The JBX91199 40-meter SC/ST Duplex 9/125 Singlemode Fiber Patch Cable represents a robust solution for telecommunications infrastructure requiring government compliance and enterprise-grade reliability. Engineered for professionals managing data centers, telecommunications networks, and mission-critical applications, this cable combines technical excellence with regulatory adherence. Key Technical Specifications: This duplex singlemode cable features a 9/125 micron core construction optimized for long-distance, high-bandwidth communications. The G.657.A1 glass fiber specification ensures compatibility with modern network standards while maintaining backward compatibility with existing installations. With insertion loss of ≤0.35dB and typical performance of 0.15dB, this cable minimizes signal degradation across the full spectrum, performing at 1310nm (0.25dB/km) and 1550nm (0.35dB/km) wavelengths. Return loss exceeds 20dB, providing excellent signal integrity and reduced reflectance. Compliance and Certification: As a TAA-compliant product meeting all government procurement regulations, this cable qualifies for federal contracts and secure network implementations. RoHS and ELV directive compliance ensures environmental responsibility without compromising performance. Third-party attenuation testing follows ANSI/TIA/EIA-455-171-A-2001 standards, guaranteeing accurate specifications. Design and Durability: The OFNR riser-rated jacket provides flame resistance suitable for building interiors while the 1.8mm diameter maintains flexibility for installation in tight spaces. The distinctive green coloring facilitates rapid identification during installations and troubleshooting. The duplex Type A to B crossover polarity configuration accommodates the most common patching scenarios, reducing compatibility concerns. Applications: Ideal for fiber-to-the-premises installations, data center backbone connections, telecommunications hubs, and government facility networking. The 40-meter length bridges substantial distances without requiring additional splicing or signal regeneration. Warranty and Support: Backed by a 90-day limited warranty and available in custom lengths for specialized requirements. Free standard shipping on orders exceeding $99, with multiple fulfillment locations ensuring rapid delivery across North America.
