The JBX89174 is a professional-grade 65-meter SC/SC Duplex Singlemode Fiber Patch Cable designed for mission-critical network applications requiring maximum performance and reliability. This optical accessory combines precision engineering with industry compliance to deliver consistent, high-quality fiber signal transmission. **Technical Specifications:** Built with 9/125 singlemode fiber and G.657.A1 glass fiber technology, this cable provides exceptional signal integrity across extended distances. The 1.8mm outer diameter ensures compatibility with standard cable management systems while maintaining flexibility for installation. Insertion loss is measured at ≤0.35dB (0.15dB typical), with return loss exceeding 20dB—both critical metrics for maintaining signal quality in demanding environments. **Attenuation Performance:** Tested in accordance with ANSI/TIA/EIA-455-171-A-2001 standards: • At 1310nm: 0.25 dB/km • At 1550nm: 0.35 dB/km **Connector Configuration:** Features SC/UPC to SC/UPC connectors in Type A to B Crossover polarity, the industry-standard configuration for duplex patch cords. This enables simultaneous bidirectional data transmission essential for modern network architectures. **Compliance & Safety:** Fully TAA compliant and RoHS certified (EU Directive 2002/95/EC), ensuring suitability for government and enterprise procurement. The OFNR riser-rated jacketing meets building code requirements for installations in walls and air spaces without conduit. **Applications:** Ideal for: • Data center connectivity and backbone networks • Telecommunications infrastructure • Campus and enterprise network installations • Long-distance signal transmission requiring minimal loss • High-speed optical networking systems **Customization & Support:** Custom lengths are available to meet specific installation requirements. Ships from multiple U.S. locations (Danville CA, Fort Worth TX, Beaufort SC) with free standard shipping on orders exceeding $99. Backed by a 90-day limited warranty ensuring peace of mind for your network investment.
