The JBX42318 SC/APC to FC/UPC 35-meter duplex singlemode fiber patch cable represents a premium solution for mission-critical fiber optic network infrastructure. This professionally engineered cable combines superior optical performance with government compliance certifications, making it ideal for enterprise, educational, healthcare, and government telecommunications environments. **Superior Optical Performance** Built with 9/125 singlemode fiber and G.657.A1 glass specifications, this cable delivers exceptional performance across standard and long-wavelength bands. The incredibly low insertion loss (≤0.35dB, typical 0.15dB) minimizes signal degradation, while the ≥20dB return loss ensures minimal signal reflection. Attenuation rates of 0.25dB/km at 1310nm and 0.35dB/km at 1550nm provide industry-leading efficiency over extended distances. **Compliance and Certification** TAA compliant certification ensures eligibility for US government procurement contracts and federal telecommunications projects. RoHS/ELV compliance meets EU environmental directives, while OFNR riser rating allows safe installation in vertical building pathways. All attenuation testing conforms to ANSI/TIA/EIA-455-171-A-2001 standards, guaranteeing consistent quality and performance. **Practical Design Features** The distinctive yellow OFNR jacket provides immediate visual identification during installation, maintenance, and troubleshooting. The compact 1.8mm diameter ensures compatibility with tight routing and cable management systems without sacrificing durability. Type A to B crossover duplex configuration supports simultaneous bidirectional communication essential for modern network protocols. **Versatile Deployment Options** Custom lengths are available for specialized applications beyond the standard 35-meter configuration. Manufactured in Taiwan, the United States, and China with multiple US warehouse locations (Danville CA, Fort Worth TX, Beaufort SC), the cable ships quickly with free standard shipping on orders exceeding $99. **Ideal Applications** Perfect for data center interconnects, campus backbone networks, long-distance telecommunications, research institutions, and government facilities. The cable's low-loss characteristics make it particularly valuable for bandwidth-intensive applications and systems requiring minimal signal degradation. Backed by a 90-day limited warranty and manufactured to the highest industry standards, the JBX42318 delivers reliable, professional-grade performance for your most demanding fiber optic requirements.
