The JBX42528 ST/APC to ST/APC duplex singlemode fiber patch cable represents enterprise-class networking infrastructure designed to meet the most stringent connectivity requirements. Featuring a 35-meter length with Type A to B crossover polarity, this cable is optimized for bidirectional communication in professional telecommunications environments. **Technical Excellence:** Constructed with 9/125 singlemode fiber and G.657.A1 glass composition, this cable delivers superior signal integrity across extended distances. The cable achieves ≤0.35dB insertion loss at 1310 nm and maintains consistent performance at 1550 nm wavelengths. Return loss specifications exceeding 20dB ensure minimal signal reflection and maximum data fidelity. Each cable undergoes rigorous attenuation testing in accordance with ANSI/TIA/EIA-455-171-A standards. **Durability & Compliance:** The 1.8mm outside diameter provides a compact footprint without compromising strength, while the OFNR (Riser Rated) yellow jacket offers flame resistance and durability for building installations. Full RoHS and ELV compliance ensures environmental responsibility, with TAA compliance meeting government procurement standards. The cable ships worldwide from multiple US distribution centers (California, Texas, South Carolina) with 90-day limited warranty protection. **Applications & Benefits:** Ideal for telecommunications networks, data center interconnections, enterprise LAN installations, and long-distance signal transmission. The duplex configuration enables simultaneous bidirectional communication, maximizing efficiency in complex network architectures. Custom lengths are available for specialized requirements, and bulk packaging (10x10x10 cases) supports large-scale deployments. **Why Choose This Cable?** Enjoy reliable connectivity backed by laboratory-tested performance specifications, TAA compliance for government projects, and free standard shipping on orders exceeding $99. The visible yellow identification simplifies cable management and reduces installation errors in complex server environments.
