Not so long ago used for high-speed data transmission. Previously, not every user could afford to install a separate terminal in his apartment that worked only for him.
In this regard, Internet providers "launched" an optical cable in apartment house and connected it to the network module, and already copper wires or twisted pairs, transmitting the flow of information, departed from it to the apartments. At the same time, the data transfer rate dropped significantly. But with the creation of FTTB connectors, the situation has changed dramatically.
for optical cable
Now every resident of the city can afford a separate fiber optic router. But at the same time, another question arose: how to transmit an Internet signal via Wi-Fi, for example, to connect a tablet, smartphone or laptop? To solve this problem, you need to buy a router with a built-in Wi-Fi module. But a wide range of products on the market can shock even an experienced user.
In order not to get lost in the whole variety of devices, you need to determine what, in your understanding, means best wifi router? Perhaps this is a combine that can easily provide high-speed Internet from a dozen devices? Or will it be a compact device with an optimal ratio of price, functionality and durability? To help you figure this out, let's define what parameters a fiber optic router with WiFi should have.
Ports and Bandwidth
Previously, when an optical cable was first brought into an apartment building, connected to a terminal, and only then transmitted an Internet signal to apartment owners, an FTTH port was used. Not so long ago, a new format was developed - FTTB, which allows you to connect optical fiber to a router located in your home. To connect directly to the router, two groups of ports are used - WAN and SFP.
The first group is the most common. Outwardly, the WAN port is a regular connection connector. However, before making a purchase, check with your provider what kind of WAN port is needed for connection. A fiber optic router equipped with an SFP connector is suitable for connecting any cable, as it is a standard format.
When choosing a router with a WAN port, you need to make sure that the throughput is not lower than the signal speed that your operator guarantees you. Otherwise, you risk overpaying for the Internet. SFP connectors provide data reception at speeds up to 1 Gb / s and provide optimal throughput for any connection.
WiFi standards
Having chosen a router with high bandwidth, you need to decide on it, otherwise a situation will arise when the router can receive a high-speed signal, but it cannot distribute it to mobile devices via a Wi-Fi network.
Therefore, when purchasing a fiber optic router, make sure that the wireless interface standard matches one of the following:
- IEEE 802.11b - create a Wi-Fi network with a data transfer rate of up to 11 Mbps;
- IEEE 802.11g is a higher speed protocol providing speeds up to 54 Mbps;
- IEEE 802.11n is the most advanced standard in existence, transmitting a signal at speeds up to 300 Mbps.
When choosing a router in a store, you need to make sure that the Wi-Fi speed guaranteed by the device is not lower than the Internet speed that the operator provided you with. Now let's look at the most popular router models among customers.
D-Link-615 router series
D-Link is one of the leading suppliers in domestic market internet equipment. Its products are noted by users for the best value for money.
When choosing a fiber optic router for the first time, take a closer look at the DIR-615 model. A simple and intuitive interface simplifies setup. The radius of "distribution" of a Wi-Fi signal with a speed of up to 300 Mbps with two antennas will be enough to cover the entire area of the apartment. There is a built-in IPTV function for watching interactive TV.
Another outstanding representative of the series is D-Link DIR-615/FB. The router is equipped with a WAN port and two antennas that provide signal distribution over a fairly large area at speeds up to 300 Mbps, it has a LAN connector for cable Internet connection.
D-Link routers for high speed internet
The D-Link DVG-N5402GF fiber optic router is one of the best, adapted for high-speed data transfer. It is equipped with 4 ports that provide signal reception at speeds up to 1 Gb / s, a WAN format connector. It has a Wi-Fi interface of the 802.11n standard, which causes data transfer at speeds up to 350 Mb / s. Two detachable antennas cover a large area.
The D-Link DIR-825/ACF router uses an SFP connector to receive data, so the speed WiFi sharing reaches 1167 Mbps with simultaneous connection of up to 4 devices to the network. USB interface can be used to connect MAC address filtering capability and advanced security protocols will protect your network from intrusion.
Routers from the provider
Some providers, when connecting a fiber optic cable, offer their own fiber optic router. Rostelecom, Beeline, MTS are well-known operators who supply their equipment at the time of subscription. However, the connection cost increases significantly. In order not to overpay, you can choose your router, because there is no difference from which manufacturer to use the device.
At the same time, it must be remembered that the parameters of the input signal correspond to the guaranteed data transfer rate. As the most optimal option, we can advise Mikrotik RB2011UAS-2HnD-IN with an impressive appearance and original design.
An alternative could be Huawei EchoLife HG-8240. It has multiple slots for connecting devices by local network, a special port for interactive television and provides data transfer rates up to 1Gb per second.
Features for optical fiber
In some cases, when connecting the Internet, a terminal can be installed inside the apartment. Employees of the provider company themselves install such a device and connect fiber optics to it. Which router to choose and how to connect it to the terminal is up to you.
First you need to combine the selected router and optical terminal. This is done with a cable. If an optical network has been installed in your home, then this can be done through an optical outlet. After that, the router connects to the computer and the connection to the Internet is checked:
- Open command prompt as administrator.
- Run netstat -e -s followed by ping google.com.
After that, it remains to check the speed of the Internet signal. To do this, open the "Task Manager" and select the "Network" tab. If the connection speed matches the one guaranteed by the provider, then you have taken into account all the recommendations on how to connect the fiber to the router and have chosen the right router.
If you are a high speed internet user GPON technologies, then your router has LOS indicators and PON (depending on the device model, there may be only PON). They show the status of the Internet connection and signal problems on the line. How to decipher the signals they give, we will tell in this article.
The meaning of LOS and PON on the router
First, let's briefly talk about what GPON is. This is a high-speed connection via fiber optic cable, except for the Internet, which allows you to use telephony services and digital television. The optical cable is brought directly to the user's apartment or office, where a special ONT modem is installed, in fact, it is a Wi-Fi router connected to the fiber optic line. It connects directly to the provider's equipment (OLT) via optical fiber.
In addition to the main indicators, the same as on conventional routers, the ONT modem has LOS and PON indicators that display the status of connection to the OLT.
Description of the display
During normal operation, the PON indicator should be solid and the LOS indicator should be off. The LOS light is responsible for the connection, while the PON is for registering with the provider's network.
Consider possible options indications:
- LOS and PON indicators are off - there is no connection to the OLT, the optical cable is not connected to the connector or there is no signal in the cable.
- PON flashes quickly, LOS is off - the router is trying to establish a connection with the provider's equipment.
- PON lights up continuously, LOS is off - connection with the provider is established.
- Both indicators are blinking frequently - it was not possible to pass identification on the OLT, incorrect binding of the router using GPON technology. To resolve the issue, contact your ISP.
- PON flashes quickly, LOS flashes slowly - insufficient signal strength in the cable.
- Both indicators flash slowly - hardware failure.
Problems and solutions
A connection problem is indicated by a red indicator light. The LOS indicator is responsible for connecting to the provider. If the red LOS light on the router is on or blinking red, then there are problems with the Internet. Internet and telephony do not work.
On some models of routers, the LOS indicator is not provided and PON performs its function.
If the PON flashes red, it means the same thing - no internet connection.
You can try to solve this problem in the following way:
- First you need to check the integrity of the optical cable leading from the router to the outlet. It can break if you bend it badly or move furniture and crush it. Also, the cable can be damaged by pets.
- If everything is in order with the cable, check if the plug is firmly seated in the router connector. It should hold firmly, not dangle. Disconnect and reconnect the cable.
- If after these manipulations the problem does not disappear, dust may have got on the plug. This can happen if you moved the device from place to place and the cable was left unconnected for a while. Pull the plug out of the router and wipe it first with a dry cloth. If it is not possible to remove the contamination, then with an alcohol wipe. After that, reconnect the cable and check if the Internet is working.
Laser radiation, even if it is not visible to the eye, can damage the retina! Therefore, all manipulations for cleaning the fiber optic cable should be carried out with the laser radiation sources turned off on both sides and in special protective glasses.
If the indicator continues to flash red, then this is a problem on the line or on the provider's equipment.
In this regard, when working with fiber optic cables, you should pay attention to the following:
- Avoid damage and breakage of cables. Don't push it.
- When the plug is pulled out, close it with a special protective cap. These caps should be stored in an airtight container to keep them free of dust.
Thus, the LOS and PON indicators allow the user to know that in this moment happens to the ONT router and identify connection problems. The user can independently try to fix these problems if the connection failed due to problems on his side. If the problem arose on the side of the provider, you will need to contact the technical support service to solve it.
This is due to the requirements of new services and "heavy" applications that can fully function only with a PON connection from Rostelecom. That is why it was necessary to introduce fiber optic technologies that meet the requirements of high-speed Internet.
This article contains several items:

PON technology from Rostelecom
The most important advantage of this technology compared to other types of connection is the high data transfer and, as a result, the responsiveness of networks. Therefore, a PON connection is optimal for connecting large co-companies to the Internet.
Currently, Internet speed requirements reach 100 Mbps, and will approach 1 Gbps in the near future. Only optical cables can support such high performance. This is especially true for large distances, which, of course, exist between the provider and the user.
For service providers, FTTH (Fiber to the Home) bandwidth is already available, which is routed to the home. Thus, new buildings will serve as the basis of access networks and will be able to function for many years. The implementation of FTTH access networks is far from being a cheap process, which requires not only labor-intensive construction works but also significant financial costs.
However, the development of Wavelength Division Division (WDM) technology, which uses a single fiber for incoming and outgoing traffic, is to a large extent improved the situation. The first of the FTTH networks have already moved to a newer standard, where a single fiber is connected to a passive optical splitter, which in turn distributes the signal to several subscribers.
It was this standard that began to be called the PON technology, which Rostelecom is now actively using. With this technology, the network can support 1:64 signal splitting from a single fiber. In addition, Rostelecom's PON technologies allow subscribers to use without the use of IP set-top boxes.
Advantages of the Internet using PON technology from Rostelecom
The most significant advantage of PON Internet from Rostelecom is that with the help of inexpensive optical splitters, a common fiber provides a network for many users. But it should be remembered that such splitters maintain network responsiveness with up to 64 users. Thus, this technology is of interest not only to subscribers, but also to service providers who want to replace somewhat outdated copper networks.
Features of PON networks, which can also be called pluses, are:
- absence of electromagnetic interference, since there is no need to use active equipment directly in the access network;
- reduction of fiber and equipment in the central office.
Rostelecom's PON equipment provides greater throughput and supports dual distribution ratio. This means that with a 64-lane allocation, each user will get a fairly large connection bandwidth, about 35 Mbps. If the provider uses lower distribution factors, for example, 16 or 32, subscribers will receive even more bandwidth. Due to the efficient use of the bandwidth of the PON standard, subscribers are provided with a high data transfer rate. In addition, this technology makes it possible to use not only high speed internet, but also multi-services such as video, voice, data.
Which modems are suitable for connecting PON from Rostelecom
GPON technology is an industry-wide interchangeable standard. This indicates that PON modems of any manufacturer will work correctly with devices such as ONT.
This, in turn, affects the reduction in the cost of equipment and enables providers to offer subscribers the most favorable rates for services. Also, it is important to note that the updated technology based on XGPON standards increases network performance up to 10 Gbps, while maintaining backward compatibility with already deployed networks.
How to set up the equipment
As a rule, PON equipment from Rostelecom does not need to be carefully configured, since all the necessary parameters have already been entered by the provider. But in some models WiFi router with PON technology, configurations will need to be adjusted wireless network and set connection parameters. These parameters include the login and password of a PPPoE user type, which Rostelecom provides to the subscriber when concluding an agreement.
If, after correctly entering all the necessary parameters, the PON indicator on the equipment lights up red, then we recommend that you contact Rostelecom customer technical support with this problem.

Users home internet from Rostelecom, they occasionally wonder why the red light is on on the modem and what problems it can report. Failures in the operation of the router can cause significant harm, causing negative emotions from the impossibility of working or entertaining on the network. A serious breakdown of the device will lead to a complete loss of functionality and, accordingly, to. To understand the actions necessary for self-repair, you first need to find the cause of the breakdown. Experts will also be asked to report it if possible. service center when sending the device in for service.
The red light on the modem is on: possible problems
common cause possible faults may be a problem on the provider's side. Usually they are caused by scheduled work or failure of service equipment. In such situations, users will not be able to deal with the problem personally. The only thing that can be done is to wait until the operation of the devices on the provider's side is normalized.
On the Rostelecom router, the red light may be on due to the influence of factors such as:
- mechanical damage to the modem structure;
- incorrect setting or reset of all tasks;
- fluctuations in the operation of electrical networks and limited access to the Internet;
- overheating of some parts of the router (observed only for samples that have been in use for a long time and need to be replaced).
Attention! Internet users from Rostelecom who wondered why the red light is on on the router should contact support for help to find out the exact reasons and further actions.
You can call the support service by calling hotline available around the clock.
If the red light on the modem lights up after sudden voltage drops, there are two possible solutions to the situation. The most likely failure is a wiring problem. In this case, you will need a partial or complete replacement of the contact wires, which is quite problematic to do at home.
The second option is the combustion of important elements, for example, a power supply. In this case, the red light on the modem from Rostelecom may not light at all or fade slowly. The solution to this problem most often lies in the complete.
User troubleshooting flow
To achieve an effective result, it is usually necessary to carry out a number of simple operations:
- if the router is old, disconnect it from the network and wait a few minutes (the components will cool down, after which you can safely continue working);
- if a red light is on on the modem from Rostelecom, reconfiguring the device or returning to factory settings may help.
The settings are activated only after the modem is rebooted. If you performed all the operations correctly, then the green light will turn on instead of the red indicator on the router from Rostelecom. This LED indicates the correct working condition of the modem and the successful connection.
If you are afraid to re-configure yourself, do not risk it and call a specialist for help. An experienced master will find out the cause of the failure and will do necessary work with quality assurance.
The question of why the red indicator is on on the Rostelecom router has several answers. Lost settings software can be corrected using hints in the interface. Hardware failures require professional approach and replacement of parts in the structure itself. Remember that the outcome of a situation depends on its complexity. If you are not confident in your abilities and knowledge, call technical support and call the master at home.
