Are there differing qualities of optical cable?


I currently have my Gungnir Multibit DAC connected by optical cable to my Oppo player which I use as a transport. I also have a Cardas coax cable connected to a different input.  The optical sounds better. My question is, are there different qualities of optical cable you can use, or is one the same as the other?

@rvpiano  Any reason why you didn't try the DH Labs Glass Master Toslink? Might have been an interesting comparison between house cables (vs. your DH Labs Silver Sonic coax cable).
I got the glass cable before I heard of DH Labs or I would have.
(Still can I guess.)
I'm using one for the digital audio out from my tv to my DAC. 

My previous one was from Monoprice and the DH Labs outperformed it.

I haven't done any comparisons between different brands or in your case: what I was hoping, i.e. the same brand but different digital cable types.

Digital cables or Toslink do add jitter, so getting good ones will help. Add as little as possible.

I also thought that the best glass cable was the ticket, until I discovered a really outstanding plastic cable. I even use a 15-footer of this from my Smart TV to my SS processor:

Whatever type of optical you use, try a drop of the "indexing gel" with it as it couples the optical fibre end to the internal receiver minimising any refection, thus reducing jitter.
