SC UPC to ST UPC Fiber Patch Cord, OS2 Single Mode Simplex, 2.0mm LSZH
SC UPC to ST UPC fiber patch cord with OS2 9/125µm simplex single-mode fiber, 2.0mm yellow LSZH jacket, and 1–10m lengths.
SC UPC to ST UPC Fiber Patch Cord for OS2 Simplex Connections
This SC UPC to ST UPC fiber patch cord connects an SC/UPC port to an ST/UPC port on an OS2 single-mode link. It uses one fiber with UPC-polished connectors at both ends, making it suitable for patch panels, media converters and other equipment with matching SC and ST interfaces.
The yellow 2.0mm LSZH-jacketed cable is offered in 1m, 2m, 3m, 5m and 10m lengths. Check the connector type and polishing at both endpoints before ordering. SC/UPC and ST/UPC use different connector locking mechanisms, so each end must connect to its matching interface.

UPC Polish at Both Ends
Both connectors use UPC-style end faces. Keep mating connector polish compatible; do not directly mate a UPC end face to APC.
