The JBX93089 90-Meter LC/ST Duplex Singlemode Fiber Patch Cable represents the pinnacle of reliable fiber optic connectivity for professional networking applications. Whether you're connecting network equipment in data centers, upgrading telecommunications infrastructure, or establishing mission-critical fiber links, this cable delivers the performance and dependability required in modern networks. **Superior Optical Performance** Built with premium 9/125 singlemode fiber core and G.657.A1 glass fiber technology, this cable minimizes signal degradation over extended distances. The insertion loss of ≤0.35dB (0.15dB typical) and return loss of ≥20dB ensure optimal signal quality. Attenuation is tested to industry standards: 0.25 dB/km at 1310nm or 0.35 dB/km at 1550nm, meeting ANSI/TIA/EIA-455-171-A specifications. **Professional Connector Design** The LC/UPC to ST/UPC connectors feature Type A to B crossover polarity—the most common configuration for duplex patch cords. This connector combination provides secure, reliable connections suitable for both transmitting and receiving fiber signals across your network infrastructure. **Installation & Safety Features** The compact 1.8mm outside diameter enables flexible installation through tight spaces, cable trays, and conduits. The orange jacket provides high visibility for easy cable identification and management in complex network environments. Riser-rated (OFNR) jacketing ensures fire safety compliance for building installations, making this cable suitable for in-wall and above-floor applications. **Compliance & Standards** Fully TAA compliant and certified to RoHS/ELV standards (EU directive 2002/95/EC), this cable meets stringent environmental and procurement requirements. Manufactured to the highest quality standards with facilities in Taiwan, US, and China, each cable undergoes rigorous attenuation testing. **Flexible Purchasing Options** Available in custom lengths to suit your specific installation requirements, this 90-meter standard configuration is ready to ship from multiple US locations (Danville CA, Fort Worth TX, and Beaufort SC). Enjoy free standard shipping on orders over $99, plus a 90-day limited warranty for peace of mind. **Ideal Applications** - Data center interconnections - Telecommunications networks - Campus network links - Server rack connectivity - Network equipment upgrades - Long-distance signal transmission
