LC/UPC to LC/APC Single Mode Fiber Patch Cable

Enhance your network with our LC/UPC to LC/APC duplex OS2 single-mode fiber patch cable, designed for seamless, low-loss connectivity between flat-polish (UPC) and angled-polish (APC) LC ports. This duplex jumper features two 9/125μm single-mode fibers in one jacket, ensuring high-bandwidth, long-reach performance with ultra-low back-reflection. Ideal for DWDM, telecom, and FTTH applications requiring mixed polish interfaces, this cable delivers superior signal integrity and high-density compatibility. The LC snap-in plugs with 1.25mm ferrules maximize port density for patch panels, SFP, and XFP optics, while precision-polished end-faces verified with 3D interferometry guarantee optimal performance.

Key Features

  • OS2 single-mode fiber (9/125μm) engineered for long-reach, high-bandwidth circuits
  • Duplex construction: Two fibers in one jacket for simultaneous transmit/receive channels
  • Mixed UPC/APC polarity: Ultra-polish UPC on one end, 8° angled APC on the other
  • LC snap-in plugs with 1.25mm ferrules maximize port density
  • Precision geometry: End-faces verified with 3D interferometry
  • Low insertion loss: ≤0.15 dB typical, ≤0.30 dB maximum
  • Ultra-low back reflection for optimal signal integrity
  • Plug-and-play compatibility: Fits any standard LC receptacle
  • No field termination required for easy installation
  • UL-listed (US/Canada) and RoHS-compliant for safety and environmental standards
  • High-density environments: Compact LC connectors ideal for space-constrained installations
  • Professional-grade construction for demanding applications
  • Available in custom lengths, jackets, and colors to match your documentation
  • Perfect for cross-connecting equipment with mixed polish types

Ideal Applications

  • Cross-connecting DWDM equipment in telecom networks
  • Patching line cards with mixed UPC/APC polish types
  • Extending angled OLT ports to flat SFP modules
  • High-density data centers requiring compact LC single-mode connectivity
  • FTTH (Fiber-to-the-Home) installations
  • Long-distance telecommunications
  • Enterprise network backbones
