INTRODUCTION
A GPON is a network of passive optical networks (PON) type. It is one of the most effective state-of-the-
art solutions for the 'last mile' issue that significantly reduces the required amount of cable and provides data
transfer with downlink rate up to 2.5Gbps and uplink rate up to 1.25Gbps. 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 device can be used in residential estates and offices.
The range of ONT NTU equipment produced by ELTEX comprises of the following terminals:
NTU-RG-1421G-Wac, NTU-RG-1431 G-Wac, NTU-RG-1421GС-Wac and NTU-RG-1421G-WZ, which are
designed to support four UNIs: 10/100/1000Base-T, FXS, Wi-Fi, USB, CaTV
