The JBX88103 SC/ST Duplex Singlemode Fiber Patch Cable represents a professional-grade solution for telecommunications, data center, and enterprise network infrastructure. Manufactured with precision to exacting industry standards, this 12-meter cable delivers consistent, reliable performance in mission-critical applications. Technical Specifications: This duplex configuration features two SC/UPC to ST/UPC connectors in a Type A to B crossover polarity arrangement—the most common configuration for duplex patch cords. The 9/125 singlemode core with G.657.A1 glass fiber ensures minimal signal loss and maximum compatibility with existing telecommunications infrastructure. The cable supports both 1310nm and 1550nm wavelengths, making it suitable for diverse fiber optic systems. Performance Metrics: Insertion loss of ≤0.35dB (typical 0.15dB) and return loss of ≥20dB exceed industry standards for superior signal integrity. These performance characteristics ensure minimal signal degradation over the 12-meter span, critical for maintaining data integrity in high-speed networks. Compliance and Safety: TAA compliance ensures eligibility for government and military procurement requirements. RoHS and ELV directive compliance demonstrate commitment to environmental responsibility. OFNR riser-rated jacketing provides fire safety in building installations, meeting critical safety codes. Physical Design: The 1.8mm outer diameter provides flexibility for tight spaces while maintaining durability. Red jacketing aids in network organization and identification. Precision connectors ensure optimal mating and minimal insertion/withdrawal cycles required. Quality Assurance: Every cable undergoes attenuation testing per ANSI/TIA/EIA-455-171-A-2001 standards before shipment. The 90-day limited warranty protects your investment. Applications: Ideal for connecting telecommunications equipment, network switches, routers, and fiber optic transmission systems. Commonly used in data centers, telecom facilities, and enterprise networks requiring reliable singlemode fiber connectivity.
