The JBX87204 represents enterprise-class fiber connectivity for organizations requiring uncompromising optical performance and compliance standards. This 65-meter SC/ST duplex singlemode fiber patch cable combines proven technology with rigorous quality standards to deliver reliable, high-speed data transmission in mission-critical environments. **Technical Excellence:** The 9/125 singlemode core with G.657.A1 specification ensures superior light transmission characteristics across both traditional (1310nm) and long-wavelength (1550nm) bands. With attenuation measurements of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm, this cable minimizes signal degradation over the full 65-meter span. The ≤0.35dB insertion loss and ≥20dB return loss exceed industry standards established by ANSI/TIA/EIA-455-171-A-2001, ensuring optimal signal quality. **Design and Construction:** The duplex configuration with two singlemode strands enables full-duplex communication simultaneously. SC/UPC and ST/UPC connectors provide low-loss connections with predictable performance characteristics. The Type A to B crossover polarity is industry-standard, ensuring immediate compatibility with existing network infrastructure. The 1.8mm diameter jacket fits easily through cable trays and conduit systems. **Compliance and Safety:** TAA compliance makes this cable suitable for government and federal procurement requirements. Full RoHS/ELV certification ensures environmental safety and regulatory compliance. OFNR riser-rated jacketing provides fire safety appropriate for commercial and institutional installations. **Practical Advantages:** The distinctive blue jacket simplifies network documentation and troubleshooting. Custom length options accommodate specific installation requirements. Fast shipping from regional U.S. distribution centers (California, Texas, South Carolina) expedites deployment. Free standard shipping on orders exceeding $99 reduces procurement costs. **Applications:** Ideal for telecommunications systems, data center interconnections, campus networks, and metropolitan area networks requiring singlemode fiber performance. Perfect for upgrades to existing SC/ST infrastructure or new installations demanding future-proof connectivity. **Quality Assurance:** Every cable undergoes rigorous attenuation testing and optical performance verification. The 90-day limited warranty reflects manufacturer confidence in product reliability. This investment protects your network infrastructure for years of dependable service.
