The JBX85080 30-meter LC/ST duplex singlemode fiber patch cable is an essential component for modern telecommunications and data center infrastructure. This professional-grade cable delivers reliable, high-speed fiber optic connectivity with exceptional performance metrics that exceed industry standards. Technical Excellence: Built with a 9/125 singlemode core and G.657.A1 glass fiber, this cable is engineered for superior signal integrity over extended distances. The cable achieves insertion loss of ≤0.35dB at 0.15dB typical, and maintains return loss ≥20dB, ensuring minimal signal degradation. Whether operating at 1310 nm or 1550 nm wavelengths, the cable delivers consistent attenuation rates of 0.25 dB/km and 0.35 dB/km respectively, making it ideal for both legacy and modern fiber networks. Connectivity & Compatibility: The LC/UPC to ST/UPC connector configuration with Type A to B crossover polarity is the industry standard for duplex patch cords, ensuring seamless integration with existing network equipment. The duplex design accommodates bidirectional communication over a single cable run. Durability & Installation: With an OFNR riser rating, this cable meets fire safety requirements for indoor installations in plenum and non-plenum spaces. The 1.8mm outer diameter provides optimal flexibility for routing through conduit and cable trays without excessive bend radius concerns. The bright yellow jacket aids in quick visual identification during installation and troubleshooting. Compliance & Standards: This cable is RoHS compliant and adheres to EU directive 2002/95/EC, meeting environmental and safety requirements for global deployment. All attenuation testing follows ANSI/TIA/EIA-455-171-A-2001 standards. Customization Available: While this product comes as a 30-meter patch cable, custom lengths are available to meet specific installation requirements. Warranty & Support: Backed by a 90-day limited warranty and available from multiple fulfillment centers (Danville CA, Fort Worth TX, and Beaufort SC), ensuring rapid delivery and local support.
