Description
The ST/UPC–LC/UPC Duplex OS2 Single Mode Fiber Optic Patch Cable is engineered for high-speed, long-distance optical transmission across telecom networks, data centers, and enterprise-level applications. Featuring a 9/125µm OS2 single-mode fiber core, this patch cord delivers ultra-low attenuation and stable performance in demanding installations.
Equipped with ST/UPC and LC/UPC connectors, the cable ensures precise optical alignment and minimal signal loss. The 3.0mm OFNR jacket enhances flame resistance and mechanical protection, making it suitable for indoor riser-rated environments. This hybrid duplex configuration is ideal for connecting equipment with different interface types while maintaining consistent optical quality.
