Overview
Plastic-optical-fiber TOSLINK cable for S/PDIF optical digital audio transfer. Galvanically isolated by design (no electrical connection between source and sink), which makes it the easiest way to break ground-loop hum between source and DAC.
Bandwidth limit is the spec — 24-bit / 192 kHz PCM. No DSD support (DSD requires the higher-bandwidth AES/EBU or USB paths). Optical cable connectors degrade with repeated insertion: plug only as often as needed.
Useful from a streamer or computer S/PDIF optical output into a desktop DAC with optical input. The galvanic-isolation alternative to USB.
