Something in the fmc chain is faulty, whether it’s the cages, the receiving box, or that first piece of fiber. Try swapping boxes and see if the lights do the same thing, this can at least eliminate one possibility.

Can you switch the fiber cables. Left side to right. Etc.

I also have a multimode setup at this point I'm wondering if one of your sfps or fmcs is bad

I agree with all of the above. You can hunt down the problem by swapping things and seeing if the problem follows the swap.

Thank you all for the suggestions! This is why I love these forums! I'll report back after I try swapping/switching the boxes and cables to try and hunt down the problem.
1. If you have multimode modules, you must use multimode cables (OM3 is an aqua jacket or OM4 is an violet jacket).
Yellow cables are singlemode. You can't use a multimode transceiver on single mode fiber optical cable. Large optical loss will occur if a multimode transceiver is connected with single mode fiber.
2. Your modules are multimode dual (Duplex) so you must connect both cables. You can use single (Simplex) cables but you must connect them crosswise
In your case, you need to buy one of these cables.
If the fiber optic connection works, the green FIBER LED will light up.
The 100M LED is on properly because the R26 network card speed is only 100Mb/s

Thank you for the reply! I connected my single cables crosswise and got the FMC mod working right away! Haven't had a chance to listen to a lot of music yet, but after a quick listen the sound seems MAYBE a tad bit cleaner. There is MAYBE a little less sharpness around the edges of notes so the separation between sounds might be a bit clearer. I look forward to further listening!1.

But are you saying that it would still be better to use multimode cables instead of the single cables connected crosswise?
Hello, I have an Asus tuf ax-6000 router. I'm trying to assign a permanent ip to gustard, but after every new run gustard changes the MAC address and not all ip to mac address assignment fails. Have any of you encountered such a problem and have an idea for solving it?

Yes after the last firmware update the R26 now has randomized mac addresses I had mine on a static IP until the update. Don't know how to change it unfortunately.
I'm not crazy. Its good. But how I can have static IP on gustard? Any possibility to write it in dac?
Help needed.

No you just had the cables switched because you seperated them.
Single mode is more recommended than multi mode for less reflections.
No way unfortunately. Gustard would need to add a firmware update for this
Deleted - just read re randomised MAC addresses...

Ahh, I see. Can you recommend some single mode SFP module if I want to switch to one down the road or would any single mode SFP module be equally good?
