The JBX88409 ST/ST singlemode fiber patch cable represents a professional-grade solution for organizations requiring reliable, high-performance optical connectivity. This 7-meter duplex cable incorporates fundamental specifications that make it suitable for telecommunications, data centers, and enterprise network infrastructure applications. Technical Excellence: Constructed with 9/125 singlemode fiber and G.657.A1 glass, the cable supports wavelengths at 1310nm and 1550nm with superior attenuation characteristics (0.25 dB/km at 1310nm, 0.35 dB/km at 1550nm). The insertion loss specification of ≤0.35dB (0.15dB typical) and return loss of ≥20dB ensure minimal signal degradation across long transmission distances. ST/UPC connector termination with Type A to B crossover configuration provides the polarity standard most commonly required for duplex patch cord applications. Deployment Advantages: The 1.8mm outside diameter and OFNR riser rating permit installation in plenum and building riser spaces without compromise to fire safety codes. The distinctive pink jacket facilitates rapid identification in high-density patch panel environments, reducing troubleshooting time and installation errors. Custom length availability accommodates specific deployment requirements beyond the standard 7m configuration. Compliance and Quality: TAA compliance qualifies this cable for government purchasing programs and federal procurement requirements. RoHS and EU directive 2002/95/EC certification confirms environmentally responsible manufacturing. All cables undergo attenuation testing per ANSI/TIA/EIA-455-171-A standards, ensuring consistent quality across production batches. The 90-day limited warranty reflects manufacturer confidence in product reliability. Applications: Ideal for telecommunications cabinets, network device interconnection, fiber ring installations, and situations requiring precise signal transmission over medium distances. Organizations migrating to fiber infrastructure or expanding existing singlemode deployments will find this cable meets both performance and compliance specifications. Ships from multiple US locations with free standard shipping on orders exceeding $99, supporting rapid deployment schedules.
