Optical Cable recommendations

Does anyone have any optical cable recommendations?
I want to pull the stream from my Blusound Node 2i into my Schiit Gugnier DAC just for giggles. 
I was told by someone at a cable company that most of the glass cables are made by only a couple manufacturers and not much real difference among them. Makes me wonder about some of the expensive optical cables I've seen.  I've tried plastic Tosslink in the last and it didn't cut it. 
Thanks in advance.

Very good inexpensive glass Toslink, I use:

Same, the best I have used has been the Wadia optional extra AT&T glass (not plastic) optical cable, but that used a bnc type connection it is the highest quality optical I've used.
And much better again I also used it with very expensive Indexing Gel on each end to rid any air pockets and to give clean mating surface to both. receiver and sender.  https://ibb.co/DWHx8nd

I have used different Optical cable from different manufacturers, price ranges, and could never discern a difference.  As with everything, ymmv

Liatec optical cables are an easy recommend. Good quality glass (470 strands) at reasonable prices.

It's not your question, but I think the coaxial digital output sounds better on the Node 2i.
The basic blue jeans 1694a digital cable sounds better to me than the sonic wave and Lifatec optical cables I own.

That loss seems unusually high....
