The JBX43008 LC/APC to LC/UPC simplex singlemode fiber patch cable represents premium optical connectivity for critical network infrastructure. This 6-meter cable combines precision engineering with practical design for professional installations. **Technical Specifications:** Built on 9/125 singlemode architecture with G.657.A1 glass fiber, delivering industry-leading performance metrics. Insertion loss measures ≤0.35dB at 0.15dB typical, while return loss exceeds 20dB for optimal signal fidelity. Attenuation specifications are verified at 1310nm (0.25dB/km) and 1550nm (0.35dB/km), meeting ANSI/TIA/EIA-455-171-A standards for fiber optic testing. **Superior Design Features:** The LC/APC connector (angled physical contact) on the transmit end pairs with LC/UPC (ultra-physical contact) on the receive end, providing optimized performance for unidirectional signal transmission. The 1.8mm outside diameter enables efficient cable management without excessive bending radius constraints. OFNR (Optical Fiber Non-conductive Riser) rated jacketing ensures safe use in vertical runs between building floors. **Professional Applications:** Ideal for data centers, telecommunications facilities, CATV networks, and enterprise environments. Single-strand simplex configuration suits applications requiring dedicated transmit or receive paths. The distinctive yellow jacket simplifies cable identification in complex installations. **Compliance & Support:** TAA compliant for government procurement. RoHS/ELV directive adherent. Manufactured in Taiwan, USA, or China with quality oversight. Includes 90-day limited warranty. Custom lengths available for specialized projects. Ships free on orders over $99 from Danville CA, Fort Worth TX, or Beaufort SC distribution centers. **Why Choose This Cable:** Precision-tested attenuation ensures reliable long-distance signal transmission. Industry-standard connectors guarantee compatibility with existing infrastructure. Riser-rated construction provides building code compliance. TAA compliance opens government and institutional markets. Competitive pricing without sacrificing quality standards.
