Single Mode Fiber Optic Patch Cable – SC/UPC to ST/APC, OS2 Simplex

Single mode fiber optic patch cable with SC/UPC and ST/APC ends, OS2 simplex fiber and a 2.0mm LSZH jacket. Both the connector format and the end-face polish differ between the two ends, so each connector must match its corresponding port.

This simplex patch cord uses OS2 9/125μm single-mode fiber with Corning ClearCurve® G.657.A1 glass, a yellow 2.0mm low-smoke zero-halogen (LSZH) jacket, and a listed insertion loss of ≤0.3 dB. Selectable lengths are 1, 2, 3, 5 and 10 m; custom lengths from 1 to 30 m are also offered.

SC/UPC to ST/APC Mixed Connector + Mixed Polish

The SC/UPC end and ST/APC end provide different connector formats and polish types in one simplex cable. Choose this configuration when one port requires SC/UPC and the other requires ST/APC.

Match Each End to the Required Port

The cable itself does not have a fixed transmission direction, but each physical end must still match the required interface: the SC/UPC end goes to the SC/UPC side of the link and the ST/APC end goes to the ST/APC side.

OS2 Simplex, 2.0mm LSZH, ≤0.3 dB

The cable uses OS2 9/125μm single-mode fiber in a simplex construction, Corning ClearCurve® G.657.A1 glass, a 2.0mm LSZH jacket, and a listed insertion loss of ≤0.3 dB.
