"Gold Plated Toslink Digital Optical Audio Cable with Metal Connectors and Braided Jacket"
I've got a few from BlueJean and they have the aluminum connectors too. Just not a good idea.
Okay, you guys made me go look.
I've a couple that are plastic all the way. Thin black cable. I've a couple that are the same thin black cable, but with aluminum covers over the outer part of the ends. I've a couple that are the thin black cable and ends, but inside a silver woven techflex cover and with square finned covers over the end of aluminum. Then I have those with the black techflex cover and the round aluminum and gold plated metal ends. My motivations were to have 4 different looking ones so when I record and run things altogether I can see which is which. I've had at one time some with the thicker cover and gold plated plastic ends.
Just a side note, they've installed fiber optic internet in my area, and that is some really thin stuff. Extremely thin, but tough cover over a thin fiber. It can be bent pretty tightly and springs back like a steel spring. The whole thing maybe 1 third the thickness of these cheapest Toslink cables and able to transmit at gigabit speeds. This is what they use from the curb to the house. The main cable is fairly thick, maybe a 1/2 inch of fiber optic from Corning. I'd worked a little with some fiber optic instrumentation cable about a decade ago. It wasn't nearly as tough as this newer stuff.
