Endpoint map

Start with what is physically represented

The source describes mechanical optical adaptation, not certified signal direction. Resolve device output and input roles separately.

Represented path, not a complete port inventory

GOP-490 adapts a male TOSLINK optical cable to a 3.5 mm combo jack. Both represented ends stay optical; no analog path, decoder, source stage or receiver stage is supplied.

Common questions

Questions this record can help resolve

Is Mini-TOSLINK the same as a 3.5 mm headphone plug?Similar size is not a signal specification; check the exact socket’s documented role.Why can a TOSLINK cable fit an ADAT port but not produce sound?Connector fit does not select the receiver’s digital mode or supply a missing audio decoder.Does a Mini-TOSLINK adapter convert analog audio?Distinguish optical form adaptation from signal conversion and device capability.
