NTU-2V, NTU-RG 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 terminal equipment of user to
broadband access services. ONT can be used in residential estates and offices.
The range of ONT NTU equipment produced by Eltex comprises of the following terminals:
NTU-2V with two Ethernet user network interfaces (UNI) – 1 Ethernet 10/100 Base-T port, 1
Ethernet 10/100/1000 Base-T port – and one FXS port;
NTU-RG-1402G-W, which are designed to support four UNI: 10/100/1000Base-T, FXS, Wi-Fi, and
USB.
The Operation Manual describes application, key specifications, configuration, monitoring, and software
retrofit for NTU-RG optical terminals and NTU-2V devices.
