The JBX42634 SC/APC to LC/UPC Duplex Singlemode Fiber Patch Cable represents professional-grade connectivity designed for mission-critical network infrastructure. This 2.5-meter cable combines precision engineering with rigorous quality standards to deliver dependable performance in telecommunications, data centers, and enterprise network environments. Technical Excellence: Built with G.657.A1 glass fiber and 9/125 singlemode core specifications, this cable achieves industry-leading attenuation rates of 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm. The typical insertion loss of 0.15dB with maximum specification of 0.35dB ensures minimal signal degradation across extended fiber runs. Return loss exceeding 20dB provides superior signal fidelity critical for high-speed data transmission. Compliance & Certification: TAA compliant and RoHS/ELV certified, this cable meets stringent government and enterprise procurement requirements. OFNR riser-rated jacketing ensures fire safety compliance in building installations, while ANSI/TIA/EIA-455-171-A standards testing guarantees consistent performance metrics. Practical Design: The distinctive yellow jacket provides instant visual identification in dense cable environments, reducing installation time and troubleshooting complexity. The compact 1.8mm outside diameter enables flexible routing through tight spaces and cable trays. Type A to B crossover duplex polarity configuration accommodates standard network architectures. Flexibility & Support: Available in custom lengths for non-standard deployments, backed by a 90-day limited warranty. Ships from multiple US locations (California, Texas, South Carolina) with free standard shipping on orders exceeding $99. Applications: Ideal for connecting network switches, fiber optic terminals, and DWDM equipment. Perfect for enterprise LANs, campus networks, data center interconnects, and telecommunications infrastructure upgrades where signal quality and compliance are paramount.
