The JBX43391 SC/APC to ST/APC simplex singlemode fiber patch cable represents a professional-grade solution for organizations requiring dependable optical connectivity. This 1-meter cable combines precision engineering with stringent quality standards to deliver exceptional performance in critical network infrastructure. **Technical Excellence** Features a 9/125 singlemode fiber core specifically designed for long-distance transmission across telecommunications networks. The cable achieves industry-leading specifications with insertion loss of ≤0.35dB (0.15dB typical) and return loss of ≥20dB, ensuring signal integrity across both 1310nm and 1550nm wavelengths. Attenuation testing meets ANSI/TIA/EIA-455-171-A-2001 standards, with performance of 0.25dB/km at 1310nm and 0.35dB/km at 1550nm. **Connector Architecture** The SC/APC and ST/APC connectors provide straight-through polarity configuration, ideal for point-to-point telecommunications applications. The simplex design accommodates single-strand fiber transmission, reducing installation complexity in dedicated signal paths. **Compliance & Durability** TAA-compliant construction ensures government procurement compatibility. RoHS/ELV certification confirms environmental responsibility, while OFNR riser-rating supports installation in non-plenum spaces. The 1.8mm outer diameter facilitates easy routing through conduit and cable trays. Robust plastic accessories and professional-grade materials ensure longevity in demanding environments. **Customization & Logistics** Available in custom lengths beyond the standard 1m configuration, allowing precise fit for any installation requirement. Ships from multiple US locations (Danville CA, Fort Worth TX, Beaufort SC) with free standard shipping on orders over $99. Supported by a 90-day limited warranty. **Ideal Applications** Perfect for telecommunications carriers, data center operators, enterprise network upgrades, and ISP installations requiring TAA-compliant equipment. The distinctive yellow jacket simplifies cable identification and management in complex environments. Whether upgrading existing infrastructure or deploying new networks, this reliable patch cable delivers the performance standards demanded by mission-critical applications.
