The JBX42017 30-meter LC/APC to LC/UPC duplex single mode fiber patch cable represents the pinnacle of network connectivity solutions for professional installations. This meticulously engineered cable combines precision fiber optics with robust construction to meet the demands of modern data centers, telecommunications facilities, and enterprise network environments. **Technical Excellence** Built with 9/125 singlemode fiber and G.657.A1 glass specifications, this cable delivers industry-leading performance characteristics. With insertion loss of ≤0.35dB (0.15dB typical) and return loss ≥20dB, it ensures minimal signal degradation across both 1310nm and 1550nm wavelengths. Attenuation rates of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm provide consistent, predictable performance. **Design & Construction** The duplex configuration with LC/APC to LC/UPC connectors and Type A to B crossover polarity enables simultaneous bidirectional communication. The distinctive yellow jacket facilitates quick identification in complex environments, while the streamlined 1.8mm diameter accommodates tight spaces without compromising durability. OFNR (Riser Rated) jacketing allows vertical installation without conduit, reducing installation time and costs. **Compliance & Reliability** TAA compliant certification ensures government procurement eligibility, while full RoHS/ELV compliance guarantees environmental responsibility. Manufacturing in Taiwan, US, and China locations provides supply chain resilience. Every cable undergoes rigorous ANSI/TIA/EIA-455-171-A-2001 attenuation testing, with a 90-day limited warranty backing your investment. **Applications** Ideal for data center interconnects, telecommunications networks, campus backbone installations, and CWDM/DWDM systems. Perfect for organizations requiring TAA-compliant optical infrastructure. **Shipping & Support** Ships from strategically located US warehouses (Danville CA, Fort Worth TX, Beaufort SC) with free standard shipping on orders exceeding $99. Custom lengths available upon request for specialized requirements.
