LC/UPC to ST/UPC OS2 Simplex Single-Mode Fiber Patch Cord, LSZH

What is an LC/UPC to ST/UPC OS2 simplex patch cord used for?

This patch cord is intended for a single-mode link where one endpoint requires an LC/UPC connector and the other requires ST/UPC. Both ends use UPC polish, but the connector families are different, so it works as a transition cable between LC and ST interfaces while keeping the same polish type.

Are LC/UPC and ST/UPC interchangeable because both use UPC polish?

No. UPC describes the end-face polish, while LC and ST are different physical connector formats. The LC/UPC end must connect to an LC-compatible interface and the ST/UPC end must connect to an ST-compatible interface. Matching only the polish type is not enough.

What does OS2 simplex mean on this LC/UPC to ST/UPC cable?

The current page lists OS2 9/125μm single-mode fiber and simplex construction. In this product description, OS2 identifies the single-mode fiber category and simplex describes the one-fiber cable structure. These properties are separate from the LC/ST connector choice at the two ends.

What specifications are listed for this LC/UPC to ST/UPC patch cord?

The current product page lists an LSZH jacket, available lengths from 1m to 10m, insertion loss of ≤0.5 dB, and FTTH / Telecom Network as application fields. These specifications should be reviewed together with the connector pair when selecting the cable for a link.

What should I check before ordering this LC/UPC to ST/UPC patch cord?

First confirm that one endpoint really requires LC/UPC and the other requires ST/UPC. Then choose the required cable length within the listed 1m–10m range and confirm that OS2 single-mode simplex fiber matches the intended link. The listed LSZH jacket and insertion-loss specification should also be considered before ordering.
