The 80m SC/APC to ST/UPC Simplex 9/125 Singlemode Fiber Patch Cable represents a premium solution for telecommunications professionals, network administrators, and data center technicians requiring dependable fiber optic connectivity. This meticulously engineered cable bridges two different connector types—SC/APC (angled physical contact) on one end and ST/UPC (straight physical contact) on the other—making it essential for mixed-equipment environments. **Technical Excellence** Built with G.657.A1 singlemode glass fiber, this 80-meter cable delivers superior performance characteristics. The 9/125 core specification ensures optimal signal propagation for long-distance telecommunications. Measured insertion loss of ≤0.35dB (typical 0.15dB) and return loss of ≥20dB exceed industry standards, guaranteeing minimal signal degradation and reflection. The cable has been attenuation-tested per ANSI/TIA/EIA-455-171-A-2001, ensuring consistent performance at both 1310nm and 1550nm wavelengths. **Construction and Compliance** The yellow OFNR (Optical Fiber Non-Conductive Riser) rated jacket provides flame-resistant protection suitable for vertical riser installations in commercial buildings. TAA compliance certifies government procurement eligibility, while RoHS/ELV directive adherence ensures environmental responsibility. The 1.8mm outer diameter accommodates standard cable management infrastructure without requiring special conduits. **Applications and Use Cases** This simplex configuration is ideal for: - Unidirectional signal transmission in fiber networks - Laboratory and testing environments - Telecommunications equipment interconnection - Data center patch panel connectivity - Legacy system integration requiring SC/APC to ST/UPC adaptation **Logistics and Support** Manufactured across Taiwan, US, and China facilities, this cable ships from multiple distribution centers in California, Texas, and South Carolina, ensuring rapid delivery. The 90-day limited warranty provides confidence in product reliability. Custom lengths are available for specialized installations, and free standard shipping applies to orders exceeding $99. **Professional Advantage** Choosing this fiber patch cable means investing in telecommunications infrastructure designed for precision performance and longevity. The straight-through polarity ensures straightforward installation, while the distinctive yellow jacket provides easy identification in complex cable environments. Whether upgrading existing networks or establishing new connections, this TAA-compliant singlemode solution delivers the performance telecommunications professionals demand.
