Hi,

On the Proximus website we can see the following install picture

full-screen
btw what a mess !

Obviously I didn’t see on their website which kind of fiber is entering in the building (1)

What are the number 2 and 3 ?
I suppose the number 3 convert the Fiber signal to another type ? SMF to MMF ?

The 5 is obviously a Fiber Media converter

“Fun fact” it is write on the number 5:

• Cet appareil fait partie de ce batiement. Veulliez ne pas le debrancher ou le deplacer.
• This device is part of this building. Please do not unplug or move it.

Do you know if a Router/modem is required after the point 5 ? If yes which protocol it use to the ISP ? PPP ?

Thanks
