The JBX88394 65-meter ST/ST duplex singlemode fiber patch cable represents a premium solution for mission-critical network installations. Constructed with precision-engineered 9/125 singlemode glass fiber compliant with G.657.A1 standards, this cable delivers superior performance in long-distance signal transmission applications. Key Technical Specifications: The cable features exceptional optical performance with attenuation rates of 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm. Insertion loss testing confirms performance at ≤0.35dB (typical 0.15dB), while return loss exceeds 20dB, ensuring minimal signal reflection and maximum data integrity. The duplex configuration with Type A to B crossover polarity enables seamless connectivity in standard network topologies. Compliance and Durability: TAA compliant and RoHS/ELV certified per EU directive 2002/95/EC, this cable meets stringent government procurement standards. The OFNR riser-rated purple jacket provides fire resistance suitable for vertical cable runs, while the robust 1.8mm outer diameter withstands repeated handling and installation stress. Applications and Use Cases: Ideal for data centers, telecommunications facilities, government networks, and enterprise campuses requiring high-performance fiber connectivity. The 65-meter length accommodates mid-range facility distances while maintaining signal quality. ST/UPC polished connectors ensure low-loss, reliable connections in legacy and modern network architectures. Customization Available: Custom lengths available for specific installation requirements. Multiple U.S. and international manufacturing locations ensure consistent quality and rapid fulfillment. Warranty and Support: 90-day limited warranty provides peace of mind. Free standard shipping on orders exceeding $99 reduces total cost of ownership for bulk installations.
