Arseni Mourzenko Asks: What are those weird wires in the audio cables?
Trying to repair a headset cable, I discovered that it doesn't look at all like the “ordinary” cables I used to repair. I was expecting to see, inside the cable jacket, four wires, each one in a wire insulation. Instead, there is:
I would imagine that the semi-transparent fibers conduct electricity, but I don't get any conductance with a multimeter, including when I try to scratch the surface of those fibers. What are they? And what is the magic which happens inside the audio cables?
Trying to repair a headset cable, I discovered that it doesn't look at all like the “ordinary” cables I used to repair. I was expecting to see, inside the cable jacket, four wires, each one in a wire insulation. Instead, there is:
- A wire with a white wire insulation.
- A sort of an orange/gold thread.
- Something which looks like semi-transparent, very narrow optical fiber, with red, green, or blue thread around it.
