FIELD REFERENCE / FIBER

Recognize the end.
Verify the optical path.

A connector photograph answers only part of the question. Keep the named component, endface polish, pin state and complete path separate.

01 / IDENTITY

Which exact component?

Use a label or ordered part number. A family photograph is not a substitute.

02 / END CONDITION

Which documented interface?

Read polish, pin state and key requirements independently of body color.

03 / COMPLETE PATH

Where does the signal go?

Verify both endpoints and every intervening component before making a link claim.

The UniCam ST-compatible, Corning 722-series FC and US Conec MTP PRO studies are source-observed family examples. No exact order code is assigned to these photographs. The separate ordering rows below are not captions for the images. Neutral drawing colors do not identify polish, fiber mode or polarity. These canvases are not a common physical scale.

CONCEPTS / NOT PHYSICAL SPECIMENS

The distinctions a photograph cannot resolve.

UPC / APC / direct-mating boundary. Abstract cutaway-style endface concept, deliberately exaggerated. Two separated endfaces; no direct-mating assembly is depicted. No dimensional, wiring or compatibility approval. — Abstract explanatory diagram, not a physical specimen or engineering drawing. Inspect the concept and its source → (private workspace)

Pins / keys / optical path. Abstract text-and-symbol dependency map, not a fiber-lane map. Three separate reading panels; no physical orientation or mating face. No dimensional, wiring or compatibility approval. — Abstract explanatory diagram, not a physical specimen or engineering drawing. Inspect the concept and its source → (private workspace)

UPC/APC direct mating, unlike-ended patch cords and non-contact instrument inputs are different questions. Likewise, the MTP PRO brochure’s key convention does not supply a universal MPO fiber-lane map. No field-change procedure is provided.

FIELD OUTPUT / FOUR PAGES / SOURCE CONTEXT RETAINED

What remains unresolved?

MT-RJ has new exact-part evidence but no new physical study. LC and SC retain their inherited illustrations. No exact ordered physical part is delivered in this release. The detailed MTP PRO AEN-2102 document was not accessible without a contact form; it has not been reviewed, and no personal information was submitted.

Ten canonical claims and four new source records deepen six existing forms. Six auxiliary observations include revisits to the FC and optical-safety sources. Manufacturer drawings and photographs are not redistributed. All original studies await independent technical and rights review.
