The JBX42209 90-meter LC/APC to FC/UPC duplex singlemode fiber patch cable represents a dependable solution for organizations requiring high-performance optical connectivity. Engineered with precision and tested rigorously, this cable meets demanding industry standards while maintaining affordability. Technical Excellence: This duplex cable features 9/125 singlemode fiber with G.657.A1 glass composition, offering the optimal balance between performance and physical flexibility. With typical insertion loss of just 0.15dB and maximum 0.35dB at both 1310nm and 1550nm wavelengths, data integrity remains exceptional over long distances. Return loss specifications of ≥20dB ensure minimal signal reflection, critical for high-bandwidth applications. Connector Configuration: The LC/APC to FC/UPC configuration represents the most common crossover polarity for duplex patch cords. LC (Lucent Connector) APC (Angled Physical Contact) provides superior performance characteristics, while FC (Ferrule Connector) UPC (Ultra Physical Contact) offers broad compatibility across legacy and modern equipment. Industrial-Grade Construction: The 1.8mm diameter yellow OFNR-rated jacket provides riser-rated fire protection suitable for installation in building risers and plenum spaces. TAA compliance and RoHS/ELV certification ensure government and enterprise procurement compatibility. The 90-day limited warranty provides peace of mind. Versatility and Applications: Perfect for data center interconnects, telecommunications backbone installations, laboratory equipment interfacing, and broadcast facility networking. The 90-meter length eliminates splices over extended runs while minimizing attenuation. Custom lengths available to meet specific installation requirements. Quality Assurance: Manufactured to ANSI/TIA/EIA-455-171-A specifications with multi-location fulfillment from Danville CA, Fort Worth TX, and Beaufort SC ensuring rapid delivery.
