The JBX87175 represents a premium solution for organizations requiring dependable singlemode fiber connectivity over extended distances. This 70-meter SC/SC duplex patch cable combines professional-grade construction with cost-effective pricing, making it ideal for both new installations and system expansions in telecommunications and data center environments. **Technical Excellence** Built with 9/125 micron singlemode fiber and G.657.A1 glass composition, this cable delivers outstanding optical performance. The ≤0.35dB insertion loss (0.15dB typical) minimizes signal degradation, while the ≥20dB return loss ensures signal quality across both 1310nm and 1550nm wavelengths. Attenuation rates of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm meet stringent industry standards, validated through ANSI/TIA/EIA-455-171-A-2001 testing protocols. **Compliance & Safety** TAA compliance makes this cable eligible for government and enterprise procurement. RoHS/ELV compliance ensures environmental responsibility, while OFNR (Optical Fiber Non-conductive Riser) jacketing provides fire safety for building installations. The robust 1.8mm diameter jacketing protects the fiber core in demanding environments. **Connector Configuration** SC/UPC connectors offer excellent optical performance and consistent mating. The Type A to B crossover polarity is the industry standard for duplex patch cords, ensuring compatibility with existing network infrastructure without requiring polarity adapters. **Flexibility & Support** Custom lengths are available for specific application requirements. The cable ships from multiple US locations (Danville CA, Fort Worth TX, Beaufort SC), ensuring rapid delivery with free standard shipping on orders exceeding $99. A 90-day limited warranty provides peace of mind for your investment. **Applications** Ideal for data center backbone connections, campus network links, carrier-grade telecommunications, and enterprise LAN/WAN infrastructure. The extended 70-meter length accommodates large facility layouts while maintaining optimal signal performance. Perfect for IT managers, network integrators, and telecommunications professionals seeking reliable, compliant fiber solutions without premium pricing.
