The JBX93054 65-meter LC/SC duplex singlemode fiber patch cable represents professional-grade fiber optic connectivity designed for mission-critical network applications. Built with a 9/125 singlemode core and G.657.A1 glass fiber, this cable delivers the low-loss performance essential for long-distance signal transmission in data centers, telecommunications facilities, and enterprise networks. Key Performance Specifications: This cable achieves exceptional performance metrics, including insertion loss of ≤0.35dB (0.15dB typical) and return loss ≥20dB at both 1310nm and 1550nm wavelengths. Attenuation rates of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm ensure minimal signal degradation over extended runs. All measurements comply with ANSI/TIA/EIA-455-171-A-2001 standards, guaranteeing reliability and consistency. Connector Architecture: The LC/UPC to SC/UPC connector configuration with Type A to B crossover polarity represents the industry standard for duplex patch applications. This proven design ensures compatibility with existing infrastructure while maximizing signal integrity. Both connectors feature UPC (Ultra Physical Contact) polish for optimal performance. Construction & Compliance: The orange OFNR-rated jacketing (1.8mm outer diameter) provides flame resistance and smoke suppression properties required by fire codes, making it suitable for plenum and riser applications. The cable's compact profile facilitates efficient cable management in congested equipment racks and data center environments. TAA Compliance & Flexibility: As a TAA-compliant product, this cable meets federal procurement requirements for government contracts. Custom lengths are available for specialized installations, providing flexibility beyond the standard 65-meter configuration. Applications & Use Cases: Ideal for connecting network equipment in fiber-to-the-desktop (FTTD) installations, backbone connectivity in data centers, telecommunications hubs, and any environment requiring reliable singlemode fiber connections. The duplex configuration enables bidirectional communication within a single cable assembly. Quality Assurance: Backed by a 90-day limited warranty and manufactured to exacting standards across facilities in Taiwan, the United States, and China, this cable represents dependable optical connectivity. Free standard shipping on orders exceeding $99, with shipment from strategically located U.S. warehouses ensures rapid delivery to your location.
