The JBX88426 75m ST/ST Duplex Singlemode Fiber Patch Cable represents professional-grade optical connectivity designed for mission-critical network infrastructures. This duplex configuration features two individual 9/125 singlemode fiber strands, enabling bidirectional communication in a single compact cable assembly. Technical Excellence: Engineered to ANSI/TIA/EIA standards, this cable delivers tested performance with insertion loss of ≤0.35dB (typical 0.15dB) and return loss ≥20dB. The attenuation specifications of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm ensure minimal signal degradation over the 75-meter span, making it suitable for long-distance premises cabling. Constructive Design: The G.657.A1 glass fiber offers enhanced bend-insensitivity while maintaining singlemode performance. The 1.8mm outside diameter provides compact routing through existing cable pathways. OFNR riser-rated jacketing ensures fire safety compliance in vertical building runs, critical for commercial installations. Compliance & Certification: TAA compliance certifies this cable for government and enterprise procurement requirements. RoHS/ELV directive compliance demonstrates environmental responsibility. ST/UPC connectors with Type A to B crossover polarity are standard for duplex patch cord applications. Versatile Applications: Perfect for connecting network switches, fiber optic panels, and telecommunications equipment. Ideal for data centers, enterprise networks, and telecommunications facilities requiring reliable, tested optical pathways. Flexible Solutions: Custom lengths available to match your specific installation requirements. Shipped from multiple U.S. locations with free standard shipping on orders over $99. 90-day limited warranty provides confidence in product reliability.
