The JBX88265 20-meter ST/ST duplex singlemode fiber patch cable represents a professional solution for demanding optical fiber network applications. This cable is specifically designed to meet the rigorous requirements of enterprise-level networking infrastructure, from data center implementations to telecommunications facilities. **Technical Excellence:** Features a 9/125 singlemode fiber core with G.657.A1 specification, providing superior bending performance and attenuation characteristics. Tested attenuation specifications guarantee 0.25 dB/km at 1310 nm or 0.35 dB/km at 1550 nm, with typical insertion loss of just 0.15dB—well below industry maximum tolerances of 0.35dB. Return loss performance of ≥20dB ensures minimal signal reflection and data integrity. **Compliance & Standards:** Fully TAA compliant for government and public sector procurement. Meets RoHS/ELV directives and ANSI/TIA/EIA-455-171-A-2001 attenuation testing standards. OFNR riser-rated jacketing provides fire safety compliance for building installations. Includes 90-day limited warranty for peace of mind. **Design Features:** The Type A to B crossover polarity configuration is the most common duplex standard, ensuring compatibility with existing network infrastructure. The compact 1.8mm diameter jacketing facilitates cable routing in confined spaces. Professional blue coloring aids in visual network documentation and fiber organization. **Availability & Value:** Ships from multiple U.S. locations (Danville CA, Fort Worth TX, Beaufort SC) enabling rapid delivery. Free standard shipping on orders exceeding $99. Custom lengths available for specialized applications. Manufactured with quality materials combining plastic accessories with precision fiber optics. **Ideal Applications:** Perfect for connecting network switches, patch panels, and optical transceivers in singlemode environments. Suitable for long-distance high-speed data transmission, telecom backbone infrastructure, and enterprise campus networks. The 20-meter length accommodates moderate to long-distance interconnects within buildings or facilities. Whether upgrading existing infrastructure or building new fiber networks, this cable delivers reliability, performance, and compliance in a cost-effective package.
