The JBX88337 80-meter ST/ST duplex singlemode fiber patch cable represents professional-grade connectivity for mission-critical network infrastructure. Designed to meet the most stringent telecommunications standards, this cable combines superior optical performance with robust construction for long-distance data transmission. **Technical Specifications:** The cable features a 9/125 micrometer singlemode fiber core with G.657.A1 glass specification, optimized for wavelengths at both 1310nm and 1550nm. Insertion loss remains exceptionally low at ≤0.35dB (0.15dB typical), while return loss exceeds 20dB—both critical parameters for signal integrity in high-bandwidth applications. Attenuation is rigorously tested per ANSI/TIA/EIA-455-171-A-2001 standards. **Key Features:** - Duplex configuration with ST/UPC connectors on both ends - Type A to B crossover polarity (most common for duplex patch cords) - 1.8mm ultra-compact outside diameter for efficient cable management - OFNR riser-rated jacketing for building code compliance - TAA compliant for government and federal procurement - RoHS/ELV certified for environmental compliance **Applications & Use Cases:** Ideal for telecommunications closets, data centers, campus networks, and government facilities requiring long-distance singlemode connectivity. The 80-meter length eliminates the need for splicing, ensuring maximum reliability. Perfect for backbone connections between buildings or floors where signal quality cannot be compromised. **Quality Assurance:** Each cable is tested in accordance with telecommunications industry standards. The 90-day limited warranty protects your investment, while free standard shipping on orders over $99 makes bulk procurement economical. **Shipping & Availability:** Ships from multiple US distribution centers (Danville CA, Fort Worth TX, Beaufort SC) for rapid delivery. Custom lengths available for specific installation requirements. Carefully packaged to ensure fiber optic integrity upon arrival.
