    Hello, I have a fiber optic connection terminated at home with a huawei echolife hg8546m router (gpon onu) and I need to move it to the attic where I have a cabinet where all the Ethernet cables connect and there will also be a gigabit switch and / or wireless router. How can I extend the optical fiber to the attic to split the signal? I mean ready-made solutions such as a fiber optic extension cable with a length of, for example, 15-20m.

    Hello, unfortunately not, in this respect I am unfortunately a layman, that's why this question is on the forum because I do not know what to do next. If it is possible to determine it after the photo, I will take a photo next weekend.

    I will be at the house at the weekend, I will do the appropriate documentation so that it can be clearly stated what is there and what can be done with it. For now, thank you for paying attention to what to look at, but I guess there are ready-made elements that will bring me closer to my goal. Regards

    According to the project, it was the destination (garage) and after interior arrangement it looks different. I do not want to combine it anymore, so I want to buy a ready-made product.

    according to the hardware specification link to the matching adapter, box and patchords

    Adapter

    I can provide exact details after obtaining information whether the optical fiber is single-mode or multi-mode.
    Additionally, consider whether it is better to contact the operator to change the place of service installation under the contract. The consequence of independent upgrades may be a malfunction of the service and then the operator may withdraw from the complaint because the actual (in the operator's documentation and systems) will be listed in the previous location and technicians are required to provide the signal and remove the failure to this place.

    You can always use a media converter and run the twisted pair cable from the router to the cabinet.

    Thank you for your answers, next weekend I will be there and I will inspect (and take photos) and in the meantime I will contact the supplier if he can provide such a service (I did not think about this option, in fact, the simplest one).

    if this router does not go where it lies, I would not touch the optical fiber, but just let the normal network cable go to the box wherever you want and that's it. and with this box a second router or switch

    Do you know what type of optical fiber do you have?

    This is not about optical fiber, because currently operators only use single-mode optical fibers. These are the connectors that have been used on both ends, that is, on the end of the optical fiber and on the side of the active device. Since you do not know what these connectors are, you need to remove both ends. You need to buy exactly the same fiber optic bundle with the length you need.

    I would opt for it too - especially since the twisted pair costs pennies.
    If you want to extend the light, there is a place for it, instead put a twisted pair in the same place.

    Hello, thank you for the idea of contacting the service provider. Will extend the cost of the material to the destination. The problem is solved, so I close it.

Topic summary

✨ The discussion revolves around extending a fiber optic connection using a Huawei Echolife HG8546M router. The user seeks to relocate the router to an attic and split the signal using a 15-20m fiber optic extension. Responses suggest using a patchcord, adapter, and box, with recommendations to identify the type of optical fiber (likely single-mode) before purchasing components. Some participants propose using a media converter and twisted pair cables as alternative solutions, emphasizing the importance of consulting the service provider for potential installation changes to avoid service disruptions.

FAQ

TL;DR: For a 15–20 m move, run Ethernet or use a matching fiber patchcord; "operators only use single-mode optical fibers." Confirm connectors or ask your ISP to relocate. This FAQ helps Huawei EchoLife HG8546M users move service safely. [Elektroda, Zutket, post #17703144]

Why it matters: You’ll avoid outages, preserve ISP support, and get a clean, gigabit-ready attic setup.

Quick Facts

What’s the best way to extend my Huawei EchoLife HG8546M connection 15–20 m?

Avoid moving fiber unless necessary. Leave the HG8546M where it is and run Ethernet to your attic cabinet. Use a gigabit switch or router there. This approach is cheaper and simpler than fiber work. Twisted pair is easy to route and terminate. [Elektroda, KOCUREK1970, post #17704728]

If I insist on extending the fiber, what parts do I need?

Use a factory-terminated patchcord, a through-coupler adapter, and a small termination box. Match fiber type and connectors to your existing ends. Avoid splicing if you lack tools. Route and secure the patchcord between floors. [Elektroda, sosarek, post #17700867]

How do I tell which fiber and connector I have?

Most FTTH runs are single‑mode. Check both ends and identify the connector types used. Remove covers and photograph the ends for reference. Then buy an identical fiber bundle at your target length. [Elektroda, Zutket, post #17703144]

Can I just buy a 15–20 m ready‑made fiber patchcord and plug it in?

Yes, if connectors match at both ends. "You need to buy exactly the same fiber optic bundle with the length you need." Keep the run protected and avoid tight bends. [Elektroda, Zutket, post #17703144]

Will my ISP help move the fiber handover point to the attic?

Contact your provider and request a relocation to your cabinet. They can extend or move the termination for a fee. This keeps service levels and support intact. One user confirmed it was done for material cost. [Elektroda, TIGIS, post #17721213]

What risks come with moving or extending fiber myself?

Unauthorized changes can break service and complicate repairs. The operator may reject complaints if you move the handover point. Technicians must deliver to the documented location. Ask for an official relocation instead. [Elektroda, Cowboy zagrabie, post #17701043]

Do I need a media converter for this setup?

You can use a media converter and then run twisted pair to the cabinet. Many users simply pull Ethernet from the router or ONT. It’s a straightforward way to reach your attic switch. [Elektroda, sosarek, post #17701056]

How should I set up the attic network once the link reaches the cabinet?

Terminate the cable in the cabinet. Connect it to a gigabit switch or a secondary router. Configure the second router as an access point if you need Wi‑Fi. [Elektroda, patgaw, post #17703087]

What ports are on the Huawei EchoLife HG8546M?

It’s a GPON ONT with 1×GbE, 3×Fast Ethernet, 1×POTS, 1×USB, and Wi‑Fi. Use the GbE port to uplink your attic switch for full speed. [Elektroda, Cowboy zagrabie, post #17701043]

How do I extend to the attic without touching fiber?

Use this simple approach:
  1. Leave the HG8546M at the current location.
  2. Run one Ethernet cable from a LAN port to the attic cabinet.
  3. Connect it to a gigabit switch or router configured as an access point. [Elektroda, KOCUREK1970, post #17704728]

What if my fiber was installed in the garage but I now want it elsewhere?

Plans change after interior work. Ask your ISP to schedule a move to your cabinet. They must deliver service to the recorded point until you request relocation. [Elektroda, Cowboy zagrabie, post #17701043]

Where can I buy the right patchcord, adapter, and box?

Purchase from fiber suppliers after confirming single‑mode and the connector types. A community member pointed to a reliable shop for patchcords. Pick the exact length you need. [Elektroda, sosarek, post #17700969]
