The JBX43574 ST/APC to FC/APC Simplex Fiber Patch Cable represents professional-grade optical connectivity designed for demanding telecommunications and data center environments. This 2.5-meter cable bridges two widely-used connector types, making it an essential component for network infrastructure migrations, system upgrades, and hybrid network configurations. **Technical Excellence** Built with 9/125 singlemode fiber, this cable supports long-distance signal transmission with exceptional clarity. The G.657.A1 glass fiber specification ensures compatibility with modern fiber optic systems while maintaining superior bend-radius performance. Insertion loss of ≤0.35dB (typically 0.15dB) minimizes signal degradation, while return loss ≥20dB prevents signal reflection issues. Attenuation rates of 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm meet industry standards for both legacy and contemporary wavelengths. **Compliance and Safety** TAA (Trade Agreements Act) compliance makes this cable suitable for government procurement and regulated industries. RoHS/ELV directive compliance ensures environmental responsibility. The OFNR (Optical Fiber Non-conductive Riser) rating permits safe installation in vertical cable runs and building plenums, meeting fire safety requirements. **Practical Design Features** The distinctive yellow jacket provides immediate visual identification in complex installations, reducing configuration errors. The 1.8mm outside diameter offers flexibility in cable routing and management. Simplex construction ensures straightforward installation where bidirectional communication isn't required. **Flexibility and Support** Custom length options allow precise fitting to your specific installation requirements. Ships from multiple U.S. locations (California, Texas, South Carolina) with free standard shipping on orders exceeding $99. The 90-day limited warranty provides confidence in your investment. **Ideal Applications** Perfect for telecommunications networks, CATV systems, fiber-to-the-home installations, laboratory testing, and data center connectivity. The ST/APC to FC/APC combination supports diverse equipment configurations.
