The JBX88279 90-meter ST/ST duplex singlemode fiber patch cable represents a premium solution for professional network infrastructure deployment. This cable is specifically engineered to meet the rigorous demands of modern telecommunications, data center operations, and enterprise networking environments. **Technical Excellence** Built with a 9/125 singlemode core and G.657.A1 glass fiber, this cable delivers superior attenuation performance at industry-standard wavelengths: 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm. The tested insertion loss of ≤0.35dB (0.15dB typical) ensures minimal signal degradation over the full 90-meter span, while return loss exceeding 20dB prevents signal reflections that could compromise data integrity. **Compliance & Standards** This cable is TAA (Trade Agreements Act) compliant, making it eligible for government and public sector purchases. It meets RoHS/ELV directives (EU 2002/95/EC) and is manufactured to ANSI/TIA/EIA-455-171-A standards, guaranteeing reliability and performance consistency. **Design Features** The duplex configuration with Type A to B crossover polarity supports bidirectional communication on a single cable run. The OFNR (Optical Fiber Non-conductive Riser) jacketing provides fire-safety ratings suitable for vertical cable runs in multi-story buildings. The 1.8mm outer diameter reduces congestion in cable trays and conduits while maintaining robust protection. **Practical Applications** Ideal for backbone connections, server room links, and long-distance campus networks. The 90-meter length eliminates the need for multiple cable runs in large installations, reducing connection points and potential failure points. **Warranty & Support** Backed by a 90-day limited warranty and available in custom lengths for specific installation requirements. Ships with free standard shipping on orders over $99 from multiple U.S. locations for faster delivery.
