The JBX42747 ST/APC to LC/UPC duplex fiber patch cable represents a premium solution for professionals requiring reliable, long-distance fiber connectivity. This 80-meter cable combines superior optical performance with robust construction, making it ideal for enterprise networks, data centers, telecommunications facilities, and campus backbone installations. Optical Performance & Specifications: With a 9/125 singlemode fiber core and G.657.A1 glass fiber composition, this cable delivers exceptional performance across standard telecommunications wavelengths. The insertion loss specification of ≤0.35dB (0.15dB typical) and return loss of ≥20dB ensure minimal signal degradation. Attenuation ratings of 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm comply with ANSI/TIA/EIA testing standards, guaranteeing predictable performance in your network infrastructure. Connector Architecture: The ST/APC to LC/UPC duplex configuration provides Type A to B crossover polarity, the most common duplex patch cord arrangement. This asymmetrical connector pairing allows seamless integration with existing infrastructure while maintaining signal integrity across multiple connection points. Physical Design & Compliance: The yellow outer jacket provides immediate visual identification in cable trays and patch panels while meeting OFNR (riser-rated) specifications for building-wide installations. The compact 1.8mm outside diameter facilitates efficient cable management without sacrificing durability. TAA compliance and RoHS/ELV certification ensure regulatory adherence for government and enterprise procurement requirements. Versatility & Customization: While this cable comes in an 80-meter configuration, custom lengths are available to match your specific installation requirements, reducing waste and simplifying inventory management. Shipped from multiple U.S. locations (Danville, CA; Fort Worth, TX; Beaufort, SC), order fulfillment is swift with free standard shipping on orders exceeding $99. Application Suitability: Perfect for connecting telecommunications equipment, establishing campus backbone links, or running horizontal cabling through larger facilities. The duplex configuration supports bidirectional communication, making it ideal for applications requiring simultaneous transmission and reception. Warranty & Support: Backed by a 90-day limited warranty, this professional-grade cable provides peace of mind for critical installations. All materials and construction meet industry standards for longevity and reliability.
