I do not know of any analog optical coupling technology that has nearly the dynamic range of copper.
50dB is considered quite good HF dynamic range for completely sealed analog optocouplers. Start putting cables and junctions in there and it has to only get worse.

Several folks use this technology on topband. Sometimes the remote receiver is the other side of the world.

Question: Any one ever tried using light fibers as a near ultimate transmission line from their receiving antennas? 73 Bruce-K1FZ www.qsl.net/k1fz/beveragenotes.html _________________ Topband Reflector >> > _________________ Topband Reflector _________________ Topband Reflector
