The JBX43123 2m SC/APC to SC/UPC Simplex Fiber Patch Cable represents professional-grade optical connectivity engineered for demanding telecommunications and data center environments. This cable delivers the performance, compliance, and reliability required by modern fiber infrastructure. Technical Specifications: This singlemode fiber cable utilizes a 9/125 micron core with G.657.A1 glass fiber specification, ensuring exceptional performance for both short and long-distance applications. The asymmetrical connector pairing—SC/APC (Angled Physical Contact) to SC/UPC (Ultra Physical Contact)—accommodates diverse network architectures while maintaining signal integrity. Performance Metrics: With insertion loss measured at ≤0.35dB (typical 0.15dB) and return loss ≥20dB, this cable exceeds industry standards for signal fidelity. Attenuation rates of 0.25dB/km at 1310nm and 0.35dB/km at 1550nm provide excellent transmission characteristics across standard telecommunications windows. Construction & Safety: The 1.8mm diameter yellow jacket features OFNR (Optical Fiber Non-Conductive Riser) rating, suitable for in-building vertical runs without conduit. The bright yellow color facilitates quick identification in crowded network installations. All components meet RoHS and ELV directives, with full TAA compliance for government sector procurement. Applications: Perfect for enterprise networks, ISP infrastructure, DWDM systems, telecommunications carriers, and government installations. The 2-meter length accommodates typical rack-to-patch-panel distances, while custom lengths are available for specialized deployments. Quality Assurance: Each cable undergoes rigorous attenuation testing per ANSI/TIA/EIA-455-171-A standards. Backed by a 90-day limited warranty and eligible for free standard shipping on orders exceeding $99, this cable represents a trusted solution for critical fiber network infrastructure.
