The JBX88423 ST/ST Duplex Singlemode Fiber Patch Cable represents a professional-grade solution for enterprise and telecommunications network deployments requiring extended cable runs and superior optical performance. Engineered with a 9/125 micron singlemode fiber core, this 60-meter cable is specifically designed for long-distance applications where signal integrity is paramount. The cable achieves exceptional performance metrics with insertion loss of ≤0.35dB maximum (0.15dB typical) and return loss exceeding 20dB, ensuring reliable data transmission across extended distances. The duplex configuration features Type A to B crossover polarity, the industry-standard for duplex patch cord applications, enabling seamless integration with existing network infrastructure. Constructed with G.657.A1 rated glass fiber, the cable offers superior bend radius characteristics, making installation easier in constrained spaces without compromising performance. The riser-rated OFNR jacketing satisfies building code requirements for vertical runs and enclosed spaces, providing fire safety compliance for commercial installations. TAA compliance certification makes this cable suitable for government contracts and federal procurement initiatives. The distinctive pink jacketing facilitates network organization and quick visual identification during installation and maintenance. Tested in accordance with ANSI/TIA/EIA-455-171-A standards for attenuation at both 1310nm (0.25 dB/km) and 1550nm (0.35 dB/km) wavelengths, ensuring reliable performance across common fiber optic transmission bands. The ST/UPC connectors deliver consistent optical coupling with minimal signal loss. Backed by a 90-day limited warranty and supported by a manufacturer base in Taiwan, the US, and China, this cable offers reliable long-term performance. Ideal applications include data center interconnections, long-distance network backbone connections, telecommunications infrastructure, and specialized fiber optic installations requiring extended cable runs with exceptional optical performance and regulatory compliance.
