FC UPC to FC APC OS2 Simplex Patch Cord with Mixed-Polish FC Connectors
This FC UPC to FC APC OS2 simplex single-mode fiber patch cord has threaded FC connectors at both ends, with UPC polish on one end and APC polish on the other. It is intended for links whose respective ports require FC/UPC and FC/APC terminations; the connectors must be matched to the correct port polish. The existing product configuration specifies OS2 9/125μm single-mode fiber, simplex construction, a 2.0mm PVC jacket, available lengths of 1m–10m, and insertion loss ≤0.5 dB.

FC/UPC to FC/APC Mixed-Polish Configuration
This SKU keeps the FC connector family at both ends but changes the polish type from UPC to APC, so the two endpoints must be matched to the correct polish.
Threaded FC Connector Format
FC connectors use a threaded coupling mechanism that provides a firm mechanical connection and is common in telecom rooms, test equipment and other installations where a screw-lock interface is preferred.
OS2 Simplex, 2.0mm PVC
The working configuration uses OS2 9/125μm single-mode fiber, simplex construction, a 2.0mm PVC jacket, 1m–10m lengths, and ≤0.5 dB insertion loss.
