The JBX42647 SC/APC to LC/UPC Duplex Singlemode Fiber Patch Cable represents enterprise-grade connectivity for mission-critical network infrastructure. Engineered for environments where signal integrity and reliability cannot be compromised, this 30-meter cable combines superior performance specifications with practical design features. Technical Excellence: Constructed with 9/125 singlemode fiber featuring G.657.A1 specifications, this cable delivers industry-leading performance. The measured insertion loss of ≤0.35dB at typical 0.15dB ensures minimal signal degradation over the 30-meter span, while return loss ≥20dB maintains signal quality throughout your network. Attenuation testing follows ANSI/TIA/EIA-455-171-A standards, guaranteeing consistent performance at both 1310nm and 1550nm wavelengths. Design Features: The duplex configuration enables simultaneous bidirectional communication, streamlining installations and reducing cable counts. SC/APC connectors provide superior return loss characteristics, while LC/UPC connectors ensure compatibility with modern network equipment. Type A to B crossover polarity represents the industry standard for duplex patch cords, simplifying deployment. The bright yellow jacket provides instant visual identification for network technicians, reducing troubleshooting time and preventing costly misdirections. Compliance & Durability: Full TAA compliance meets U.S. government procurement requirements. RoHS/ELV directive adherence ensures environmental responsibility. The riser-rated (OFNR) jacketing safely handles pathway installations beyond simple horizontal runs, while the 1.8mm outer diameter accommodates tight routing and conduit applications. Practical Advantages: Available in custom lengths for specific requirements, this product ships from multiple U.S. locations ensuring rapid delivery. The 90-day limited warranty provides protection for your investment. Free standard shipping on orders exceeding $99 reduces total cost of ownership. Applications: Ideal for telecommunications closets, data center interconnects, fiber backbone networks, and enterprise WAN installations where performance reliability directly impacts business continuity.
