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?

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.

Jitter is not additive if you have a properly designed asynchronous DAC.

Again it is the equipment design and build which is key and not the cable. Incoming jitter becomes irrelevant if you have a DAC that ignores it.
