The JBX43257 30-meter LC/APC to ST/UPC simplex singlemode fiber patch cable represents the gold standard for precision fiber optic connectivity. Built with industry-leading specifications, this cable is engineered to support mission-critical network infrastructure requiring zero compromise on signal integrity. **Technical Excellence:** This singlemode fiber cable features a 9/125 micron core with G.657.A1 bend-insensitive fiber technology, enabling deployment in tight spaces without performance degradation. The LC/APC connector (angled physical contact) provides superior return loss characteristics (≥20dB), while the ST/UPC connector ensures broad compatibility with existing network infrastructure. Tested insertion loss of ≤0.35dB at 1310nm and 1550nm wavelengths guarantees minimal signal attenuation across the entire 30-meter run. **Compliance & Standards:** Fully TAA-compliant and RoHS/ELV certified, this cable meets federal procurement requirements for government and institutional buyers. Manufacturing standards include strict adherence to ANSI/TIA/EIA-455-171-A-2001 specifications for optical fiber attenuation testing. **Design & Installation:** The distinctive yellow OFNR (Optical Fiber Non-Conductive Riser) rated jacket provides fire safety ratings suitable for building vertical runs and plenum spaces. The 1.8mm diameter jacketing balances flexibility with durability, simplifying routing through conduit and cable trays. The bright yellow color aids in visual identification during installation and maintenance. **Flexibility & Support:** Available in custom lengths beyond the standard 30m configuration, this cable adapts to specific deployment requirements. The 90-day limited warranty provides confidence in product reliability. **Applications:** Ideal for data center interconnects, telecommunications installations, enterprise LANs, and long-distance fiber runs requiring singlemode performance.
