Separate the optical cable interface from the electronics in a transmitter, receiver or combination socket.
The answer
Short answer No. The cable is optical; the pins belong to the transmitter or receiver module.
The represented cable path is optical. Electrical pins shown for a transmitting or receiving module belong to that component, not to the optical cable end.
Toshiba describes a transmitter, an optical fiber and a receiver, with electronic interfaces inside the modules. A module circuit is a different reference object from the cable connector.
2Reasoning step
A combined analog/optical socket needs its own device or component documentation. Its analog terminals are not an optical pin assignment, and an optical role does not establish microphone support.
3Reasoning step
These engineering pages leave electrical contact counts unasserted and publish no terminal map. An original identification sketch is not a view from which wiring, insertion depth or fabrication tolerances can be derived.

What to check next
Identify whether the document describes a cable end, a socket or a module.
Keep component identifiers and viewing orientation attached to any electrical table.
Do not apply power or assign circuit pins from an optical identification drawing.
Question pages do not create compatibility verdicts.
They reorganize facts and uncertainty already represented in the atlas. Exact-device, cable, protocol, power, safety and performance requirements remain separate where the evidence says they are separate.

Trace 12 claims to their source records
C024A · P024
TOSLINK and Mini-TOSLINK are optical connection forms, not analog metal-contact audio interfaces.
Claim scope: Consumer identification / documented standard or product class only
Toshiba describes a digital optical path from a transmitter through fiber to a receiver, with separate electronic interfaces inside the modules. Those module interfaces are not electrical contacts on the optical cable end.
Claim scope: General optical-transmission principle only; no consumer connector dimensions, module pin numbers or voltage ratings are asserted.
Focusrite states that optical inputs on its 1st/2nd-generation Scarlett interfaces support ADAT rather than the optical S/PDIF setup described in its article; its 3rd-generation 18i8 and 18i20 instead have an optical S/PDIF mode.
Claim scope: Specified Focusrite generations and operating mode only; this difference is not a property that can be read from the optical connector shape.
For the listed interface setup, Focusrite calls for linear PCM and says its interfaces cannot decode DTS or Dolby Digital surround-encoded input. This is a receiver/decoder limitation, not a claim that an optical cable cannot carry encoded audio.
Claim scope: The article’s listed Focusrite interfaces only; no universal TOSLINK codec, sample-rate or channel-count ceiling is published.
Apple distinguishes a metal 3.5 mm analog plug from a 3.5 mm optical plug, and describes a TOSLINK miniplug adapter or optical lead for optical digital input on some Mac computers.
Claim scope: General Mac guide terminology and some-model optical input only; not proof of output support, a socket pinout or every Mac model’s capabilities.
Google explicitly lists the Chromecast Audio 3.5 mm jack as providing analog and optical digital audio output.
Claim scope: Exact Chromecast Audio specification only; no optical input, simultaneous-mode behavior or support on unrelated 3.5 mm sockets is inferred.
Apple lists digital/analog line-out support at the headphone jack of the MacBook Pro (Retina, 13-inch, Early 2015). The wording is preserved without adding a connector pin map or extending it to other models.
Claim scope: Exact Apple model and source wording only; the specification does not itself establish optical geometry, input capability or later model support.
The CLIFF FM65215, FM65220 and FM65225 table specifies different cable lengths beside a shared optical-cable photograph.
Claim scope: The photograph supports a named-series view, not identification of one exact cable-length code. The depicted tip remains capped in the original study.
Recorded evidence only. An inspection date, publisher label, source link or generated packet is not independent technical review, hardware testing, fabrication approval or a compatibility verdict.
