ISP Handoff

I've been involved in networking for a few years but am defiantly not an expert and I've never been involved with ISP/Carrier networking. I'm curious as to the application of the way that our ISP has configured the handoff / the equipment provided.

We have a dedicated fiber line with Lumen (CenturyLink) - due to our location, this is the cheapest because we are right by part of their backbone network. They have a switch that is doing the conversion from fiber to copper, that is then feeding a Lumen provided router, and then they handoff the connection and we run it into our routers.

What is the application of the ISP having both the switch and the router?

Thanks for indulging my curiosity.
