Scoped support: Apple distinguishes metal 3.5 mm analog plugs from 3.5 mm optical plugs and describes optical input on some Mac computers only.
Not established / limitations: General guide, not an exact-model optical port inventory. Optical input on some Macs must not be treated as output support or as support on every headphone socket.

Scoped support: Only those dated item rows and the shared FM652xx photograph. The photograph does not identify a cable length. Caps obscure the optical ends. Ambiguous numerical aperture and material units are not imported.
Not established / limitations: Only those dated item rows and the shared FM652xx photograph. The photograph does not identify a cable length. Caps obscure the optical ends. Ambiguous numerical aperture and material units are not imported.
Locator: Issue 5, copyright 09/2023; PDF pp.1–2: FM65010 adaptor and FM65215/20/25 mixed-ended optical cables. Only p.2 photograph visually inspected.
CLIFF Electronic Components · Unclassified publisher domain · inspected 2026-10-21 · due 2027-01-19
Within inspection window
Scoped support: The manufacturer explicitly describes the rectangular and3.5mm mini forms as optical. No analog-to-optical conversion or universal audio-format ceiling follows.
Not established / limitations: Product-family optical identification only. The3.5mm similarity warning is editorial caution, not measured user confusion. No dimensional tolerances or source photos were imported.

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
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.
Source links: S409 · Evidence trail → (private workspace)
C024E · P024
CLIFF lists FM65215 as a cable with a TOSLINK end and a 3.5 mm optical-jack end.
Claim scope: The listed optical cable only. This is not evidence of analog-to-digital, electrical-to-optical or codec conversion.
Source links: S533 · Evidence trail → (private workspace)
C025A · P025
Mini-TOSLINK uses a 3.5 mm optical form that can be confused with analog audio connectors.
Claim scope: Consumer identification / documented standard or product class only
Source links: S845 · Evidence trail → (private workspace)
C025B · P025
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.
Source links: S406 · Evidence trail → (private workspace)
C025C · P025
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.
Source links: S408 · Evidence trail → (private workspace)
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.
Claim scope: Exact Apple model and source wording only; the specification does not itself establish optical geometry, input capability or later model support.
Source links: S407 · Evidence trail → (private workspace)
C025E · P025
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.
Claim scope: Named optical adapter as a connector-form example only; not evidence that a generic analog headphone jack acquires optical support.
Source links: S410 · Evidence trail → (private workspace)
C025F · P025
CLIFF distinguishes the FM65010 3.5 mm optical-jack adaptor from the separately listed FM65215 mixed-ended optical cable.
Claim scope: Those item identities, not universal compatibility with every 3.5 mm socket. The exact FM65010 image was not visually inspected.
Source links: S533 · Evidence trail → (private workspace)
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.
