The JBX88218 85-meter ST/ST duplex singlemode fiber patch cable represents a professional-grade solution for telecommunications, data center, and enterprise network environments requiring reliable, long-distance fiber connectivity. Technical Excellence: This cable features a 9/125 singlemode core with G.657.A1 glass fiber composition, specifically designed for maximum signal integrity over extended distances. The construction delivers attenuation rates of 0.25 dB/km at 1310 nm or 0.35 dB/km at 1550 nm, ensuring minimal signal degradation across the full 85-meter span. With typical insertion loss of just 0.15dB and guaranteed performance of ≤0.35dB, combined with return loss exceeding 20dB, this cable meets the stringent demands of modern fiber optic networks. Compliance and Certification: As a TAA-compliant product manufactured across multiple facilities (Taiwan, US, and China), this cable meets government procurement requirements including RoHS/ELV directives (EU 2002/95/EC). The riser-rated (OFNR) jacketing ensures safe installation in vertical cable runs within building walls and conduits. Design Features: The distinctive yellow jacket provides superior visibility for identification, troubleshooting, and network documentation. Standard Type A to B crossover polarity configuration enables immediate deployment without custom wiring. The 1.8mm outside diameter accommodates industry-standard fiber management, patch panels, and distribution frames. Applications and Use Cases: Ideal for backbone connections, campus networks, disaster recovery links, and any infrastructure requiring single-mode transmission over extended distances. Suitable for both 1310nm and 1550nm wavelengths, supporting various network architectures and technologies. Operational Convenience: Custom length availability accommodates unique installation requirements, while fast shipping from multiple domestic locations (California, Texas, South Carolina) ensures rapid deployment. Free standard shipping on orders exceeding $99 provides excellent value for bulk purchases. Quality Assurance: All cables are attenuation-tested per ANSI/TIA/EIA-455-171-A standards with a 90-day limited warranty providing peace of mind for critical network installations.
