LC APC to ST APC Fiber Patch Cord for OS2 Duplex Single-Mode Links

This LC APC to ST APC fiber patch cord uses OS2 9/125 μm single-mode fiber, APC-polished connectors at both ends, and a 2.0 mm LSZH jacket for compatible indoor telecom and FTTH links. Its duplex design provides two fibers for separate transmit and receive paths where supported by the connected equipment. APC end faces are designed to reduce back reflection in compatible optical connections. Use APC connectors only with compatible APC interfaces; do not mate APC and UPC end faces.

OS2 9/125 Single-Mode Fiber
