I'm not following how it addresses the scenarios where the hardwire connection to the router is not possible due to location logistics.It does not.
In fact you now have two extra powered devices, the sender and the receiver for the fiber optic cable.
You still need to run the fiber optic cable so if you have problems running a hard internet line due to logistics this is not going to be any different.
However it should be better than wifi and possibly the hard internet line if you can run cable .
I guess I could as I ran a new cat7 75ft cable from my server upstairs down to a new unmanaged switch downstairs in my music room.
Could replace the internet cable run with fiber optic but I doubt I am going to try at this stage
