Question about AVM FRITZ!Box 4020 International

This modem is suitable for the speed of fibre optics, but does not have a fibre connection itself, have a look here: https://ch.avm.de/produkte...

Hello, depending on the provider, a converter (e.g. https://www.digitec.ch/de/s1/product/tp-link-mc220l-1x-sfp-1000base-sxlxlh-1x-rj45-1000base-t-media-konverter-netzwerk-zubehoer-2739939) including fibre optic and LAN cable should already have been delivered. Since this is not exactly my 'area of expertise', I would ask the fibre-optic provider so that the components that are still needed can be delivered later. Otherwise, a set is offered under Fiber7 hardware bundle (3m fibre-optic cable).
