The JBX42061 1-meter LC/APC to SC/UPC duplex singlemode fiber patch cable represents a critical component in modern fiber optic infrastructure. This professionally-manufactured cable bridges different connector types, enabling seamless integration across diverse network equipment while maintaining signal integrity. **Technical Excellence** This cable features a precision 9/125 singlemode core constructed from G.657.A1 glass fiber—a premium specification that minimizes signal loss and optimizes performance for long-distance transmission. The duplex configuration allows simultaneous bidirectional communication over a single cable assembly. Measured insertion loss of ≤0.35dB (typical 0.15dB) ensures minimal signal degradation, while return loss exceeding 20dB provides superior signal quality and reduced reflections. **Reliability & Compliance** TAA (Trade Agreements Act) compliance makes this cable eligible for government and federal procurements. RoHS/ELV certification confirms restriction of hazardous substances, meeting environmental standards. OFNR (Optical Fiber Non-conductive Riser) jacketing rating allows installation in vertical cable runs and riser spaces, a critical requirement in multi-story buildings. **Design & Installation** The vibrant yellow jacket provides excellent visual identification in complex cable management environments, reducing installation errors and simplifying maintenance. With an outer diameter of just 1.8mm, this cable navigates tight conduits and compact installations without compromising durability. The Type A to B crossover polarity configuration is standard for duplex patch cords, ensuring compatibility with typical network setups. **Practical Advantages** Available in custom lengths beyond the standard 1-meter offering, this product adapts to specific deployment requirements. Ships from strategically located US warehouses (California, Texas, South Carolina) with free standard shipping on orders exceeding $99. The 90-day limited warranty provides peace of mind for critical network investments. **Ideal Applications** Perfect for data center interconnects, fiber-to-the-desktop (FTTD) implementations, network closet builds, and telecommunications installations requiring Type A/B crossover duplex connections. Whether upgrading legacy networks or building new infrastructure, this cable delivers professional-grade performance at competitive pricing. Every cable undergoes rigorous attenuation testing per ANSI/TIA/EIA-455-171-A standards, ensuring consistent quality and performance across all shipments.
