The JBX43420 FC/APC to FC/UPC simplex fiber patch cable represents a professional-grade solution for optical signal transmission in telecommunications, data centers, and high-speed network environments. This 0.5-meter cable bridges the connection gap between equipment utilizing different connector polarity standards—FC/APC (angled physical contact) and FC/UPC (ultra-physical contact)—ensuring compatibility across diverse infrastructure setups. Technical Excellence and Performance: Built with 9/125 singlemode fiber conforming to G.657.A1 specifications, this cable delivers exceptional performance metrics. The insertion loss rating of ≤0.35dB (typical 0.15dB) and return loss exceeding 20dB ensures minimal signal degradation over transmission distances. Attenuation performance of 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm meets ANSI/TIA/EIA-455-171-A-2001 standards, making it suitable for long-distance and high-frequency applications. Key Features and Benefits: - TAA-compliant for government and enterprise procurement requirements - RoHS/ELV certified for environmental compliance - OFNR-rated riser jacketing provides fire safety in vertical installations - 1.8mm outside diameter enables space-efficient routing - Distinctive yellow jacket for easy cable identification - 90-day limited warranty provides peace of mind - Available in custom lengths for tailored installations Applications and Use Cases: Perfect for telecommunications infrastructure, fiber-to-the-premises (FTTP) installations, data center interconnects, and laboratory equipment connections. The FC/APC to FC/UPC configuration handles mixed-polarity environments common in legacy system upgrades and hybrid network deployments. Shipping and Support: Ships from strategically located US warehouses (Danville CA, Fort Worth TX, Beaufort SC) with free standard shipping on orders exceeding $99. Manufactured in Taiwan, US, or China with consistent quality standards across all production locations.
