The JBX85152 2.5m SC/SC Duplex 9/125 Singlemode Fiber Patch Cable represents professional-grade connectivity solutions for fiber optic networks. This carefully engineered cable combines reliability, performance, and compliance standards essential for modern telecommunications infrastructure. **Technical Specifications:** This duplex patch cable features dual 9/125 singlemode fibers optimized for long-distance, high-bandwidth communication. The 1.8mm outer diameter provides a balance between durability and flexibility for routing in constrained spaces. Operating across industry-standard wavelengths of 1310nm and 1550nm, the cable delivers exceptional performance with typical insertion loss of only 0.15dB and return loss exceeding 20dB. The G.657.A1 glass fiber specification ensures compatibility with next-generation network architectures while maintaining backward compatibility. **Performance & Reliability:** Built to ANSI/TIA/EIA standards, each cable undergoes rigorous attenuation testing to ensure consistent performance. The SC/UPC connectors provide reliable Type A to B crossover configuration, the industry standard for duplex fiber applications. With attenuation ratings of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm, this cable minimizes signal degradation over longer runs. **Compliance & Safety:** Full RoHS/ELV compliance and EU Directive 2002/95/EC certification ensure environmental responsibility and regulatory adherence. The OFNR (Riser Rated) jacket meets fire safety codes for in-building vertical installations, making this cable suitable for backbone and riser applications in commercial facilities. **Ideal Applications:** - Telecommunications network interconnections - Data center backbone connectivity - Campus network fiber runs - Building-to-building connections - Carrier-grade network infrastructure **Custom Solutions Available:** Require a different length? This cable is available in custom lengths to match your specific network topology requirements.
