The JBX90198 is a professional-grade 35-meter singlemode fiber optic patch cable engineered for mission-critical network installations. This duplex cable combines SC/UPC and ST/UPC connectors, making it ideal for cross-connecting equipment in data centers, telecommunications facilities, and enterprise networks where singlemode fiber is required. Superior Performance Specifications: Built with 9/125 singlemode core fiber and G.657.A1 glass composition, this cable delivers exceptional optical performance. Attenuation levels reach only 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm, while insertion loss remains at ≤0.35dB (0.15dB typical). Return loss exceeds 20dB, ensuring signal integrity across long distances. All performance testing complies with ANSI/TIA/EIA-455-171-A standards. Design and Durability: The 1.8mm outside diameter with OFNR riser-rated jacketing provides excellent flexibility while meeting fire code requirements for indoor use. The distinctive pink jacket offers superior cable tracing and identification in crowded cable trays and patch panels, reducing installation errors and maintenance time. Compliance and Certification: Fully TAA-compliant and RoHS-certified per EU Directive 2002/95/EC, this cable meets government procurement standards and environmental regulations. The Type A to B crossover polarity configuration is the industry standard for duplex patch applications. Flexibility and Availability: Available in custom lengths for specialized applications, this cable comes with a 90-day limited warranty. Ships from strategically located U.S. facilities (Danville CA, Fort Worth TX, Beaufort SC), with free standard shipping on orders exceeding $99. Ideal Applications: Data center interconnections, telecommunications networks, enterprise fiber backbones, laboratory testing, and any application requiring reliable, long-distance singlemode fiber connectivity with SC/ST connector compatibility.
