I’ll go out on a limb here and say there’s even differences between Toslink cables.
Absolutely there are, not the least of which is mentioned in the post above by
@airdronian in the form of actual borosilicate glass fibers rather than plastic ones. There is no question this kind of Toslink cable actually sounds better, but it's also at least somewhat fragile and needs to be treated more carefully compared to a plastic fiber optic cable. It's also far more expensive, though the Supernova 7 referred to above (great cable) is quite reasonable compared to the stupid $499 ask for the similar glass Toslink offering from AudioQuest.
Many years ago I came across
Lifatec USA, a division of LiFaTeC GmbH based in Germany, I forget who originally turned me on to them.
At that time they did not market glass cables for the audio industry, they were purely supplying the medical and industrial sectors, though if you called them they would take a special order for one of their cables with Toslink and/or MiniPlug connectors. They would even do special orders for cables with Toslink on one end, and an ST connector on the other, as certain disc transports with ST output are actually compatible with the Toslink input on a DAC.
Fast forward to now and Lifatec USA have direct ordering from their ecommerce platform, with payment via PayPal, and their web page clearly markets the cables for use in Toslink connected audio systems. These cables are hand terminated in Syracuse NY, and feature precision machined connectors on a bundle of 470 high-grade German glass fibers. No middle man dealer or distributor mark-up.
I can't recommend these glass Toslink cables highly enough, especially since there are almost no other high quality glass Toslink cables available at all, let alone ones offered with a MiniPlug (the Wireworld Supernova 7 above being a notable exception).
I also have a couple of now discontinued Amphenol glass Toslink cables which I suspect were made by Lifatec, however those were only ever offered with standard Toslink connectors (ditto the AudioQuest until very recently) and so require an adapter for use with the 3.5mm sized MiniPlug optical ports on Chromecast Audio, Airport Express, Mac computers, and various PCs including Sony Vaio.
Sadly, the sonic end results will vary based on whether or not the partnering equipment actually uses genuine 15Mbps Toshiba optical modules. Many manufacturers cut that corner and use cheap knock-off Chinese optical modules in their equipment, which is what gives Toslink an unwarranted bad name. You can only easily tell which manufacturers aren't cutting that corner by their transmission specs, if they say their Toslink port is capable of 24-bit/192kHz (or even 24/96) that is a clear indication they are using the real McCoy.
