OM4 LC to ST Fiber Patch Cord — Duplex UPC Connection for LC and ST Ports
The OM4 LC to ST Fiber Patch Cord connects LC UPC and ST UPC terminations in duplex multimode fiber links. Its 50/125μm OM4 fiber and LSZH jacket suit indoor LAN patching between equipment and patch panels with the corresponding connector interfaces.
LC UPC to ST UPC Selection
The LC end and the two ST terminations serve different connector interfaces. Check the port type at each end before ordering, and maintain the required transmit-to-receive mapping across the two fibers. The extended connector boots provide strain relief; follow the installation bend-radius and handling requirements.
Standard length options are 1, 2, 3, 5 or 10 m. Choose an available option for your installation; other lengths require a separate availability check.
Match the Optical Link
40G/100G requires suitable duplex-multimode optics and a compatible channel; MPO SR4 ports cannot accept this two-fiber connector assembly directly. Verify the LC/ST termination path before selecting equipment.
