The JBX43193 LC/APC to FC/UPC singlemode fiber patch cable represents a premium solution for professional optical networking applications. This 12-meter cable is specifically designed for environments where signal integrity and reliability are paramount. **Technical Excellence:** Built with 9/125 singlemode fiber and G.657.A1 glass composition, this cable meets ANSI/TIA/EIA-455-171-A-2001 standards. The LC/APC connector provides superior return loss characteristics (≥20dB), minimizing reflections and signal degradation. Typical insertion loss of 0.15dB ensures minimal signal attenuation, with maximum tested loss of 0.35dB at 1310nm and 1550nm wavelengths—critical specifications for long-distance telecommunications. **Compliance & Safety:** TAA compliant certification makes this cable eligible for government and regulated procurement. The riser-rated (OFNR) jacket construction ensures compliance with building fire safety codes. RoHS/ELV directive adherence guarantees environmental responsibility and materials safety. **Practical Features:** The distinctive yellow jacket provides intuitive cable identification in complex installations, reducing setup errors and maintenance time. The 1.8mm outer diameter offers easy routing through existing infrastructure while maintaining durability. At just 12 meters, this length accommodates typical equipment spacing in server rooms, telecommunications closets, and network hubs. **Availability & Support:** Available in custom lengths for specialized applications, this cable ships from multiple US distribution centers ensuring rapid delivery. The 90-day limited warranty provides peace of mind for enterprise deployments. Free standard shipping on orders exceeding $99 makes bulk purchasing economical. **Ideal Applications:** - Data center interconnections - Telecommunications infrastructure - CWDM/DWDM systems - High-speed network backbones - Critical signal transmission environments Whether upgrading legacy systems or deploying new fiber infrastructure, the JBX43193 delivers tested performance, regulatory compliance, and the reliability demanded by modern optical networks.
