Ethet net to fiber optic to feed your streamer

You might want to try a full-length CAT6 Ethernet cable without any fiber optics. You may find there’s a big difference in signal quality (not necessarily sound quality) between wifi and ethernet. There are a few major reasons to use fiber: security (it can’t be tapped), reduce RFI, run a signal via cable in excess of the twisted pair cable limit (about 300 feet). I’ve never heard of wifi signals interfering with wired ethernet, so a good old fashioned cable could be an inexpensive solution. BTW - There shouldn’t be any difference between a clean wifi, ethernet, or fiber optic signal. They all carry the exact same digital code, with error correction. (However, many on this forum disagree.)

oops, Brilliant Corners is the column, not Minds.

I am also using an LHY FMC into my Eversolo T8.  It replaced the ethernet cable that previously fed the streamer through an English Electric Ee1 filter.  I experienced a slight improvement in SQ but nothing earth shattering. 

Stan,

I think your idea to place fiber between the wireless router and streamer is good.  I have tried many SFP's and devices to capture the fiber.  Keep in mind that it can good or bad depending on implementation.  Essentially everything matters from the Ethernet cables on either side, the FMC's, the SFP's, the fiber, the power supply's and electrical quality to the power supplies.

Currently single mode fiber seems to be preferred but in my system I like the Sonore SystemOptique with the upgraded OM4 multimode fiber and Finisar SFP's.  I tried the standard Sonore FMC's with their regular SFP's and use a pair of LHY 5 volt LPS's, and found the SystemOptique much better.

I have fiber in three locations in my system.

I have the Sonore FMC's between my modem and gateway router.  I also have an OpticalModule on a non-gateway router going to a switch with a SFP port then to my streamer, there is a very big improvement over Ethernet (all my Ethernet cables are SOtM dcbl-cat7 or cat7u).

I also have fiber between my streamer and DAC via another OpticalModule and SignatureRendu SE Deluxe.

It makes sense to start simple but realize there is lots to gain from tweaks.

I recently got advice from Adrian at Sonore about using longer fiber cables (10M or longer) for better sound with multimode.  Essentially a little bit of attenuation helps the SFP's as the system was built to go several hundred meters for data systems and the signal is a bit intense over very short distances.
