The JBX42441 50-meter FC/APC to FC/UPC duplex singlemode fiber patch cable represents professional-grade connectivity for critical telecommunications infrastructure. This cable is engineered to meet ANSI/TIA/EIA-455-171-A-2001 standards for attenuation testing, ensuring reliable performance in both 1310nm and 1550nm wavelengths with attenuation rates of 0.25dB/km and 0.35dB/km respectively. Key Features: • 50-meter length ideal for medium-distance runs • Duplex configuration supporting simultaneous bidirectional communication • 9/125 singlemode fiber core for long-distance, high-bandwidth transmission • Low insertion loss (≤0.35dB typical 0.15dB) minimizes signal degradation • High return loss (≥20dB) reduces signal reflection • G.657.A1 glass fiber for optimal performance and compatibility Technical Specifications: The cable features FC/APC (Angled Physical Contact) to FC/UPC (Ultra Physical Contact) connectivity, accommodating mixed-connector network environments. The 1.8mm outer diameter provides excellent flexibility while maintaining structural integrity. OFNR (Optical Fiber Non-conductive Riser) rating qualifies this cable for installation in vertical pathways and spaces between floors. Compliance & Quality: TAA (Trade Agreements Act) compliant, ensuring eligibility for government procurement. RoHS/ELV directive compliance confirms environmental responsibility. The cable undergoes rigorous attenuation testing and arrives with a 90-day limited warranty. Applications: Ideal for data centers, telecommunications networks, enterprise IT infrastructure, and any application requiring reliable singlemode fiber connectivity. The yellow jacketing provides superior visibility for cable management and troubleshooting. Customization Available: For non-standard lengths or specific requirements, custom options are available to meet your exact specifications. Shipping & Support: Ships from strategically located US distribution centers (Danville CA, Fort Worth TX, Beaufort SC) with free standard shipping on orders exceeding $99.
