The JBX43470 FC/APC to FC/APC simplex singlemode fiber patch cable represents professional-grade connectivity for mission-critical fiber optic networks. This 45-meter cable is engineered to exacting standards for telecommunications, data centers, and enterprise network environments where signal quality and reliability are non-negotiable. Key Technical Specifications: This simplex configuration carries single-strand transmission through a precisely manufactured 9/125 micron core using G.657.A1 grade glass fiber. Attenuation measurements comply with ANSI/TIA/EIA-455-171-A-2001 standards, achieving 0.25 dB/km at 1310nm or 0.35 dB/km at 1550nm. The cable maintains insertion loss at ≤0.35dB with typical performance of 0.15dB, while return loss exceeds 20dB for optimal signal fidelity. Construction and Compliance: The 1.8mm outside diameter cable features OFNR (Optical Fiber Nonconductive Riser) rated jacketing, making it suitable for vertical runs in multi-story buildings while maintaining fire safety standards. RoHS/ELV compliant and TAA certified, this cable meets stringent government procurement requirements. The protective plastic accessory construction with yellow identification jacket simplifies network management and troubleshooting. Applications and Use Cases: Ideal for connecting optical network terminals, multiplexers, and transceivers in long-distance telecommunications links. Commonly deployed in carrier-grade networks, university research facilities, and enterprise backbone infrastructure. The straight-through polarity configuration ensures compatibility with standard FC/APC connector pairs without signal reversal. Customization and Availability: Available in custom lengths beyond the standard 45 meters to accommodate unique installation requirements. Shipped from multiple U.S. distribution centers (Danville CA, Fort Worth TX, Beaufort SC) with free standard shipping on orders exceeding $99. Backed by a 90-day limited warranty ensuring peace of mind for your critical network infrastructure investment.
