Chapter 1.
Introduction
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 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.

13
Chapter 2.
Intended Use
The LTP-8X/4X optical line terminal is designed to establish connection with upstream equipment
and provide broadband access across passive optical networks. Ethernet connection is established
through Gigabit uplink and 10G Base-X interfaces; GPON interfaces are used to connect to optical
networks. Each PON interface allows connection of up to 128 subscriber optical terminals through
one fibre and supports dynamic bandwidth allocation (DBA).
The following services are provided to end users:
— voice communications;
— HDTV;
— VoIP;
— high-speed access to the Internet;
— IP TV;
— video-on-demand (VoD);
— video conferencing;
— online educational and entertainment programs.
The device has the following functions:
— dynamic bandwidth allocation (DBA);
— support for quality assurance mechanisms (QoS), Strict priority + WRR, GPON ports
prioritisation for different types of traffic according to 802.1p;
— security functions;
— ONT remote control, automatic detection of new ONTs;
— FEC errors correction;
— power measurement support for signals received from each ONT (RSSI) 1;
— VLAN organisation (VLAN ID range: 0–4094);
— MAC address filtering, 16,000 entries in the MAC table;
— support for IGMP snooping v1/2/3, IGMP proxy;
— support for DHCP snooping, DHCP relay agent;
— support for PPPoE IA;
— support for Jumbo frames up to 2000 bytes (supported on NTU-1 and SFP-NTU-100).

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.
