A 3.5 mm TRS plug has three conductive sections: tip, ring and sleeve.
Claim scope: Consumer identification / documented standard or product class only

C019B · P019
Neutrik identifies NTP3RC as a three-pole 3.5 mm male audio plug with solder termination; its customer drawing shows the plug axis at a right angle to the cable exit.
Claim scope: Exact NTP3RC component role and exterior; no channel mapping or device compatibility.

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
Source links: S845 · Evidence trail → (private workspace)
C024B · P024
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.
Source links: S405 · Evidence trail → (private workspace)
C024C · P024
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.
Source links: S409 · Evidence trail → (private workspace)
C024D · P024
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.

C025D · P025
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.

Hosa describes GOP-490 as adapting a male TOSLINK optical cable to a 3.5 mm combo jack, with TOSLINK and Mini-TOSLINK connector labels.

C025F · P025
CLIFF distinguishes the FM65010 3.5 mm optical-jack adaptor from the separately listed FM65215 mixed-ended optical cable.

C025G · P025
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.

StarTech.com documents THINTOSMIN6 as a 6 ft / 1.8 m optical S/PDIF cable with a TOSLINK male end and a Mini-TOSLINK male end; the exact product evidence does not establish every device or optical-audio format.
Claim scope: Exact THINTOSMIN6 endpoint, optical S/PDIF use and length only.

C332A · P332
Hosa GOP-490 is an optical form adapter for a male TOSLINK cable and a 3.5 mm combo jack. The documented path stays optical; analog conversion, codec decoding and compatibility with an arbitrary socket are not established.
