Optical network terminals. GPON technology from Rostelecom: connection and configuration. What is FTTH

Optical Network Terminals (ONT)

Passive optical network is a development that is predicted to have a great future. PON works on the principle of transmitting light signals over optical fiber.

What is ONT Optical Modem?

The architecture of the optical network assumes the presence of a central node module, abbreviated as ONU and ONT devices. In a passive ONT network, the router plays a critical role. A remote ONT node with wifi is used as client equipment in FTTH scenarios. In order to connect external devices, the optical ONT has Ethernet and FXS ports, a connector for an optical cable, Wi-Fi.

The subscriber receives the full resource of the optical cable, which ends up in his apartment, which distinguishes the optical network from the operators of house networks, when the channel allocated to the house is equally divided among all users.

Where is the ONT modem used

Subscriber oNT terminal provides broadband access based on GPON in apartment buildings and whole residential complexes... It also seems appropriate to buy an ONT modem for equipping cottage settlements, office buildings and premises, business centers, student campuses, etc. with the Internet and high-quality telephony.

ONT terminal is an excellent solution for cases when there are technical difficulties for using cable systems, but at the same time you need constant access to the Internet, a network with good bandwidth, high-quality telephony, digital television... When using fiber optic, such tasks can be solved simply and quickly.

The wide scope of operation is due to a rich list of services that can be supplemented by services such as video surveillance, fire alarm etc.

Advantages and capabilities of ONT device

PON technology and, in particular, ONT equipment, has undeniable advantages:

    Adequate total cost of building a network. An impressive number of subscribers can be connected using one fiber optic.

    It is possible to create a distribution infrastructure and lay the foundation for the subsequent development of the network and the provision of a wide range of services. The expansion of the network takes place without damaging the existing system.

    The technology is flexible and can be applied to a variety of FTTx family configurations.

    ONT configuration, equipment maintenance is not difficult and does not require serious costs.

    The bandwidth of the Internet channel is practically unlimited.

    The GPON ONT terminal is highly reliable, which is primarily due to the small number of active elements. For the same reason, the network exhibits low sensitivity to adjacent communication lines.

Today on ONT the price remains relatively high, but due to all the advantages new technology this is fully justified.

Thanks to GPON from Rostelecom, users were able to connect high speed internet on their own computers. You can learn more about the technology by decrypting the abbreviation, which stands for gigabite passive optical network or in Russian - gigabit passive optical network.

GPON from Rostelecom

The basis of the GPON technology from Rostelecom, which has repeatedly received positive reviews both among professionals and users, was laid many years ago. Development began in the 80s of the last century. The tests were first carried out in 1987 in England. The second stage was a consortium in 1995 dedicated to PON standardization. It was attended by developers and the largest Internet providers in the world. Three years after the consortium, the first optical networks available to a wide audience were installed in the United States and Japan. Further, the technology began its rapid development in other countries of the world.

In Russia, the introduction of GPON is now at its initial stage. Active participation this event is hosted by the providers MGTS and Rostelecom. The transition to fiber after long-term use of copper cable is quite difficult, since it requires significant costs for laying new lines and purchasing compatible equipment. Nevertheless, Rostelecom is ready to offer GPON connection not only in large citiesbut also in some private sectors outside of them.

Scheme gPON connections from Rostelecom is quite simple. The provider supplies fiber to each of the houses, and then, using a switch, the cable is divided and fed to compatible hardware user. In the apartment itself, the signal is converted by a special router, which has an input for fiber optic. Such equipment is quite expensive, so users often rent it from a provider.

Important: Before setting up GPON from Rostelecom for your own equipment in home network, you need to connect an Internet operator cable and one computer via the LAN connector. After that, you can log into the device web interface.

Configuring equipment for GPON from Rostelecom

Suitable equipment for GPON connection can be rented directly from Rostelecom. If you are satisfied with this option, the provider will personally configure the network devices in your home. In cases where equipment is purchased separately, setup costs will not be included in the initial connection. Therefore, on the router, you will need to independently enter the Internet parameters.

For successful establishment fiber optic networks should pay special attention to the selection of equipment. The first thing to consider is the functionality of the router. If you need, in addition to the Internet, to also have the ability to connect IPTV and telephony, it is recommended to purchase a terminal. In other cases, a simple fiber optic router will suffice.

One of the optimal terminal models that can be rented or bought from Rostelecom is G PON ONT RFT620. In addition to four LAN ports for connecting computers to the Internet and a built-in Wi-Fi module, such a device will allow you to take advantage of all the advantages of IP and classic telephony.

Having connected the GPON cable from Rostelecom and the computer via the LAN connector, you need to turn on the equipment and go to its settings. To do this, you need to open any browser and write in the address bar of the IP terminal. GPON ONT RFT620 from Rostelecom uses the default IP address 192.168.1.254 to enter the parameter settings. Before entering software the device will need to enter a username and password, which have the values \u200b\u200buser / user. After that, you will be taken to the firmware home page. Internet settings on this model are already predefined by the provider and do not need to be changed.

By default, there is no wireless connection on the equipment, which will need to be activated manually. Wi-Fi on a router from Rostelecom model GPON ONT RFT620 can be enabled in the "Wireless network" menu. Before activating, it is recommended that you pay special attention to the security settings that will help protect your network from intrusion.

GPON technology - a new step in evolution broadband connection to the internet. Thanks to the high speed and stability of the network, users get almost unlimited opportunities for work and play at the computer.

ONT terminal is an end device required when connecting to telephony and / or Internet services. The main purpose of the ONT terminal is to transmit data over optical fiber.

What is ONT / ONU terminal?

ONT router (ONT subscriber terminal) is a device located on the subscriber's side in the GEPON / GPON network. That is, the ONT optical modem is a compact VLAN switch.

The main function of an ONT terminal is to receive packets intended for it from high-speed traffic and send feedback information. Standard ONT terminals are equipped with one port to connect from the GEPON network, and several ports for twisted pair from the subscriber side.

The ONT terminal is installed indoors.

Optical network construction

Depending on the location of the ONT optical modems in relation to the location of the subscriber, the following FTTx technologies for building PON networks are distinguished:

  • to a specific area (FTTCab);
  • to the building (FTTB, FTTC);
  • directly to the subscriber (FTTH, FTTBusiness, FTTO).

For fTTB technologies, FTTCab, FTTK, FTTH (if an optical ONT is installed at the entrance), it is possible to use multi-port optical ONTs (currently up to 24 ports).

ONU / ONT advantages

Each ONT terminal presented in our catalog is equipped with necessary for the user interfaces. These are outputs for IP telephony, Ethernet and Wi-Fi. At the same time, the price set for ONT corresponds to the quality and functionality of the equipment.

You will find a large selection of ONT Eltex equipment on our website of the manufacturer. Here you can also select ONT routers from the GPON subscriber equipment section, ONT optical terminal from the TURBOGEPON station equipment section, ONT subscriber terminal from the TURBOGEPON subscriber equipment section. The availability of models and actual prices for ONT can be obtained from the manager.

What is FTTH?

FTTH (fiber to the home) - optical fiber to the apartment. A terminal is installed in the apartment, and a cable from the terminal to a PC. FTTH is most often organized on the basis of PON technology (abbreviation from English Passive optical network, passive optical network) - a technology of passive optical networks. The PON access distribution network is based on a tree-like fiber-cable architecture with passive optical splitters at the nodes, representing an economical way to provide broadband information transmission.

PON technology - passive optical networks, set-top box "G" - gigabit. They are passive because no active equipment is used on the section from the PBX to the subscriber - the fiber runs to the client's apartment. Due to this, a high throughput channel and, as a result, the ability to connect several services on one line - telephone, television, Internet.

Of course, fiber is not laid with a solid wire from the PBX to the apartment - it would be unprofitable, and the costs of the work done would never have paid off. Therefore, in a certain section of the line, the signal is divided.
To divide the signal, a passive optical splitter was invented - a splitter that turns one fiber into two, four, eight, and so on.

What is ONT?

An optical terminal, ONT, acts as a device that will convert the fiber-optic interface into an Ethernet interface. Depending on the modification, ONT can have functionality from a minimum to a full-fledged router, with the ability wiFi connections, IPTV, telephony and much more from one device. This terminal is installed in the subscriber's apartment.

According to unwritten rules, ONTs are mounted next to the hole where the optics were tightened so that the fiber length around the apartment was as small as possible. Why can't you extend the fiber optic deep into the apartment? It's simple - this thin "wire" is very fragile and extremely sensitive to various bends, bends, pressure (to put it mildly, you shouldn't step on it or put furniture on it). From all of the above procedures, the optical fiber breaks. Fiber recovery and / or replacement is very laborious process... For those who want to connect to the Internet using GPON technology, I strongly recommend - do not stretch fiber around the apartment! Have pity on your nerves and money, as well as the nerves of the company's employees (Internet provider).

Communication between ONT and a computer (if Internet service is connected), as well as between ONT and STB (if IPTV service is connected) is carried out using a copper cable - UTP (twisted pair). ONT, like any other router, needs to be configured. Why do you need to go to it WEB interface and configure it for the services you need (Internet, IPTV, VOIP).
