The JBX43370 8m SC/APC to ST/UPC Simplex Singlemode Fiber Patch Cable represents professional-grade connectivity for demanding network environments. Designed for seamless integration into existing fiber infrastructure, this cable bridges SC/APC connectors to ST/UPC connectors with precision-engineered performance specifications. **Technical Specifications:** This simplex patch cable utilizes a 9/125 singlemode glass fiber core conforming to G.657.A1 standards, ensuring compatibility with modern fiber network architectures. The cable demonstrates excellent attenuation characteristics: 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm. Insertion loss testing confirms ≤0.35dB performance (0.15dB typical), while return loss exceeds 20dB—specifications verified through ANSI/TIA/EIA-455-171-A-2001 testing protocols. **Construction & Durability:** The 1.8mm outer diameter jacketing is OFNR-rated (Optical Fiber Non-conductive Riser), making it suitable for vertical pathways and enclosed spaces within buildings. The yellow jacket aids visual identification in patch panels and cable management systems. Compliance with RoHS Directive 2002/95/EC ensures environmental responsibility and regulatory adherence. **Applications:** Ideal for telecommunications facilities, data centers, network closets, and enterprise installations where singlemode fiber transmission is required. The SC/APC-to-ST/UPC configuration supports legacy system integration while maintaining current technology standards. **Availability & Support:** Offered with 90-day limited warranty. Custom lengths available upon request. Manufactured in Taiwan, US, or China with consistent quality standards. Free standard shipping on orders exceeding $99, with fulfillment from strategically located distribution centers (Danville CA, Fort Worth TX, or Beaufort SC).
