Who is going to be the first manufacturer to make a Fibre Optic purifier?

Fiber Optic not LAN filters!

@jjss49 - I had the Gigafoil v4 a couple of years ago, then tried Network Acoustics (transformer based isolation) filters, and finally moved to a Sonore streamer, optical modules, and fiber.  DJM has this newer streaming-specific filter (link) but I cannot tell from the write-up whether it has an optical component like their Gigafoil v4.

sorry, but what is the need for a fiber optic filter?  I understand the purpose of isolation of copper based data transfer via USB and ethernet through a transceiver into fiber.  

Op are you taking about Fresnel reflection in fiber optics when transmitting signal via light?  Or you are still talking about Ethernet purification via fiber optics?
