The JBX42735 20-meter ST/APC to LC/UPC duplex singlemode fiber patch cable represents industrial-strength connectivity for mission-critical network applications. This cable combines precision engineering with government-approved specifications to deliver uncompromising performance in enterprise data centers, telecommunications facilities, and government installations. Key Technical Specifications: The cable features a 9/125 micron singlemode fiber core with G.657.A1 glass specification, optimized for long-distance signal transmission. With insertion loss of just 0.15dB typical (≤0.35dB maximum) and return loss exceeding 20dB, this cable minimizes signal degradation across both 1310nm and 1550nm wavelengths. The 1.8mm outside diameter jacketing provides excellent bend radius performance while maintaining durability. Compliance & Certification: TAA compliant and RoHS/ELV certified, the JBX42735 meets stringent government procurement requirements. Pre-tested in accordance with ANSI/TIA/EIA-455-171-A-2001 standards ensures consistent, reliable performance. The OFNR (Optical Fiber Non-conductive Riser) rating confirms fire safety compliance for building installations. Practical Advantages: The distinctive yellow jacket provides instant cable identification in dense installations, reducing installation errors and maintenance time. Type A to B crossover polarity configuration is optimized for duplex patch cord applications. Custom lengths are available for unique installation requirements. Applications & Use Cases: Ideal for connecting telecommunications equipment, network switches, and optical testing instruments. Commonly deployed in backbone networks, equipment interconnects, and fiber-to-the-building installations. Perfect for environments requiring TAA compliance and verified performance metrics. Shipping & Support: Ships from multiple U.S. locations (Danville CA, Fort Worth TX, or Beaufort SC) with free standard shipping on orders exceeding $99. 90-day limited warranty provides peace of mind. Flexible custom length options accommodate specific deployment needs.
