The JBX85067 is a professional-grade 2.5-meter LC/ST duplex singlemode fiber patch cable engineered for critical network infrastructure applications. Featuring a bright yellow riser-rated jacket that aids in easy identification and management within network installations, this cable combines durability with superior optical performance. Key Technical Specifications: This cable utilizes a 9/125 singlemode glass fiber core (G.657.A1 grade) designed to minimize chromatic dispersion and support long-distance, high-bandwidth signal transmission. The duplex configuration provides two fiber strands, enabling full-duplex communication. With LC/UPC to ST/UPC connectors in Type A to B crossover configuration, this cable is compatible with most standard network equipment and represents the most common duplex patch cord configuration. Optical Performance: Tested to rigorous ANSI/TIA/EIA-455-171-A-2001 standards, the cable delivers exceptional optical characteristics. Typical insertion loss of 0.15dB (maximum 0.35dB) and return loss exceeding 20dB ensure minimal signal degradation. Attenuation rates of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm provide excellent performance across standard telecom wavelengths. Construction and Compliance: The robust 1.8mm outside diameter jacket is riser-rated (OFNR), meeting fire safety requirements for in-building installations. The cable is RoHS compliant and adheres to EU directive 2002/95/EC, eliminating hazardous substances. Available in custom lengths for specific installation requirements, this patch cable is manufactured to consistent quality standards across multiple production facilities. Applications: Ideal for data center interconnects, enterprise LAN installations, telecommunication networks, and any singlemode fiber applications requiring reliable, high-performance signal transmission. The yellow jacket provides excellent visual identification in color-coded network environments. Warranty and Support: Backed by a 90-day limited warranty and qualified for free standard shipping on orders exceeding $99. Ships from multiple US locations (Danville CA, Fort Worth TX, Beaufort SC) for expedited delivery.
