Table 5.1 lists SFP transceivers for which seamless terminal operation is guaranteed.
DDMI (Digital Diagnostic Monitoring Interface) provides information on transceiver parameters, such as temperature, power voltage, etc. DDMI also measures the level of ONT signal (RSSI). All compatible transceivers support this function.

Safety Precautions and Installation Procedure
Introduction
This chapter describes installation of the terminal into a rack and connection to power supply.
7.1 Safety Requirements
General
Any operations with the terminal should comply with the Safety Rules for Operation of Customers' Electrical Installations.
1. Before operating the terminal, all engineers should undergo special training.
2. The terminal should be connected only to properly functioning equipment.
3. The terminal is dedicated to 24/7 operation in environment complying with the following requirements:
-
ambient temperature from +5 to +40°C;
-
relative humidity up to 80% at +25°C;
-
atmosphere pressure from 6.0×104 to 10.7×104 Pa (from 450 to 800 mm Hg).
4. The terminal should not be exposed to mechanical shock, vibration, smoke, dust, water, and
chemicals.
5. In order to avoid components overheating, which may result in terminal malfunction, do not block air
vents or place objects on the terminal.
Electrical Safety Rules
1. Prior to connecting the terminal to a power source, ensure that the terminal case is grounded with an
earth bonding point. The earthing wire should be securely connected to the earth bonding point. The resistance between the earth bonding point and the earthing busbar should be less than 0.1 Ohm.
24
Fig. 7.1 – Support Brackets Mounting
2. PC and measurement instruments should be grounded prior to connection to the terminal. The
potential difference between the terminal case and the cases of the instruments should be less than 1 V.
3. Prior to turning the terminal on, ensure that all cables are undamaged and securely connected.
4. Make sure the device is off when installing or removing the case.
5. Power modules of LTP-X, LTP-X rev. B should be replaced only when the device is powered off. Follow
the procedure in Section 7.2. Power modules of LTP-X rev. C terminals can be installed and removed without powering the device off.
6. Follow the instructions given in Chapter 36 to install or remove SFP transceivers. This operation does
not require the terminal to be turned off.
7.2 Terminal Installation
Check the terminal for visible mechanical damage before installing and turning the terminal on. In case of any damage, stop the installation, fill in a corresponding document, and contact your supplier. If the terminal was exposed to low temperatures for a long time before installation, leave it for 2 hours at ambient temperature prior to operation. If the terminal was exposed to high humidity for a long time, leave it for at least 12 hours in normal conditions prior to turning it on.
Support Brackets Mounting
The delivery package includes support brackets for rack installation and mounting screws to fix the terminal case on the brackets. To install the support brackets:
Step 1. Align four mounting holes in the support bracket with the corresponding holes in the side panel of the device.
Step 2. Use a screwdriver to screw the support bracket to the case.
Step 3. Repeat steps 1 and 2 for the second support bracket.
25
To avoid overheating and provide necessary ventilation of the terminal, sufficient space should be provided above and below the terminal, not less than 10 cm.
Fig. 7.2 – Terminal Rack Installation
Terminal Rack Installation
To install the terminal to a rack:
Step 1. Attach the terminal to the vertical guides of the rack.
Step 2. Align mounting holes in the support bracket with the corresponding holes in the rack guides. Use
the holes of the same level on both sides of the guides to ensure the terminal horizontal installation.
Step 3. Use a screwdriver to screw the terminal to the rack.
The terminal is horizontally ventilated. The side panels have air vents. Do not block the air vents to avoid components overheating and subsequent terminal malfunction.
26
Fig. 7.3 – Power Module Installation
Fig. 7.4 – Installation of Power Modules for LTP Rev. C
Power Module Installation
Depending on power supply requirements, the LTP-8X, LTP-4X rev. B, and LTP-8X rev. B terminals can be supplemented with either an AC power module, 220 V, 50 Hz, or a DC power supply module, 48 V. Location of
the power module is shown in Fig. 7.3.
The LTP-4X rev. C and LTP-8X rev. C terminals can use one or two power modules. Installation of the second power module is necessary when the device operates under strict reliability requirements. In case of using two power supply modules, it is allowed to use different power plants for supplying (with different voltage).
27
As for electric parameters, both places for power module installation are identical. In the context of device operation, the power module located closer to the edge is considered as the main module, and the one closer to the centre—as the redundant module. Power modules can be installed and removed without powering the device off. When an additional power module is being installed or removed, the switch continues operation without restart.
To install a power module:
Step 1. Install the power module into the pocket shown in Fig. 7.3 or Fig. 7.4.
Step 2. Screw the module to the case.
Step 3. Follow the instructions in Section 7.2 to power on.
To install the device:
Step 1. Assemble the device. In case of installation to a 19" form-factor rack, mount the support brackets
from the delivery package to the rack.
Step 2. Ground the case of the device. This should be done prior to connecting the device to power supply. An insulated multiconductor wire should be used for earthing.
