The JBX85083 45-meter LC/ST duplex singlemode fiber patch cable represents the ideal solution for enterprises and service providers requiring reliable, high-performance fiber optic connectivity. This professionally engineered patch cable combines advanced optical specifications with practical deployment features, making it suitable for data centers, telecommunications infrastructure, and campus network installations. Optical Performance & Specifications: Built with 9/125 singlemode core and G.657.A1 glass fiber, this cable delivers exceptional optical characteristics. The insertion loss rating of ≤0.35dB (with typical performance of 0.15dB) ensures minimal signal degradation over the 45-meter span. Return loss of ≥20dB provides superior signal integrity, while attenuation ratings of 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm support both legacy and modern DWDM applications. Connectivity & Compatibility: The LC/UPC to ST/UPC connector configuration with Type A to B crossover polarity ensures compatibility with standard duplex patch cord applications. Both connector types feature ultra-polished (UPC) contact surfaces for optimal performance. The duplex construction allows simultaneous bidirectional communication, essential for full-duplex network operations. Physical Characteristics & Safety: The bright yellow OFNR (Optical Fiber Non-conductive Riser) jacket provides 1.8mm outer diameter protection while meeting stringent fire safety ratings required for in-building deployment. This color coding facilitates quick identification in complex cable management scenarios. The lightweight plastic accessory design simplifies installation and reduces clutter in cable trays and conduits. Compliance & Warranty: Fully tested to ANSI/TIA/EIA standards and RoHS/ELV compliant, this cable meets international environmental and safety requirements. The 90-day limited warranty provides peace of mind for critical network deployments. Customization Options: Available in custom lengths to accommodate specific installation requirements beyond the standard 45-meter configuration, providing flexibility for unique network topologies and layouts.
