    Hello!
    I was informed that there will be optical fibers installed in my location.
    Will this router be able to connect to it: TP-Link TD-W8970-v3?
    I see there is a WAN input so I guess so?

    And how does a colleague want to connect an optical fiber to such a socket? I suggest you wait when your colleague gets the equipment from the operator - then you can shop. There is a good chance that a colleague from the operator will get the router.

    I would rather buy the router chosen by my colleague for ADSL services, although as it can be set up on one of the Ethernet ports, it will also be able to create a network on the link provided by the Ethernet network.

    If you do not get a router in this set (looking after the Orange offer, it could probably be Funbox 3), you will get a device to which your router should be able to connect and configure.

    It's about range, I have a big house so I need it. That's why I want to keep this router.

    And I also have a question, how would I like to use a television connected to the Internet with a fiber optic cable, then it can also be solved like this?

    As far as I know (but I do not have such a service, so these are the observations from installations seen somewhere there), you will get a decoder for TV, which must be connected with an Ethernet cable to the router from Orange. When it comes to extending the range, you can always use the tplink as a device that will create a wireless network in a different place (for example, on a different floor than the Orange router). Of course, a cable will also come in handy between these devices :)

    You will get Funbox 3 for orange services on fiber, which probably cannot be switched to bridge mode.

    I don't know, but I know that my router has a WAN input, so you can connect optical fibers to it.
    What should I do?

    Read what an optical fiber is. Once you come up with an idea how to connect a piece of glass to an electrical outlet with eight copper plates without additional conversion (and it will start working) - you will probably become a contender for some prestigious award. To this day, shining the laser into the WAN Ethernet socket does not result in any communication (although if you have a high-power laser, it may start to smoke, so you will be able to use communication from the old redskins).

    And then, after you've read it, wait patiently for what you get from Orange, because now you can speculate and theorize.

    After all, this funbox has nothing special, it will not differ from the dsl router?

    WAN stands for Wide Area Network. Nowhere does it say that it should be an optical fiber.

    But if you know better what can be connected to your router, why are you asking?

    Not every lamp box is the same. If I agree for my colleague ADSL, Ethernet and FTTH, most of these boxes do exactly the same.

    That's why I don't know why I'm asking.
    My point is that this router can be connected to fiber optics, not some funbox.
    Therefore, I am looking for a solution :)

    Do you have any solution with me?

    The router colleagues CANNOT connect to the optical fiber. You must have a fiber optic modem. A colleague from the operator will get it. It will probably also be equipped with a router (Funbox), if a colleague has a TV from Orange, it will be even difficult for a colleague to replace the operator's device with any other (but of course it will not be impossible).

    You will get a nice funbox, you will see what the range will look like. If it is too weak, you will put your router in another part of the house, or you will turn off WiFi in the operator's device (if it is possible) and, after appropriate configuration, connect your router next to the operator's device.

    I can only stay on the internet. Is it possible to connect my router to the fiber optic modem?

    Added after 3 [minutes]:

    So first goes the fiber optic modem and then the fanbox or router?
    Like now, I have a telephone socket first and then a router

    Here I see that it is possible to connect a fanbox with a router via LAN, so I think I will :D

    A colleague can connect his TPLink to a fiber optic modem or router (e.g. a funbox), but it will not always make sense (and the configurations for these devices may be different, e.g. by connecting to a funbox, you can configure a tplink as an access point).

    HMMM
    And in the fanbox there is sometimes such a thing as turning off WI-FI?
    Then I would only use mine

    I read about this funbox 3.0 and from what I found out it's not a total crap.
    It can work on 2 bands 2.5ghz and 5ghz which is a big plus.
    There are only no antennas, so does this translate into poor coverage?
    If anyone has this equipment, please review it for me.
    My main question is whether the range is good.

    It is enough for one flat in the block.
    May be too weak for a two-story house.

Topic summary

✨ The discussion revolves around the compatibility of the TP-Link TD-W8970-v3 router with an upcoming optical fiber installation. Users express concerns about connecting the router directly to optical fiber, clarifying that a fiber optic modem is necessary for such a connection. The TP-Link router can be used in conjunction with a fiber optic modem or a router provided by the ISP (e.g., Funbox 3) to extend the network range. Users also inquire about the potential to disable Wi-Fi on the Funbox to utilize only the TP-Link router for better coverage, especially in larger homes. The conversation highlights the importance of understanding the connection requirements for fiber optics and the role of additional equipment in setting up a reliable network.

FAQ

TL;DR: RJ45 uses 8 copper contacts, not fiber. "Shining the laser into the WAN Ethernet socket does not result in any communication." [Elektroda, dt1, post #16702687]

Why it matters: If you’re moving to fiber, you need the right ONT/router chain and a clean way to keep your TP-Link for Wi‑Fi coverage.

Quick Facts

Can my TP-Link TD‑W8970 v3 plug directly into a fiber socket?

No. You cannot terminate optical fiber on the TD‑W8970 v3. You need a fiber modem/ONT from the operator first. “The router CANNOT connect to the optical fiber.” Use the operator’s ONT/router, then attach your TP‑Link behind it if needed. [Elektroda, dt1, post #16702706]

Does the WAN port mean my router accepts fiber?

WAN on the TD‑W8970 v3 is an Ethernet interface, not an optical input. "WAN stands for Wide Area Network." RJ45 uses 8 copper contacts, so it won’t accept an optical patch cord. Connect Ethernet coming from an ONT instead. [Elektroda, sanfran, post #16702693]

What equipment will Orange install for FTTH?

Orange provides fiber termination and a router such as Funbox 3 for fiber services. Expect to connect your devices to the Funbox, and add your own access point if you want better Wi‑Fi coverage. [Elektroda, szwagros, post #16702559]

How do I connect my TD‑W8970 v3 behind the Funbox to extend Wi‑Fi?

Use it as an access point.
  1. Connect TD‑W8970 v3 LAN to Funbox LAN.
  2. Disable DHCP on the TP‑Link; set a fixed LAN IP in the Funbox subnet.
  3. Configure SSID/security; place it where coverage is needed. [Elektroda, dt1, post #16702739]

Can I replace the Funbox with my own router?

It’s difficult, especially with Orange TV. The operator’s device integrates required functions, and TV service expects it. Keep the Funbox as the primary router, and add your TP‑Link as an access point for coverage. [Elektroda, dt1, post #16702706]

Will Funbox 3 Wi‑Fi cover a large two‑story house?

Not by itself. Reported coverage is enough for one flat and may be too weak for a two‑story home. Plan on adding an access point or wired backhaul upstairs for consistent performance. [Elektroda, Szyszkownik Kilkujadek, post #16705775]

Does Funbox 3 support 2.4 GHz and 5 GHz Wi‑Fi?

A user report notes Funbox 3 operates on both 2.4 GHz and 5 GHz bands. Treat this as practical guidance and verify in your unit’s interface. [Elektroda, Przerwus, post #16702746]

How do I connect Orange IPTV/decoder with fiber?

You receive a TV decoder that must connect by Ethernet to the Orange router (e.g., Funbox). Place the decoder near the router or run Ethernet to the TV location. [Elektroda, dt1, post #16702540]

Can I ask Orange to install only a socket and skip their router?

Skipping operator equipment won’t work. Fiber needs an ONT/modem to convert light to Ethernet. As one expert put it, “shining the laser into the WAN Ethernet socket does not result in any communication.” [Elektroda, dt1, post #16702687]

What’s the correct connection order with fiber at home?

Typical chain: Fiber → ONT/modem → Funbox (router) → your TP‑Link as access point if needed. Your TP‑Link can connect via Ethernet to the ONT/router to extend coverage. [Elektroda, dt1, post #16702739]

Can I disable Wi‑Fi on the Funbox and use only my TP‑Link?

Yes, if the Funbox interface allows Wi‑Fi off. Then connect your TP‑Link via Ethernet and run Wi‑Fi from it only. This is a common way to improve coverage while keeping the operator router for services. [Elektroda, dt1, post #16702706]

Is there a bridge mode on Funbox 3 for Orange fiber?

Users report Funbox 3 lacks bridge mode. Plan for double NAT or configure your own router as an access point to avoid routing conflicts. This is the main edge case when integrating personal gear. [Elektroda, szwagros, post #16702559]

Can the TD‑W8970 v3 handle the fiber Internet speed?

It won’t terminate fiber, but it can distribute Ethernet from the operator gear. Use it as an access point or secondary router, connected LAN‑to‑LAN for Wi‑Fi expansion. [Elektroda, dt1, post #16702433]

What if my house is big and I need better range?

Place the TD‑W8970 v3 on another floor, connected by Ethernet to the Funbox. This wired backhaul improves coverage and stability better than relying on a single router. [Elektroda, dt1, post #16702540]
