The JBX43205 70-meter LC/APC to FC/UPC simplex singlemode fiber patch cable represents a premium solution for critical telecommunications infrastructure, data centers, and long-distance signal transmission applications. This professionally engineered cable combines superior optical performance with compliance certifications required by government and enterprise customers. **Optical Performance & Specifications:** Built with a 9/125 singlemode core and G.657.A1 glass fiber, this cable achieves exceptional attenuation characteristics: 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm. Typical insertion loss measures just 0.15dB with maximum specification of ≤0.35dB, while return loss exceeds 20dB—exceeding industry standards. All performance metrics are verified through rigorous testing in accordance with ANSI/TIA/EIA-455-171-A 2001 standards. **Connector Technology:** The LC/APC (Angled Physical Contact) connector provides superior return loss performance through its angled polish design, effectively reducing signal reflection. The FC/UPC (Ultra Physical Contact) end offers broad industry compatibility and reliability. This configuration supports simplex (single-fiber) transmission, making it ideal for dedicated unidirectional data paths. **Compliance & Safety:** TAA compliant for Buy American Act procurement requirements, this cable meets RoHS/ELV directives (EU 2002/95/EC) and carries OFNR (Optical Fiber Non-conductive Riser) jacketing certification for safe installation in building risers and plenum spaces. The bright yellow jacket facilitates easy identification and maintenance. **Installation & Availability:** The 70-meter length accommodates extended runs in large facilities without requiring intermediate connectors. Available in custom lengths for specialized applications, with rapid shipping from three US distribution centers. The 1.8mm outer diameter enables flexible routing through cable trays and conduit. **Warranty & Support:** Backed by a 90-day limited warranty and supported by technical expertise. Complimentary standard shipping applies to orders exceeding $99. Perfect for telecommunications professionals, network engineers, and system integrators demanding optical cable performance backed by rigorous testing and compliance certifications.
