The JBX42086 LC/APC to SC/UPC Duplex Singlemode Fiber Patch Cable represents professional-grade networking infrastructure designed for mission-critical telecommunications and data center environments. This 75-meter cable delivers reliable, long-distance fiber signal transmission with minimal signal degradation. **Key Technical Features:** Constructed with a 9/125 singlemode core using advanced G.657.A1 glass fiber technology, this cable achieves exceptional performance specifications. The insertion loss rating of ≤0.35dB (0.15dB typical) ensures minimal signal attenuation across standard wavelengths, while return loss of ≥20dB maintains signal integrity. Attenuation performance is optimized for both 1310nm and 1550nm operating windows at 0.25dB/km and 0.35dB/km respectively. **Design & Construction:** The durable yellow OFNR (riser-rated) jacket provides excellent protection while meeting building code requirements. At just 1.8mm diameter, the cable offers space-efficient routing without compromising durability. The Type A to B crossover polarity configuration ensures optimal compatibility with duplex installations—the most common configuration for modern fiber networks. **Compliance & Standards:** Fully TAA compliant and manufactured to meet EU RoHS and ELV directives, this cable satisfies federal procurement requirements. Testing adheres to rigorous ANSI/TIA/EIA-455-171-A-2001 standards, ensuring consistent quality and performance. **Practical Advantages:** Shipped from multiple U.S. locations (California, Texas, South Carolina), qualifying orders receive free standard shipping on orders exceeding $99. The cable is available in custom lengths for specialized routing requirements. A 90-day limited warranty provides confidence in your investment. **Ideal Applications:** Perfect for campus network expansions, data center upgrades, long-distance facility connections, and telecommunications infrastructure requiring reliable, tested performance. The combination of extended 75-meter length, low insertion loss, and professional-grade construction makes this an excellent choice for budget-conscious IT departments seeking dependable fiber connectivity without premium pricing.
