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.

You might want to look at Lifatec. I have had good experience with them. 
Best regards

There is a lot of talk about quality of optical fibers but do look at the loss per meter, it is really high, on the order of 10dB or so.    Some good quality cables specify the loss and some are really very good - less than 3 dB per meter.  Other expensive cables I have found don't specify the loss/meter, so it makes me suspicious.

+1 for Lifatec. I have a couple of their cables and have used them on and off for years. Excellent quality. They easily handle 24/192, unlike plastic.

I don’t really know, but 
Lifatec
DH Labs
Wireworld
seem to be recommended the most often.

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
