Optical Conversion Not Working, Please Help

Like the title says I’m having some trouble with my optical setup. I just got the last gadgets last night and hooked everything up this morning. I’m not sure where I’ve gone wrong and hoping to find some guidance. Here are the items I ordered. 






I’m using Audioquest Cinnamon Ethernet cable on each side. This was a used purchase so I don’t know for certain if they work or not.  

The converter on the router sides light indicators have the 1000m, TP, and power lit up. The TP light is solid not flashing. The manual states network connecting for solid and data transmitting for a flashing light. The converter on the r26 side shows the same thing except the 100m light is lit instead of the 1000m. 

It seems that my optical connection is where the problem is. I’m just not sure if I ordered incompatible items or if maybe one of them is faulty. I guess there’s the possibility that I hooked things up wrong but it seems pretty straightforward in that regard. Hopefully you guys can get me straightened out. I was really juiced to hook everything up this morning and hear what the fuss was about, but then nothing.






Someone with more knowledge will hopefully provide a suggestion in regards to the FMCs. Ironically, I did a deep dive on optical last night. I found threads from WhatsBestForum (here, here, and here) pretty helpful, as well as some from Audiophile Style.

I think the question I have as a follow-up for the community is whether or not that "active" optical cable may also be causing an issue - I candidly don’t know, but I vaguely remember reading this as an issue in one of the threads above.

Like you, I’m still learning while regurgitating some of the information I had been reading last night. I'm pretty confident more members will contribute to help figure this out. As a side note, I've found one of the easier paths is looking at Small Green Computer's solutions, which can be found here and here

I would have stuck with something simpler, that has the media converter built in. Keep in mind that 100 MBits is overkill for any streaming of audio or video. 1 Gbit (1000 Mbits) is overkill x 10.

A 192k/24 bit stereo signal is barley 10 Mbits.  A 4K video stream requires around 50 Mbits or less, depending.

So, a 1 Gbit/s cable can carry 20 4k video streams at once.

Maybe that can help you pick out a better integrated adapter and cable such as:



Try a different Toslink cable. The one I got from Blue Jeans does not work in half of devices I've tried.

Make sure that the you are using the proper optical cable. Then make sure you are suing the proper and identical SFP modules compatible with that cable on both ends of the cable. Then reboot your network so your router sees these connections and assigns the proper IP addresses.

Take a look at what these guys sell. Not too expensive and it works great. I have a few OpticalRendu's using their accessories.
