The JBX42129 SC/APC to SC/UPC Duplex Fiber Patch Cable represents a professional-grade solution for organizations requiring dependable single mode fiber connectivity. This 7-meter cable is specifically engineered for applications where signal quality and compliance certifications are non-negotiable. **Technical Excellence:** Featuring a 9/125 singlemode core with premium G.657.A1 glass fiber, this duplex patch cable achieves exceptional optical performance. Attenuation testing confirms performance of 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm, ensuring minimal signal degradation across the telecommunications spectrum. The insertion loss specification of ≤0.35dB (0.15dB typical) and return loss of ≥20dB demonstrates precision manufacturing and rigorous quality control. **Professional Features:** The distinctive yellow OFNR-rated jacket provides multiple advantages: immediate visual identification for network maintenance, riser-rated fire safety compliance, and UV resistance for longevity. The 1.8mm outside diameter allows for efficient pathway routing in constrained spaces without compromising durability. The duplex configuration with Type A to B crossover polarity represents industry-standard design for cross-connects and patch panel applications. **Compliance & Reliability:** TAA compliance ensures suitability for government, educational, and institutional buyers. RoHS and ELV directive compliance reflects commitment to environmental standards. Manufacturing locations in Taiwan, US, and China provide supply chain flexibility and reliability. Each cable undergoes attenuation testing per ANSI/TIA/EIA-455-171-A-2001 standards, guaranteeing consistent performance. **Applications:** Ideal for fiber-to-the-premises (FTTP) networks, data center interconnects, telecom networks, campus backbone connections, and any environment requiring single mode duplex fiber patch cords. Particularly valuable in government facilities, universities, hospitals, and large enterprises where TAA compliance and standards adherence are mandatory. **Purchasing Flexibility:** Custom lengths are available for projects with unique spatial requirements. The 90-day limited warranty provides confidence in product reliability, while free standard shipping on orders exceeding $99 improves overall project economics. Ships from multiple US locations—Danville CA, Fort Worth TX, and Beaufort SC—for efficient delivery.
