The JBX43051 50-meter LC/APC to LC/APC simplex singlemode fiber patch cable represents professional-grade connectivity for demanding network environments. This cable is specifically designed for single-mode fiber applications requiring long-distance signal transmission with minimal attenuation and loss. **Key Technical Specifications:** Features a 9/125 singlemode core with G.657.A1 glass fiber construction, ensuring optimal performance across telecommunications wavelengths. The cable delivers insertion loss of ≤0.35dB (0.15dB typical) and return loss ≥20dB, meeting rigorous industry standards. Attenuation rates of 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm enable reliable long-distance transmission. **Design & Construction:** The distinctive yellow OFNR-rated jacket (1.8mm outer diameter) provides both regulatory compliance and easy identification within rack environments. This riser rating ensures safe installation in building plenum spaces and vertical runs. The cable features LC/APC connectors with straight-through polarity, optimizing for low reflection characteristics essential in singlemode applications. **Compliance & Certification:** TAA compliant and manufactured in Taiwan, the United States, or China, this cable adheres to RoHS/ELV directives and EU Directive 2002/95/EC. All attenuation measurements are tested in accordance with ANSI/TIA/EIA-455-171-A-2001 standards, guaranteeing consistent performance and reliability. **Applications:** Perfect for telecommunications networks, data center interconnects, long-distance backbone connections, and enterprise network installations. The 50-meter length accommodates medium to large facility deployments with minimal signal degradation. **Additional Benefits:** - Available in custom lengths for specific installation requirements - Includes 90-day limited warranty - Backed by industry-leading testing and quality assurance - Free standard shipping on orders exceeding $99 - Ships from multiple US locations for fast delivery Invest in reliable fiber connectivity with the JBX43051—engineered for performance, built to last.
