The JBX42995 70-meter LC/UPC to LC/UPC simplex singlemode fiber patch cable represents professional-grade connectivity for mission-critical network infrastructure. Engineered to exacting standards, this cable combines superior optical performance with robust physical construction, making it ideal for data centers, telecommunications facilities, and high-speed network deployments. Technical Excellence: Built around a 9/125 micron singlemode fiber core meeting G.657.A1 specifications, this cable delivers industry-leading performance metrics. The insertion loss of ≤0.35dB (0.15dB typical) ensures minimal signal degradation over the 70-meter length, while the ≥20dB return loss specification guarantees clean, reliable optical coupling. Attenuation is precisely controlled at 0.25 dB/km at 1310nm or 0.35 dB/km at 1550nm, meeting ANSI/TIA/EIA-455-171-A-2001 standards. Design and Construction: The 1.8mm outside diameter with OFNR riser-rated jacketing provides excellent flexibility and safety for vertical installations. The bright yellow jacket offers superior visibility for cable identification and management, reducing installation errors and maintenance time. LC/UPC connectors feature industry-standard polarity and repeatability. Compliance and Certification: This cable achieves TAA compliance, meeting federal procurement requirements for government and institutional buyers. Full RoHS/ELV directive compliance (EU 2002/95/EC) ensures environmental responsibility. The 90-day limited warranty provides confidence in product quality. Applications: Ideal for campus networks, building interconnects, patch panel connections, test and measurement setups, and any application requiring single-strand singlemode transmission. The 70-meter length accommodates moderate distance runs without signal regeneration. Customization Available: Require different lengths or specifications? Custom configurations are available to meet your specific network requirements. Free standard shipping on orders exceeding $99, with multiple fulfillment locations ensuring fast delivery.
