EMF Effects from Wireless, Wifi , Ethernet , Cable, Fiber Optic

Are there any hardware or software startups working on Media Converter technology described at https://www.emfanalysis.com/fiber-optics-increasing-electrical-sensitivity/ The article at link above says "The next question will be how to design media converters in the customer’s home that do not put a lot of EMI both on the data (Ethernet) and electrical systems. This will take good engineering. - (for instance GPON fiber to the home with a truly low-EMI media converter, once we find one that has been made). - Fiber can be made safe, it’s just that the current systems can have problems. What we need is pure fiber to the home (GPON) with no power backbone (no EMI) and a low-EMI media converter at the home. This would give us internet that is healthy/safe/fast/reliable for the entire society."
