Technology of passive optical links PON. Methodology for encouraging xPON to connect the Internet behind pon technology
The PON technology can be used to transmit data by looking at light pulses through a fiber-optic cable. Notebooks, computers and wireless attachments that connect to the WiFi network do not need a built-in module to decode the optical signal. Therefore, for work with FTTH system providers (optical fiber to the house / apartment), special equipment is required.
An optical signal can be converted to an electrical signal with the help of a media converter. There are SC/LC sockets and SFP pairings with TX and RX ports at the input. The signal is sent to the RJ-45 port, through which it is possible to connect a router or another third-party attachment to an additional Ethernet cable. Smaller extensions for connecting home devices via PON affect the visibility of the ONU/ONT subscriber terminal. These stats have a rating of the shortest models of such devices that combine the functions of a router and a media converter.
5th place in the rating: Eltex NTU-2W
The NTU-2W router is a good budget option for a subscriber terminal with WiFi support and IPTV functions. The best model is suitable for a small apartment. Vaughn has only two LAN ports and is not equipped with modern WiFi antennas with a great strength factor. Prote, high arrogance, low price of Eltex NTU-2W, the presence of a USB port and a gigabit Ethernet socket, stun and respect the whole device.
A reminder of the short NTU-2W - a WiFi robot only in the 2.4 GHz band. Obviously, not all portable devices support data exchange on a data rate greater than 300 Mb/s (the boundary value of the 802.11 b/g/n standard). However, the presence of a network at a frequency of 5 GHz could not only increase the boundary throughput of the WiFi building, but it would also improve the signal. This is due to the fact that there is more wireless possession, which is absent, in private apartments, it operates at a frequency of 2.4 GHz, and it can also create a bridge when the channels are interrupted.
Unfortunately, there is only one Gigabit Ethernet socket on this router. The other LAN port is up to the Fast Ethernet standard, and the maximum throughput is 100 Mbps. If you choose a high-speed connection to the Internet (as a real connection to the provider overpasses 100 Mb / s), you should increase the increase to 100 Mb / s for connecting IPTV, and connect the computer through a higher port.
4th place in the rating: ZTE F660
Router with 4 RJ-45 LAN ports and two RJ-11 telephone sockets. The speed of receiving information through the optical interface is up to 2.488 Gb/s, the speed of forwarding is up to 1.244 Gb/s. Supports up to 4 WiFi tiers with different SSIDs, which work at 2.4 GHz. Irrespective of the theoretical possibility of connecting up to 128 clients to the skin, in practice, I will add the necessary parameters to serve a large office network. ZTE F660 is suitable for installation near an apartment or a small office.
This router also has a USB port, which can be used to connect a printer, a flash drive, or a hard drive. Access to the connected storage device is available through the file server or multimedia library. This model of the router can be equipped with the function of automatic diagnostics of the PON connection, which ensures a stable connection of the optical channel. The ZTE F660 bezdrotovy hemstitch also works without problems.
Get respect! Most of the extensions of this model on the Russian market can be upgraded with MGTS firmware. If you want to use a different provider or access to all factory functions, it is recommended to get a global version of the router or change the firmware.
3rd place in the rating: Huawei EchoLife HG8247H
On top of the two front models in this rating, the Huawei HG8247H optical terminal has two omnidirectional antennas and a CATV socket for cable TV connection. One of the official suppliers of the router is the provider Rostelecom. Attachment may be an unexpected change in the optical socket SC. The cable is wound through the opening of that special channel on the lower part of the router, after which it is connected to the socket on the lower panel. Such a scheme protects the fiber optic cable from breaking and attaching a second connector.
The router occupies a high position in the rating of the leader of the silent robot and the great number of functions. There are ventilation openings on all sides of the case to reduce heating. Mustaches of roses are ruffled from the back side. HG8247H provides Internet access via Ethernet and WiFi, the ability to play IPTV digital TV and VoIP Internet telephony. Vbudovaniy intermezhezhevy screen protects the local network from unauthorized access and attacks directed at the robots.
Important! The EchoLife HG8247H software model has been upgraded with dynamic pressure regulation. The power supply of the router changes from 7.5 to 18 W, depending on the flow voltage.
2nd place rated: Sercomm RV6688BCM
On the territory of Russia, the branded model of the router like the MGTS provider is most commonly used. Order from ZTE and Huawei, the Sercomm router is supplied by the provider free of charge with the right to redeem. For some reason, a part of the patched patches on the RV6688BCM web interface is attached to the firmware of the provider. To improve administrative access, you need to go back to the technical support of MGTS. Main characteristics of the PON module:
- Receiver Width (Rx): 2.488 Gb/s;
- Data rate (Tx): 1244 Gb/s;
- Connector: SC/APC;
- Maximum distance from postal worker: 20 km.

GEPON (Gigabit Ethernet PON)- technology of data transmission, which is gaining popularity, by fiber optic cable. The bottom line is that a tree-like topology has a point-rich point, if only one fiber optic channel for dozens and hundreds of subscribers is used to support the network.
The fence tree will be such a rank, so that the wire for the subscriber will be placed on the main highway and closer to the junction. For the bottom of victorious passive splitter - splitter. It is important to consider the significant topology of the fiber optic tether, as it is more important to use a point-to-point architecture, and the skin line decontamination will require the installation of an active tethering system.
GEPON structure
For stimulating optical passive mesh, fiber optics, vikoristovuyutsya:
- OLT(Optical Line Terminal) - optical line terminals that provide communication between PON and external lines;
- Modules SFP OLT for PON connection, with greater attenuation and signal coding;
- ONU(Optical Network Unit) – terminal block (modem) at the subscriber.
- Splittery- passive rozgaluzhuvachі at the knots of the merezhі.
The tree-like structure of GEPON transfers a variety of options, in the simplest - 1 OLT, 1 SFP OLT module, 64 ONU and the required number of splitters for splitting up to "multi-stem", if all ports of the OLT, as well as a number of OLT ports, are available.
Scheme of the architecture of the GEPON network:
The image also shows the actual transmission method. All packets go to the central node, at the end point of the skin ONU "takes" less than its own, identification identifiers.
On the return route, packages from subscribers are collected up to one channel. At the pon merezha zastosovuetsya TDMA protocol if packets from different points are transmitted at a different time.
In addition, incoming and outgoing traffic is divided, as well as TV traffic.
Scheme of the folding structure of GEPON:
When designing folding schemes for passive fiber optic networks, it is important to remember that one channel cannot be extended more than 64 subscriber extensions, and that the optical budget of the system should be protected.
Optical Budget systems - the difference between OLT transmission intensity and sensitivity to ONU reception.
Max., on a yak, you can stretch a passive optical line, with the cost of the channel 20 km.
Maximum number of subscriber attachments, which are connected to one "tree" PON - 64 . However, the last number of subscribers can be larger, as if the ONU connected a switch. Here, the exchanges are superimposed only by a table MAC-address of OLT and ONU, and, of course, the bandwidth building of the channel.
Minimum speed per 1 subscriber- 16 Mb/s (1024 Mb/s for 64 ONUs).
Installation for GEPON mesh
Optical line terminals - OLT
These extensions are lamps of a different level, equipped with Uplink ports - for connecting with external data ports (Internet, TV, telephony) and Downlink - for PON networks.
OLT-terminals are released with the following icons:
- AC - for the life of the commutator, a standard electrical circuit for 220 V is used;
- DC - the terminal needs a constant stream 36-72V;
- 2-AC 2-DC - the presence of 2 dzherel zhivlennya, the main one and backup.
Subscriber terminals (modems) - ONU
Attachments on the subscriber's side, optical terminals, equipped with one PON port, and one or a dekilkom port, depending on the model, ports for connecting the client's equipment. Іsnuyut models from the output of cable TV.

Splittery
Inexpensive, compact, simple extensions that do not depend on electricity, a thermal closet, control and installation. Їхнє smut zavdannya - sent traffic to the route from the provider to the subscriber, and zmіshannya traffic - to the return one. Buvayut zvarnі (because of the possibility of uneven distribution of traffic) and planar (equal shoulders). Razgaluzhennya - from 1 * 2 to 1 * 128.
Shortfalls in technology
- Extinguishing the signal on the skin node of the discoloration. At the result of a measure on 64 ONUs, the overburden can be overwhelmed by 20 dB.
- The need for maximum throughput capacity of all outbuildings. If a particular subscriber wants to allow 16 Mb/s, the network skin point (ONU) is set to trim the maximum GEPON throughput of 1 Gb/s.
- Insufficiently high riven for the safety of the data. Technology is insanely not suitable for financial and similar organizations.
- The complexity of modernization. To increase the throughput of the building, you may need to replace the entire cable on the main line.
- Switch to all PON robots with one faulty ONU attachment, which transmits an uninterrupted light signal at the gate. You can use WathDog to control vipadical breakdowns, or even better to protect the evil spirits.
- The complexity of the manifestation of faults. Splitters, calling for their supernatural simplicity, unexpectedly helped with the designated slaughter house of the merezha.
GEPON benefits
- Economical fiber optic cable. In fact, the GEPON technology allows for the shortest possible length of the cable infrastructure to a greater extent.
- Visibility of active possession at the nodes of the merezhі, which essentially reduces the cost of maintenance.
- Highly pіdtrimuvana shvidkіst- Up to 1 Gb/s.
- Efficient rozpodіl navantazhennya at the canal. Theoretically, the speed of the skin subscriber becomes the bandwidth of the channel / the number of subscribers. In fact, as a matter of fact, subscribers at once won't win all their smug traffic, otherwise they won't connect to the call - the security of the solution will increase.
Like Bachimo, GEPON has its pros and cons. However, the growing popularity shows that a lot of people know more pluses.
In one of our upcoming releases, we will see a passive fiber optic mesh on the power supply part.

How to use GPON
Providing access to the Internet using GPON technology transfers the replacement of obsolete mid-wire cables to more advanced fiber optics, which can significantly increase the throughput of the building. The signal with such a cable to pass behind the help of a light, and not an electric pulse. The light impulse passes through the glass fiber, ensuring the highest signal and high speed at low energy consumption.
The installation of the GPON router transfers the fiber optic cable directly to the subscriber's apartment, and not until all future days, which guarantees permanent access to the Internet and prevents accidents in robots through rewiring. To connect to the GPON technology, the subscriber needs to install a modem - ONT (Optical Network Terminal) without cost, to connect all services to the subscriber in one extension. When connected to a Wi-Fi router, you can use it without darts from any kind of attachment.
Prospects for development
Today, we can say with confidence that GPON technology is not only keeping up with the times, but rather in what it excels in, expanding the boundaries of what is possible. The new shipping standard allows you to gradually update the package of services. One of the main reasons why you should buy GPON is the lack of security access to video surveillance, telemetry, security alarms and other services. Resources of technology allow us to talk about the prospects for the development and supply of riches of other services for a better life.
