They are one in the same.
Toslink is the cutsey name developed by Toshiba for digital audio optical connectors.
Kinda like Bayer invented the term "Asprin" which is mnow used by everyone for acetylsalicylic acid pills.
Digital Optical vs Toslink Cable
Hi There,
In answer to your question Toslink Cables and Digital Optical Cables are one and the same item. Toslink is the "technical" name for the device. From past experience i can say that if you have the choice between using a toslink cable and a digital COAXIAL cable, i would go with the coax every time. Gives you a much smoother sound, give it a try!
Happy Listening
