The JBX42380 45-meter SC/APC to ST/UPC duplex singlemode fiber patch cable represents a premium solution for professional fiber optic network installations. Manufactured with rigorous quality control and tested to international standards, this cable delivers consistent, reliable performance for mission-critical applications. **Superior Fiber Optic Performance:** Constructed with 9/125 singlemode fiber and G.657.A1 glass composition, this cable provides exceptional signal integrity. The low insertion loss specification (≤0.35dB, typically 0.15dB) minimizes signal degradation over the 45-meter span. Return loss of ≥20dB ensures minimal signal reflection, critical for high-speed data transmission at 1310nm and 1550nm wavelengths. Attenuation rates of 0.25dB/km at 1310nm and 0.35dB/km at 1550nm exceed industry standards, making this cable suitable for both short-reach and long-distance applications. **Robust Construction & Safety Features:** The 1.8mm outside diameter cable features OFNR (Optical Fiber Non-conductive Riser) rating, providing fire safety compliance for installation in building risers and plenum spaces. The yellow jacket enhances visibility during installation and maintenance, reducing connection errors and facilitating faster troubleshooting. Durable plastic accessories protect connectors during handling and storage. **Professional Compliance & Standards:** TAA (Trade Agreements Act) compliance makes this cable eligible for government and federal procurement contracts. RoHS and ELV directive compliance demonstrates commitment to environmental responsibility and hazardous substance restrictions. All testing follows ANSI/TIA/EIA-455-171-A-2001 standards, ensuring measurement accuracy and product reliability. **Ideal Applications:** • Data center interconnections • Telecommunications infrastructure • Fiber-to-the-premises (FTTP) deployments • Enterprise backbone networks • Campus network installations • Telecommunications closet connections **Convenience & Flexibility:** Shipped from multiple US locations (Danville CA, Fort Worth TX, Beaufort SC) for faster delivery. Enjoy free standard shipping on orders exceeding $99. Custom lengths available to accommodate specific installation requirements.
