The JBX42175 80-meter SC/APC duplex single mode fiber patch cable represents professional-grade connectivity for critical network infrastructure applications. Whether you're connecting telecommunications equipment, expanding data center capacity, or establishing long-distance signal transmission, this cable delivers the performance and reliability your network demands. **Technical Excellence** Constructed with 9/125 single mode fiber (SMF) and G.657.A1 glass fiber technology, this cable achieves exceptional attenuation characteristics: 0.25 dB/km at 1310 nm or 0.35 dB/km at 1550 nm. The measured insertion loss of ≤0.35dB ensures minimal signal degradation over the full 80-meter span, while the return loss of ≥20dB protects against reflective interference that could compromise signal quality. These specifications are verified through ANSI/TIA/EIA-455-171-A-2001 standards testing. **Installation and Compatibility** The SC/APC connectors provide superior performance compared to standard SC/PC connectors, with angled polishing reducing back reflection. Type A to B crossover polarity simplifies integration with existing duplex patch cord infrastructure. The 1.8mm OD ensures easy routing through existing cable management systems while the yellow jacket aids in visual identification and organization. **Standards Compliance and Environment** With TAA compliance, this cable qualifies for federal procurement requirements. RoHS/ELV certification ensures environmental responsibility. OFNR riser-rated jacketing allows installation in plenum and non-plenum environments, providing installation flexibility across diverse building infrastructures. **Practical Value** Available in custom lengths for unique deployment requirements, this cable can be tailored to your specific network topology. Multiple domestic warehouses in Danville, CA, Fort Worth, TX, and Beaufort, SC ensure rapid fulfillment. Free standard shipping on orders exceeding $99 and a 90-day limited warranty demonstrate manufacturer confidence in product quality. **Ideal Applications** Perfect for telecommunications facilities, data centers, college networks, hospital infrastructure, government installations, and any environment requiring reliable single mode fiber connectivity over extended distances. The 80-meter length accommodates building-to-building connections and extensive intra-building runs without requiring intermediate amplification. Choose the JBX42175 for proven performance, standards compliance, and the technical specifications that keep mission-critical networks operational.
