Asus RT-BE88U

Hello everyone,

I am thinking of buying the ASUS RT-BE88U router and have a question about the SFP+ port. I want to connect it directly to my fibre optic internet connection (OTO-Dose->BE88U)

Have any of you successfully connected the SFP+ port of the RT-BE88U directly to the OTO socket using a suitable SFP+ module and fibre optic cable?

I would be particularly interested:

Which SFP+ module did you use?

Did you have to make any special settings on the router or with your ISP?

Are there any compatibility issues I should be aware of?

Any insight or experience you can share would be very helpful!

Many thanks in advance!

There are positive experiences with this router directly on 10 Gbit fibre7 connections, but these do not relate to the XGS-PON protocol of the Swisscom subscriptions offered as a shared medium, but to the AON (Active Optical Network) used by Init7 on its own pops.

For a blue Internet subscription from Swisscom on an XGS-PON connection, however, you need a different SFP+ plug-in than Init7.

This should actually work for Swisscom subscriptions:

As this XGS-PON modem has already been successfully used on a Wingo connection, it will most likely also work for blue Internet, but unfortunately I can’t test this myself due to the lack of an FTTH connection.
Of course, in addition to the VLAN ID = 10, you would also have to set DHCP option 60 on the Asus router to the correct parameters for the blue Internet.

The other cheaper and definitely workable option is of course to simply cascade the Asus router behind a Swisscom Internet box and connect its 10 Gbit WAN interface to the 10 Gbit LAN port of the Internet box.

    Werner Many thanks, Werner, for the detailed answer! It helped me a lot to understand the complexity of the different fibre optic connections.

    I was actually planning to go with the Galaxus fibre optic connection. I spoke to Galaxus support and they told me that routers that work with Swisscom or Sunrise should also be compatible with the Galaxus fibre optic connection.

    If I understand correctly, this means that if I use the XGS-PON module from Digitec that you recommended (ALL-BM410-XGS-PON-GBIC) and set the correct VLAN and DHCP options, it should also work with the Galaxus connection according to your assessment, right?

    I would be happy to hear your opinion on this.

    Thanks again for your help!

        This is to be assumed, but I have no idea what Galaxus-specific subscription settings will then be required on a third-party router.
        I don’t even know whether Galaxus already knows this itself, because this brand-new low-cost subscription is primarily intended for undemanding 0815 customers.
        I don’t know whether special requests such as a dedicated router or the availability of a public IPv4 address are even possible.

        If you decide in favour of the Galaxus subscription, my recommendation would be to start with the original router first of all, then gain some initial experience with it and only if you want more router functionalities than the Galaxus standard to cascade the Asus you want behind it in a second step and only when you are sure that you have this fully under control, then as the very last step to replace the original router with a suitable SFP+ modem.

          The values posted by @Werner are valid for Swisscom and not for other ISPs. VLAN ID10

          Each ISP has its own values.

          It is always best to first successfully connect the ISP’s router to the network. If this is running, you can try to connect another router to the network. This simply has to be certified by Swisscom.

          And if you interfere with the fibre optic connection with your router, you can call out a technician to find and fix the problem, and this could be charged.

          Greetings Lorenz

            Apparently the Galaxus support is not yet properly in the picture, a router from Swisscom does not work in the Sunrise network and vice versa as far as I know.
            In addition, only routers certified by Swisscom may be used on the XGS-PON network; Swisscom has a regularly updated list.
            Galaxus has announced that it will use Zyxel routers and, according to the above list, the AX7501 is the only Zyxel router that has been certified to date. (PM7300 is a bridge).

            I would wait and see what options the router supplied by Galaxus offers and what functions are available in the firmware.
