The JBX88277 represents a premium solution for professionals requiring reliable, high-performance fiber optic connectivity over extended distances. This 80-meter singlemode fiber patch cable is engineered to meet the demanding requirements of modern network infrastructure while maintaining exceptional value. Technical Excellence: This duplex cable features a 9/125 singlemode core with G.657.A1 grade glass fiber, specifically optimized for low-loss signal transmission. With measured attenuation of 0.25 dB/km at 1310 nm or 0.35 dB/km at 1550 nm, the cable delivers consistent performance across common telecommunication wavelengths. The exceptional insertion loss rating of ≤0.35dB (0.15dB typical) ensures minimal signal degradation, while return loss of ≥20dB guarantees clean, reliable signal reflection characteristics. Connector Configuration: Equipped with ST/UPC connectors in a Type A to B crossover configuration, this is the most common and versatile duplex patch cord setup. The ST connectors provide secure mechanical coupling with reliable performance in high-vibration environments. The color-coded blue jacket facilitates easy identification and organization within complex network installations. Compliance & Standards: Fully TAA-compliant for government and enterprise procurement, this cable meets EU Directive 2002/95/EC (RoHS/ELV) requirements, ensuring environmentally responsible manufacturing. The riser-rated (OFNR) jacketing provides flame-retardant protection suitable for in-building installations. All attenuation testing follows ANSI/TIA/EIA-455-171-A-2001 standards, guaranteeing accuracy and reliability. Applications: Ideal for telecommunications infrastructure, data center interconnects, campus network extensions, and enterprise fiber backbone deployments. The 80-meter length bridges significant distances while maintaining signal fidelity, making it perfect for floor-to-floor and building-to-building connections. Shipping & Support: Ships from strategically located US warehouses (Danville CA, Fort Worth TX, Beaufort SC) with free standard shipping on orders over $99. Backed by a 90-day limited warranty and available in custom lengths for specialized requirements. Professional-grade reliability meets practical affordability for network professionals.
