The JBX90208 is a professional-grade 85-meter SC/ST duplex singlemode fiber patch cable engineered for critical telecommunications and data center applications requiring extended cable runs with minimal signal degradation. This cable combines proven optical performance with practical design features that make it an ideal choice for network technicians and IT professionals. Optical Performance & Specifications: Built with a 9/125 micron core and G.657.A1 grade glass fiber, this singlemode cable achieves exceptional attenuation rates of 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm. Insertion loss measures ≤0.35dB (typical 0.15dB), while return loss exceeds 20dB, ensuring clean signal transmission even over extended distances. All measurements comply with ANSI/TIA/EIA-455-171-A-2001 standards. Connector Configuration & Compatibility: The SC/UPC to ST/UPC connector configuration follows the most common Type A to B crossover polarity for duplex patch cords, ensuring compatibility with existing network infrastructure. Both SC and ST connectors are industry-standard interfaces found in telecommunications closets, data centers, and network equipment racks worldwide. Compliance & Reliability: This cable is TAA compliant, meeting Buy American requirements for government and institutional procurement. RoHS/ELV certification confirms environmental responsibility, while the 90-day limited warranty provides peace of mind. The riser-rated OFNR jacketing meets fire codes for in-building cable runs. Practical Features: The vibrant pink jacket provides instant visual identification, reducing installation errors in multi-cable environments. The 1.8mm outside diameter allows routing through tight spaces while maintaining durability. The 85-meter length accommodates long-distance horizontal runs between equipment racks or separate building wings without additional splices. Customization & Availability: Custom lengths are available for applications requiring different cable runs. Manufactured in Taiwan, the US, and China, this cable ships from multiple US locations (Danville CA, Fort Worth TX, Beaufort SC) with free standard shipping on orders exceeding $99. Applications: Ideal for fiber-to-the-desktop deployments, backbone connections between telecom equipment, long-distance LAN extensions, and any application demanding reliable singlemode transmission. Perfect for IT professionals, network technicians, and telecommunications specialists seeking quality components backed by compliance certifications.
