The JBX89084 65-meter LC/ST duplex singlemode fiber patch cable represents the ideal choice for telecommunications professionals, data center managers, and network installers seeking reliable, high-performance fiber connectivity. This cable combines superior optical performance with regulatory compliance and practical design features. Technical Excellence: Built with 9/125 singlemode fiber core and G.657.A1 glass fiber technology, this cable minimizes signal loss while maximizing transmission distance. Independent testing confirms insertion loss of ≤0.35dB with typical performance of 0.15dB, while return loss exceeds 20dB—ensuring pristine signal quality. Attenuation specifications of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm make this cable suitable for both short-haul and long-distance applications. Connector Architecture: The LC/UPC to ST/UPC connector combination with Type A to B crossover polarity eliminates compatibility confusion. LC connectors provide compact, high-density connectivity, while ST connectors offer reliable mechanical performance. The duplex configuration enables simultaneous bidirectional transmission on a single cable run. Compliance & Safety: TAA compliance ensures this cable meets federal procurement requirements, making it ideal for government and enterprise deployments. RoHS/ELV certification confirms environmentally responsible manufacturing. The OFNR riser-rated jacketing safely routes through building risers while meeting fire code requirements. At just 1.8mm diameter, the low-profile design facilitates easier cable management and installation. Applications: Perfect for upgrading network infrastructure, connecting servers to switches, establishing backup communication links, or expanding fiber-optic systems. The 65-meter length accommodates large-scale deployments across buildings or campuses. Value & Support: Available in custom lengths for specialized projects, backed by a 90-day limited warranty, and shipped free on orders exceeding $99 from multiple domestic locations. This purple-jacketed cable combines technical sophistication with practical affordability for professionals demanding reliable fiber connectivity.
