The JBX42389 SC/APC to ST/UPC duplex singlemode fiber patch cable represents a premium solution for demanding fiber optic network applications. This 90-meter cable combines industry-leading performance specifications with compliance certifications required for government and enterprise environments. Technical Excellence: Built with 9/125 singlemode fiber and G.657.A1 glass fiber technology, this cable provides superior signal transmission characteristics. The measured insertion loss of ≤0.35dB (typically 0.15dB) and return loss ≥20dB ensure minimal signal degradation over extended distances. Attenuation testing confirms performance at critical wavelengths: 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm, making it ideal for long-distance telecommunications and data center applications. Durability and Safety: The OFNR riser-rated PVC jacketing provides flame resistance and smoke suppression suitable for in-building vertical runs. The compact 1.8mm outer diameter facilitates easy installation in cable trays and conduits. Constructed from durable plastic accessories with robust connector housings designed to withstand repeated mating cycles. Compliance and Certification: Fully TAA compliant and RoHS/ELV certified per EU directive 2002/95/EC, ensuring compatibility with government procurement standards and environmental regulations. All components tested in accordance with ANSI/TIA/EIA-455-171-A standards. Connector Configuration: The SC/APC male to ST/UPC male configuration with Type A to B crossover polarity represents the industry standard for duplex patch cord applications, ensuring seamless integration with existing network infrastructure. Applications: Ideal for data center interconnects, telecommunications networks, fiber-to-the-premise installations, and specialized laboratory equipment requiring extended cable runs. The yellow color coding aids in network identification and organization. Warranty and Support: 90-day limited warranty backed by multiple US fulfillment centers ensuring rapid delivery and responsive customer support. Custom lengths available for specialized applications.
