The JBX90193 12-meter SC/ST duplex singlemode fiber patch cable represents a premium solution for telecommunications infrastructure, data centers, and high-speed network environments. This professionally engineered patch cable combines superior optical performance with robust construction standards required by modern IT professionals. Optical Performance & Specifications: Built with 9/125 singlemode fiber and G.657.A1 glass fiber technology, this cable achieves exceptional performance metrics. The insertion loss specification of ≤0.35dB (typical 0.15dB) and return loss ≥20dB exceed industry standards, ensuring minimal signal degradation over the 12-meter span. Attenuation rates of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm make this cable suitable for both legacy and modern wavelength-division multiplexing applications. All performance testing adheres to ANSI/TIA/EIA-455-171-A-2001 standards. Connector Configuration: The SC/UPC to ST/UPC connector pairing with Type A to B crossover polarity is the most common duplex patch cord configuration, ensuring seamless integration with existing network infrastructure. Both connectors utilize UPC (Ultra Physical Contact) finish for enhanced performance and durability. Construction & Safety: The 1.8mm outer diameter OFNR (Optical Fiber, Nonconductive, Riser) rated jacketing provides fire safety compliance while maintaining installation flexibility. Plastic accessory materials ensure electromagnetic compatibility and environmental stability. Compliance & Certification: TAA compliant and certified under EU directive 2002/95/EC (RoHS/ELV), this cable meets government procurement requirements and environmental standards. Manufacturing locations in Taiwan, USA, and China ensure quality consistency and supply reliability. Applications: Ideal for telecommunications, data center interconnects, broadcast facilities, and enterprise network upgrades requiring reliable singlemode transmission. The distinctive pink color facilitates quick visual identification in complex cable management scenarios. Warranty & Support: Included 90-day limited warranty provides peace of mind. Custom length options available for specialized installation requirements. Free standard shipping on orders exceeding $99.
