The JBX42364 2.5m SC/APC to ST/UPC duplex singlemode fiber patch cable represents professional-grade optical connectivity designed for mission-critical telecommunications, data centers, and enterprise network infrastructure. This cable combines precision engineering with practical features to deliver reliable performance in demanding environments. Technical Excellence: Built with 9/125 singlemode fiber core and G.657.A1 glass fiber specifications, this cable meets ANSI/TIA/EIA-455-171-A-2001 attenuation standards. With insertion loss of ≤0.35dB (0.15dB typical) and return loss of ≥20dB, signal integrity is maintained across standard optical wavelengths of 1310nm and 1550nm. Attenuation rates of 0.25dB/km at 1310nm and 0.35dB/km at 1550nm ensure minimal performance degradation over the 2.5-meter length. Design & Durability: The 1.8mm outside diameter and OFNR riser-rated jacketing provide durability while maintaining installation flexibility. The yellow jacket serves a practical purpose—enabling rapid cable identification in congested network environments, reducing troubleshooting time and installation errors. Type A to B crossover polarity configuration represents the most common duplex patch cord standard, ensuring compatibility with existing infrastructure. Compliance & Certification: Full TAA compliance satisfies federal procurement requirements, while RoHS/ELV certification and EU Directive 2002/95/EC compliance make this cable suitable for environmentally-conscious organizations and government contracts. Harmonization code 8544.70.0000 classifies this as a premium optical accessory. Flexibility & Support: Available in custom lengths for non-standard applications, and backed by a comprehensive 90-day limited warranty. Ships from three strategic U.S. locations (Danville CA, Fort Worth TX, Beaufort SC) with free standard shipping on orders exceeding $99. This duplex fiber patch cable is ideal for telecommunications carriers, managed service providers, data center operators, and enterprises requiring reliable, standards-compliant optical connectivity solutions.
