		glitchc 10 months ago \| parent \| context \| favorite \| on: Building Ultra Long Range Toslink Once you replace the TOSLINK transmitter with an SFP module, it's not the TOSLINK tx/rx that's being tested but rather the low-bandwidth S/PDIF protocol operating over a high bandwidth SFP link. So it's not really TOSLINK that's being extended but rather S/PDIF over optical fibre. Maybe I'm missing something....

TOSLINK is S/PDIF over (usually plastic) optical fiber. S/PDIF over SFP is S/PDIF over optical fiber too, unless you're using SFP DACs.
