The JBX42073 12-meter LC/APC to SC/UPC duplex singlemode fiber patch cable represents a professional-grade solution for organizations requiring reliable, high-performance fiber optic connectivity. This cable seamlessly bridges LC/APC and SC/UPC connector types using Type A to B crossover polarity configuration—the industry standard for duplex patch cords. **Technical Excellence** Built with 9/125 singlemode fiber core and G.657.A1 glass fiber, this cable delivers exceptional optical performance. The insertion loss specification of ≤0.35dB (0.15dB typical) ensures minimal signal degradation, while return loss exceeding 20dB prevents signal reflection issues. Attenuation ratings of 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm meet ANSI/TIA/EIA-455-171-A standards, guaranteeing consistent performance across critical wavelengths. **Durability and Compliance** The 1.8mm outside diameter provides robust protection while maintaining manageable routing through cable trays and conduit. OFNR riser-rated jacketing ensures compliance with commercial building fire codes. TAA compliance certification qualifies this cable for government procurement, making it suitable for federal, state, and municipal network projects. RoHS/ELV directives confirm environmental responsibility. **Practical Features** The distinctive yellow jacket aids in network organization and rapid identification. The 12-meter length suits most equipment room configurations, while custom lengths are available for specialized installations. Duplex construction enables simultaneous bidirectional communication, essential for modern telecommunications protocols. **Applications** Ideal for data centers, telecommunications facilities, campus networks, and enterprise infrastructure upgrades. Perfect for connecting network equipment requiring LC/APC to SC/UPC bridging. Multi-warehouse availability (California, Texas, South Carolina) enables fast, cost-effective shipping. Standard orders over $99 qualify for free shipping. **Warranty and Support** Backed by a 90-day limited warranty, ensuring confidence in quality and reliability for critical network installations.
