The JBX43497 30-meter ST/APC to ST/UPC Simplex 9/125 Singlemode Fiber Patch Cable represents the ideal solution for professional fiber optic installations demanding precision and reliability. This TAA-compliant cable integrates advanced fiber technology with military-grade connectors to deliver consistent performance in critical network environments. **Superior Connector Technology:** The combination of ST/APC and ST/UPC connectors provides exceptional flexibility. The angled physical contact (APC) connector offers superior return loss performance (≥20dB), reducing signal reflection and interference, while the UPC end ensures compatibility with standard installations. This dual-connector configuration eliminates the need for adapter conversion in mixed-network scenarios. **Optical Performance:** Feature a premium 9/125 singlemode core engineered with G.657.A1 glass fiber for optimal signal transmission. Insertion loss measures ≤0.35dB at 0.15dB typical—well below industry standards—ensuring minimal signal degradation across the full 30-meter length. Attenuation performance of 0.25dB/km at 1310nm and 0.35dB/km at 1550nm accommodates both legacy and modern network equipment. **Durability and Compliance:** The yellow OFNR (Optical Fiber Non-conductive Riser-rated) jacket provides flame-resistant protection suitable for vertical runs in multi-story facilities. At 1.8mm outside diameter, the cable offers excellent flexibility while maintaining structural integrity. RoHS/ELV compliance and TAA certification ensure regulatory adherence for government and enterprise procurement. **Applications:** Ideal for telecommunications infrastructure, data center backbone connections, long-distance signal transmission, and enterprise network upgrades. The simplex design accommodates single-direction transmission requirements. **Warranty and Support:** 90-day limited warranty with free standard shipping on orders over $99. Available in custom lengths for specialized installations. **Technical Standards:** Manufactured to ANSI/TIA/EIA-455-171-A standards with attenuation testing verification. Ships from multiple US locations (Danville CA, Fort Worth TX, Beaufort SC) ensuring rapid delivery.
