The JBX42143 60-meter SC/APC to SC/UPC duplex fiber patch cable represents a professional-grade solution for telecommunications and data center applications requiring reliable, long-distance signal transmission. This comprehensive networking component combines precision engineering with industry compliance standards to ensure optimal performance in mission-critical environments. Key Technical Features: This duplex patch cable features dual 9/125 single-mode fiber strands with SC/APC connector on one end and SC/UPC connector on the opposite end, configured in a Type A to B crossover polarity arrangement—the industry standard for duplex patch cord applications. The cable achieves exceptional performance metrics with insertion loss of ≤0.35dB (typical 0.15dB) and return loss exceeding 20dB, meeting rigorous ANSI/TIA/EIA-455-171-A-2001 standards for attenuation testing. Performance and Materials: Constructed with G.657.A1 fiber composition, this cable offers superior bend-radius performance without compromising signal integrity. The 1.8mm outer diameter provides flexibility in routing while maintaining durability. The cable jacket is OFNR-rated (Optical Fiber Nonconductive Riser), meeting fire safety codes for building installations. The distinctive yellow jacket facilitates easy identification and management in complex network installations. Compliance and Standards: TAA (Trade Agreements Act) compliant manufacturing ensures this product meets federal procurement requirements. RoHS/ELV directives compliance guarantees environmentally responsible composition. Available custom lengths accommodate unique installation requirements. Applications: Ideal for data center interconnects, telecommunications facilities, enterprise network upgrades, and long-distance fiber runs requiring reliable single-mode transmission at 1310nm and 1550nm wavelengths. Warranty and Support: 90-day limited warranty provides peace of mind, backed by experienced technical support.
