The JBX88274 65-meter ST/ST duplex singlemode fiber patch cable represents the pinnacle of optical connectivity solutions for professionals demanding reliability and performance. Built with a 9/125 micron core and G.657.A1 glass fiber, this cable is specifically engineered for long-distance, high-speed data transmission in singlemode fiber networks. **Superior Performance Specifications:** This cable achieves exceptional attenuation ratings of 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm, with insertion loss tested at ≤0.35dB (0.15dB typical) and return loss of ≥20dB. These performance metrics ensure minimal signal degradation over the 65-meter span, making it ideal for critical network applications. All measurements conform to ANSI/TIA/EIA-455-171-A-2001 standards. **Compliance & Durability:** Full TAA compliance ensures this cable meets government procurement requirements for telecommunications. RoHS and ELV directive compliance guarantees environmental responsibility. The OFNR riser-rated PVC jacket provides fire safety certification necessary for building installations, while the compact 1.8mm diameter allows for flexible routing through conduit and cable management systems. **Optimal Connectivity:** Feturing ST/UPC connectors with Type A to B crossover polarity configuration, this duplex patch cable is the industry standard for most fiber optic network applications. The ST connector design provides reliable connections with consistent performance across repeated insertions. **Practical Advantages:** - 65-meter length eliminates the need for multiple shorter cables - Custom length options available for specialized installations - Ships from multiple US locations (California, Texas, South Carolina) for fast delivery - Free standard shipping on orders exceeding $99 - 90-day limited warranty provides peace of mind **Ideal Applications:** This patch cable is perfect for enterprise data centers, telecommunications facilities, university networks, healthcare systems, financial institutions, and any organization requiring robust singlemode fiber connectivity. Whether connecting core network equipment, extending fiber runs, or establishing backup transmission paths, this cable delivers consistent, reliable performance. **Professional Quality:** Manufactured to exacting standards in Taiwan, the US, or China, each cable undergoes rigorous testing to ensure compliance with all specifications. The professional-grade construction ensures this cable will perform reliably for years in even the most demanding network environments.
