NTU Optical Network Terminals 5
1 Introduction
A GPON is a network of passive optical networks (PON) type. It is one of the most effective state-of-the-art
solutions of the last mile issue that enables cable economy and provides information transfer downlink rate up
to 2.5 Gbps and uplink 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 more common 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. ONT is designed to connect user terminal equipment to broadband
access services. It can be used in residential areas and office buildings.
The range of ONT NTU equipment produced by Eltex comprises of the following terminals:
NTU-2V(C) with two Ethernet user network interfaces (UNI): 1 Ethernet 10/100 Base-T port, 1 Ethernet
10/100/1000 Base-T port and 1 FXS port, and also equipped with the integrated Triplexer

transceiver
depending on the device model;
NTU-2W with two Ethernet user network interfaces (UNI): 1 Ethernet 10/100 Base-T port and 1
Ethernet 10/100/1000 Base-T port;
NTU-RG-1402G-W, which are designed to support four UNI: 10/100/1000Base-T, FXS, Wi-Fi, and USB.
This operation manual describes intended use, main specifications, configuration, monitoring, and firmware
update for optical terminals NTU-2V(C), NTU-2W, NTU-RG-1402G-W.
