The JBX42325 SC/APC to FC/UPC Duplex Singlemode Fiber Patch Cable represents professional-grade connectivity for mission-critical fiber optic applications. At 70 meters, this cable bridges network equipment while maintaining signal fidelity essential for high-speed data transmission. **Technical Excellence:** Construction utilizes 9/125 singlemode fiber with G.657.A1 glass composition, meeting industry standards for long-distance signal propagation. The cable demonstrates exceptional performance metrics: insertion loss of just ≤0.35dB (0.15dB typical) and return loss ≥20dB. Attenuation testing confirms performance at both 1310nm (0.25 dB/km) and 1550nm (0.35 dB/km) wavelengths, ensuring compatibility with diverse network infrastructures. **Installation & Compliance:** The OFNR riser-rated jacketing ensures safe installation in building plenums and vertical runs. TAA compliance makes this cable suitable for government and federal procurement projects. RoHS/ELV directive compliance reflects commitment to environmental sustainability. The robust 1.8mm outer diameter provides flexibility for routing through conduit while maintaining durability. **Duplex Configuration:** Type A to B crossover polarity enables two-way signal transmission in a single cable assembly, streamlining installation and reducing cable clutter. The duplex design is ideal for full-duplex communication protocols commonly used in modern telecommunications. **Applications:** Perfect for data centers, telecommunications facilities, broadcast facilities, and enterprise network infrastructure. Suitable for connecting DWDM terminals, optical line terminals, and cross-connect panels. **Convenience & Support:** Available in custom lengths for specific installation requirements. Ships from strategically located U.S. distribution centers (California, Texas, South Carolina) with free standard shipping on qualifying orders. Each cable includes a 90-day limited warranty. Compliance certifications and rigorous testing provide confidence in long-term reliability and performance consistency.
