The JBX87209 90-meter SC/ST duplex singlemode fiber patch cable represents a premium solution for critical network infrastructure requiring extended cable runs with superior signal fidelity. Designed to meet the stringent demands of telecommunications, data centers, and enterprise networking environments, this cable combines professional-grade construction with proven reliability. **Technical Specifications:** This singlemode fiber cable features a 9/125 micron core construction optimized for long-distance, single-wavelength transmission. The SC/UPC to ST/UPC connector configuration provides Type A to B crossover polarity—the most common standard for duplex patch cord installations. The G.657.A1 glass fiber meets modern bend-insensitive fiber specifications, allowing for more flexible routing in dense installation scenarios. **Performance Characteristics:** With insertion loss rated at ≤0.35dB (typical 0.15dB) and return loss ≥20dB, this cable delivers exceptional optical performance. Attenuation specifications of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm support reliable transmission across extended distances. All performance metrics comply with ANSI/TIA/EIA-455-171-A-2001 industry standards. **Installation & Safety:** The 1.8mm outside diameter OFNR (Optical Fiber Non-conductive Riser) rated jacket provides fire-safe operation in plenum and riser installations. This construction balances durability with flexibility, facilitating installation in tight spaces and complex routing scenarios common in modern data centers. **Compliance & Standards:** TAA (Trade Agreements Act) compliant for U.S. government procurement. RoHS and EU directive 2002/95/EC certified, ensuring environmental compliance and suitability for regulated industries. Manufactured in Taiwan, the United States, or China with consistent quality control. **Flexibility & Customization:** While this product ships as a 90-meter cable, custom lengths are available upon request to meet specific installation requirements. This flexibility eliminates waste and ensures optimal cable management in your network infrastructure. **Warranty & Support:** Backed by a comprehensive 90-day limited warranty. Ships free on orders exceeding $99 from distribution centers in Danville, CA; Fort Worth, TX; and Beaufort, SC, ensuring rapid delivery across the continental United States. **Applications:** Ideal for telecommunications networks, data center backbone connections, long-distance LAN/WAN infrastructure, DWDM systems, and any enterprise application requiring reliable singlemode fiber connectivity over extended distances.
