Introduction

The XGS-PON network belongs to one of the varieties of passive optical networks PON. This is one of the most modern and effective solutions to the problems of the 'last mile', which allows significant savings on cable infrastructure and provides information transfer speeds of up to 10 Gbps in the downlink direction and 10 Gbps in the uplink direction. Using solutions based on XGS-PON technology in access networks makes it possible to provide the end user with an access to a set of services based on the IP protocol along with traditional services.

The main advantage of XGS-PON is the use of a single station terminal (OLT) for multiple subscriber devices (ONT). OLT is a converter of Gigabit Ethernet and XGS-PON interfaces, which serves to connect the PON network with higher-level data transmission networks. ONT is designed to connect customers' terminal equipment to broadband access services. It can be used in residential complexes and business centers.

The line of ONT NTX equipment manufactured by ELTEX is represented by terminals:

• NTX-1 with two UNI (user network interfaces) Ethernet interfaces: RJ-45 10/100/1000BASE-T port, RJ-45 100/1000/2.5G/5G/10GBASE-T port; and one XGS-PON port;
• NTX-1F with two UNI (user network interfaces) Ethernet interfaces: RJ-45 10/100/1000BASE-T port, 10GbE (SFP+) port; and one XGS-PON port.

This user manual describes purpose, main technical characteristics, rules for configuring, monitoring, and firmware updating of optical terminals NTX-1, NTX-1F.

Product Description

Purpose

The NTX-1, NTX-1F XGS-PON ONT (10-Gigabit-capable Symmetric Passive Optical Network) devices are high-performance subscriber terminals designed to communicate with higher-level equipment of passive optical networks and provide broadband access services to the end user. Communication with XGS-PON networks is implemented through the XGS-PON interface, interfaces 10/100/1000BASE-T, 100/1000/2.5G/ 5G/10GBASE-T (for NTX-1) or 10 GbE Ethernet interface (SFP+) (for NTX-1F) are used to connect client terminal equipment.

The advantage of XGS-PON technology is the optimal use of bandwidth. This technology is the next step to provide new high-speed Internet applications at home and in the office. Designed to deploy a network inside a home or building, these ONT devices provide a reliable, high-bandwidth long-distance connection for users living and working in remote apartment buildings and business centers.

The NTX-1 and NTX-1F devices have the following set of interfaces:

Table 1. Interface configuration

Overview

The device has the following interfaces:

• 1 XGS-PON port for connection to the provider's network;
• 1 RJ-45 10/100/1000BASE-T port for network devices connection;
• 1 RJ-45 100/1000/2.5G/5G/10GBASE-T port (for NTX-1) or 1 Ethernet port 10GbE (SFP+) (for NTX-1F) for network devices connection.

The terminal is powered via 220 V/12 V external adapter.

The device supports the following functions:

• Network functions:
  • operation in 'bridge' mode;
  • IGMP snooping support.
• firmware update via the web interface, OMCI;
• remote monitoring, configuration and setup via OMCI.

The device will reboot. Factory settings: LAN IP address is 192.168.1.1, subnet mask is 255.255.255.0. Access is possible from LAN 1 and LAN 2 ports.

Delivery Package

The basic delivery of the NTX-1, NTX-1F device includes:

• Subscriber terminal;
• 220/12 V, 2 A power adapter;
• Installation and initial configuration guide.

Device Architecture

Fig. 5. Logical architecture of the device with factory configuration

Main elements of the device:

• Optical transceiver (BOSA) is designed to convert an optical signal into an electrical one;
• Processor (PON chip) is a converter of Ethernet and XGS-PON interfaces.

With the factory (initial) configuration, the following logical blocks are present in the device (Figure 5):

• Br0;
• eth0…1;
• IPInterface1.

In this case, the br0 block is designed to combine LAN ports into one group.

Eth0..1 blocks are Ethernet ports with an RJ-45 connector for connecting PCs, STB or other network devices. They are logically included in the br0 block.

The Filter and Marking blocks are designed to include local interfaces in one group (in the br0 block). They are responsible for traffic rules: Filter blocks are responsible for incoming traffic on the interface, Marking blocks are responsible for outgoing traffic.

The IPInterface block is a logical object on which the IP address for access to the local network is located.
