Optical fiber, or concentration and internet quality (T-Mobile, Orange, UPC)

Question

Hello, I have a problem with the internet in my apartment. At the moment, the operator is UPC. However, the problem is not the operator, but the cable that is damaged somewhere on the way to my apartment. The internet is unstable and sometimes it disappears somewhere for days. In any case,...

You probably don't know how the DOCSIS backbone network is built. DOCSIS 3.1 Full Duplex and behind the door DOCSIS 4.0 - this is your relic.

@ Brooklyn23 do not take UPC, they offer DOCSIS technology on coaxial cable + most problems with routing, network quality is with this operator. UPC will never offer you a good concentrate upload. Concentrate should only be for TV .. ;)

Orange must let you enter the optical fiber and here you can even have symmetrical internet. There is a low ping on the optical fiber :)

UPC uses the 'fiber optic internet' service, and it is, but to the building. Nowhere does it boast of using the words FTTH only in small FTTB print. Although I know cases where UPC has an optical fiber in one block, and a coaxial cable runs to the other block from another block

And what is the impact of optical fiber or coaxial cable on ping? With the current state of technology - practically none, although it must be honestly admitted that the coaxial cable is more susceptible to interference that can disrupt the transmission, and thus increase the ping. But this is in case of failure - you have UPC and you know how many failures you had ... Ping and jitter are mainly servers and transmission structure (transmitters / receivers), not a cable like this ... And what was he supposed to say when they have FTTB technology on your building and they can't connect you to optical fiber? As for delicacy - this is talk for show, because with 1G transmissions, either through a concentration or light, both media must be handled carefully during installation. And if someone wants to do something to the cables in the corridor - he will do it anyway ...

@ Brooklyn23, I personally propose optical fiber, it is the technology of the future (Orange or T-Mobile, you have to decide for yourself). To check if T-Mobile has a different routing than Orange on the same medium (they probably use some VLAN).
In UPC I would not push myself, they use archaic DOCSIS technology, on which you will never get a good upload. The delay itself is already collected on the conversion of the fiber optic signal to the coaxial cable and then from the cable to the modem.
Ba! You even share transmission channels with your cage neighbors :)

Optical fiber is independent of other inhabitants.

Overall, UPC has strange routing

The ping overhead is due to the Docsis technology itself and even with an ideal signal it is impossible to get below 5 ms, which is real on the optical fiber. The result of the test on the T-Mobile fiber made by a user from Warsaw for the Warsaw speedtest server. In cable TV, UPC, or something similar, it is absolutely unattainable. On the UPC link, the ping looks like this: Code: text Expand Select all Copy to clipboardping 8.8.8.8 PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data. 64 bytes from 8.8.8.8: icmp_seq=1 ttl=116 time=11.4 ms 64 bytes from 8.8.8.8: icmp_seq=2 ttl=116 time=10.3 ms 64 bytes from 8.8.8.8: icmp_seq=3 ttl=116 time=14.9 ms 64 bytes from 8.8.8.8: icmp_seq=4 ttl=116 time=12.3 ms ^C --- 8.8.8.8 ping statistics --- 4 packets transmitted, 4 received, 0% packet loss, time 6ms rtt min/avg/max/mdev = 10.267/12.191/14.858/1.692 ms The fiber upload offers a much larger one, in UPC it is a maximum of 40 Mbps for a non-business customer. Routing in UPC is not bad at all.

It is purely a marketing name and, in a way, misleading customers. Orange and T-Mobile have fiber-optic internet, which can be recognized by the considerable upload and low ping, which cannot be obtained via the coaxial cable in Docsis networks at present (EuroDocscis 3.0 and Docsis 3.1). Here is a sample UPC speedtest. 1 Gbps link on the hub, upload and ping worse than in real optical fiber. If you are satisfied with UPC, submit an application and have them replace the concentrates. However, if you want to switch to a real optical fiber, you have a difficult choice because: - Orange has poor routing but gives public IP - T-Mobile does not give a public IP but has excellent routing - their services are more expensive than the link with UPC.

Optical fiber is future-proof, but it is also enough for Netflix, HBO GO and similar UPC. T-Mobile works on the Orange infrastructure, but routing has its own (separate addressing) and it is much better than that of Orange, a very important thing for players. If the lack of public IP does not bother you, take T-Mobile if you can have it at an attractive price.

In T-Mobile you can get an offer from under the counter, not the one on the website. I got 3 months for PLN 1 and from the 4th month for PLN 70. T-Mobile has its own routing, examples below: Orange: T-Mobile: Orange: T-Mobile: Orange: T-Mobile: Orange: T-Mobile: Orange: T-Mobile: I do not want to do more, but you can see immediately what has a better ping ..

m.jastrzebski · Answer

This is a cable from a box somewhere in the basement to your apartment. Installing a fiber optic from the box is neither a bad nor a good idea. It is practically irrelevant for the stability of the whole, whether in the last section, it is a fiber optic cable or a concentric or a simple twisted pair. If UPC has a network made in the building on a concentration, do not expect that they will suddenly put other devices there so that these several dozen meters will be tucked up. Because it does not make sense from a business point of view, different equipment, an additional complication for them. The Orange fiber optic has high pings not because of the type of medium, but because of the routing done around by Germany. If you are satisfied with the UPC (aside from cable failure) then take it from them.

If you don't have a reflectometer, you can actually agree with them. Ad.1. You can always put it in a strip or tube and there is no problem, as long as someone sees such a problem. But a colleague above wrote exactly what it was about - the technical structure of the UPC on the building, and it is concentric. Ad.2. It is not the optical fiber itself that is to blame, but the operator's infrastructure. There are no miracles that it would always be perfect everywhere, because if it were so, shareholders or business owners would not earn anything, and would have to invest forever ... You just have to be lucky, as with everything these days. Ad.2. You wrote that you are generally satisfied and after replacing the cable it will only get better so I would take UPC. Reason - vide] / i] point above, unless you're very lucky or need some space uploads that UPC wouldn't be able to offer you.

1. As already mentioned, it all depends on how the cable will be routed, and whether it is secured somehow. The fiber optic cable cannot be bent too much, it all depends on the type of fiber used, if it was G657 B3 it would be 5mm, and if the most ordinary fiber or G652 30mm, with smaller bends the signal could be lost.

2. I am not an orange user or not.

3. If the technicians have measured the cable with a reflectometer, they should easily know where and where the damage is. Alternatively, before making a decision, remove the existing coaxial cable and check if it is really damaged. If it's not, UPC tries to make you into a balloon.

Brooklyn23 · Answer

I can see that everyone writes in a similar way about bending the optical fiber. Naturally, if it was installed, it would have to be bent in several places at an angle of 90 degrees. Does this mean there could be interference or it could be damaged? Somehow, they install one in their homes, and there is probably always a place where they have to bend it by these 90 degrees, e.g. a corner of a room.

In fact, I don't know what they did for me. This cable is so bizarrely placed that I don't know where it branches off or where it flows into my apartment. Black comes out of the box, and in my apartment I have white in the sockets (and I have 3 sockets). It is not known where it is connected, it is not known where the entrance to the apartment is.

I do not expect. Due to the damaged cable, I have the consent of the community to run the cable from the box to my apartment along the corridor. It's about 10 meters. I asked Orange - they want to put an optical fiber. I asked UPC - and they only coaxial. It would not require any huge financial outlays. Generally, the cost is only 10m of cable, glue and technician's work. Optical fibers are connected to this box (10 m away from me) by Orange and UPC. It's just about pulling the cable from the box to me.

These high pings are in every location, in every city, or how will it happen?
Besides, what do they influence? How is it manifested?

I would prefer UPC, because as I wrote, I have no problems with them, as long as the cable transmits a signal. It's just that the community agreed for me to use the optical fiber because it is thinner, and UPC, for some reason, does not want to install it. I only have Orange left, but I have concerns about their quality.

jeaherys · Answer

Yes, the cable is a bit bent in such places, but it does not make much difference in the signal. The fiber optic subscriber cable with 1 fiber is 3mm thick and can be well masked in a self-adhesive strip. In the case of a concentration camp, it is known that the situation is completely different.

KOCUREK1970 · Answer

Another thing is a gentle arc and the derivation of 90 degrees and something else, placing a square and breaking the fiber in 90 degrees - here and here is 90 degrees. The first variant will work and the second will not, because the light at such an angle will not run (it will not bounce off the walls of the optical fiber), the optical fiber as the medium was mechanically damaged in the second case. So stick to what you already know and are satisfied. This reason is the cost of the installation site and its preparation. There are investments where UPC gives light to the apartment, but the entire investment is based on this technology. You get either an RFoG converter and a concentrator, or an ONT modem and a dedicated router. It doesn't look that simple. The optical fiber goes and enters the box in front of the block (to the basement), there is the so-called optical NOD and then, through the main cable, the signal goes to the lockbox and there is a splitter and divides the signal with a coaxial cable into apartments. In order for you to let the fiber optic cable into your apartment, you would have to convert the installations at the entrance to the block and then on - the total cost is a few thousand PLN and additionally other equipment for you as an ONT and a dedicated router. No accountant can swallow such a unit cost.

Both optical fiber and coaxial cable are specified minimum bending radii . For internal optical fibers it may be 30 ... 40mm typical, and for coaxial cable it may be 25 ... 40mm. As you can see - there is no special difference - and both require a proper approach when laying. Both types must not be exposed to any large mechanical shocks. I would say that the concentrate is even more sensitive to it than light. The Chambers' approach to both types of cables during installation may come down to a reduction in the speed and stability of the links. Of course, for low speeds it does not have to be noticeable, but with fast and ultra-fast connections - yes. However, there is a fundamental difference - EM noise immunity. Coaxial cable is ALWAYS sensitive to such interference. Optical fiber - no. Random depending on location. Big pings and packet loss are mainly problems for gaming and streaming.

And there is no tool that shows the pings of a given operator in a given location? Fortunately, they will bring me a cable, I will connect with Orange and it turns out that I will not be able to watch Netflix or HBO. Currently, when my cable makes contact, the UPC result is within 5-15.

KOCUREK1970 · Answer

They are, but you need to have internet once and be in a given location twice. Otherwise, it's like a doctor's teleportation.

Brooklyn23 · Answer

I know they are like that. I thought maybe there is some tool or website where users share this information or share measurements. Okay, then I'll have to think about what to do. UPC - some in my block, but they want to put a coaxial cable on which the community turns its nose, or Orange - uncertain and unknown, but they install optical fiber what the community likes. These uncertain pings discouraged me a bit from Orange.

KOCUREK1970 · Answer

Since it is territorial, it cannot be treated as an oracle and that it applies to all subscribers. Maybe in some typical operator forums you will find something - but here the principle is the same: one will write that a cesspool and the other that satisfied. Which one will you believe? There is no other way to check it, how to take the offer yourself and check it yourself. Anyway, it can be good for 6 months and then the meatball and problems.

Don't listen to anyone but the fiber to the router itself. Concentration is a relic that slows the net down.

Brooklyn23 · Answer

Please explain one more thing to me, because I'm getting lost.
UPC does not want to put an optical fiber from the box in the corridor - officially, because their policy is only coaxial cables and they cannot make an exception for me.
Orange, in turn, the other way - they do not want coaxial only optical fiber.
And now, if I want to change the Orange offer to UPC, this UPC internet will go on this Orange fiber, is it not possible?
And vice versa, when changing UPC to Orange (I think there is a possibility here, because Orange is ready to provide the service on the coaxial one, which I currently have damaged).

In addition, the UPC website offers only fiber-optic internet in my location. Can a pulled coaxial cable from the box to the apartment be called "fiber optic internet"?
Secondly, if they only offer optical fiber, what do I have now, since I have an old contract with them and they do not call it fiber-optic internet? They can accelerate me up to 300Mb / s so-called regular internet (PLN 45), or I can take the fiber-optic internet offer also up to 300Mb / s (for PLN 49). :roll:

Perhaps you understand how it differs?

Brooklyn23 · Answer

Well, I don't know how it is with this PING. The only thing that stops me from Orange is that I read that Orange has a large PING on the fiber in some locations. Very big, indeed. The second thing that holds me back is the delicacy of the optical fiber. A UPC technician told me that they do not install such cables for apartments due to their susceptibility to damage and that they do not want to risk constant breakdowns.

Brooklyn23 · Answer

Cable or optical fiber on PING does not matter. I mean, I'm wondering about Orange or UPC. In my case, it's just an optical fiber - Orange, a concentrator - UPC. The basic question is what has a better UPC or Orange infrastructure. The most important thing for me is not to cut Netflix, HBO GO or streaming. It looks like I will have to look for someone in the estate who has Orange and will tell me something about it. Because I can see it all depends on the location. There is no other check before signing the contract. Although using WIFI networks, I can see that 90% of residents have UPC. And I got it before that he had to say it

Brooklyn23 · Answer

And will you explain to me what myk is all about, that UPC in my block offers fiber-optic internet through a concentration? Not only UPC. The same principle is offered by: Vectra, Netia, Multimedia and some other local network. In fact, both Orange and T-Mobile offer the same. It's just that in my case, due to the damaged cable, so far these are two companies that want to pull the optical fiber directly to my apartment. Does this mean that all these operators offer something that is not really fiber-optic internet (download 300 Mb / s, upload ... 20 Mb / s)? PS: The result from T-Mobile is impressive. I wonder what district.

floriders300 · Answer

It can also be different with this replacement of the cable. If it is a development installation (cable from new in the block, plastered), the operator will not replace it, but only the building administration

Optical fiber is the future, no dummy (UPC).

Brooklyn23 · Answer

That's right. Replacing the cable is a problem because it is as you wrote. Plated, from new. You have to put a brand new one on the wall. Administrator consent is essential. There are approvals for optical fiber, because these cables are practically invisible. Thank you very much. That's exactly what I meant. I'll think about it. Due to the fact that I have several subscriptions to T-Mobile and because of the time I have endured with them, I got the lowest price on the market. Even ordinary internet from UPC or Vectra would be more expensive than fiber from T-Mobile. And the last question already. Tell me why T-Mobile has good routing and Orange is weak? I was convinced that it did not matter whether T-Mobile or Orange. T-Mobile says it works on Orange cables.

It is also worth mentioning if you take orange fiber you can get an external ont and then you can connect your own router. With Fiber from Tmobile, you won't get an external ont and you won't connect your own router, you just have to struggle with them and it's even worse than a funbox or livebox from orange.
