The JBX88258 6-meter ST/ST duplex singlemode fiber patch cable represents the pinnacle of optical connectivity solutions for demanding telecommunications and network environments. This precision-engineered cable is specifically designed for professionals who require uncompromising signal integrity and reliable performance in critical infrastructure applications. **Technical Excellence** Constructed with 9/125 singlemode fiber and advanced G.657.A1 glass composition, this cable delivers superior performance characteristics. The measured insertion loss of 0.15dB typical (with a maximum of 0.35dB) ensures minimal signal degradation over the 6-meter span. Return loss exceeding 20dB provides excellent signal reflection control. Attenuation rates of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm support both traditional and long-wavelength optical transmission standards. **Compliance and Reliability** Fully TAA-compliant and manufactured to rigorous ANSI/TIA/EIA-455-171-A-2001 standards, this cable satisfies government procurement requirements and enterprise security specifications. The RoHS/ELV compliance ensures environmental responsibility across all manufacturing locations (Taiwan, US, and China). Built with OFNR (Optical Fiber Non-Conductive Riser Rated) jacketing, the cable safely operates in plenum and riser environments. **Practical Design Features** The ST/UPC connector configuration with Type A to B crossover polarity is the industry standard for duplex patch cord applications, providing immediate compatibility with existing infrastructure. The 1.8mm outer diameter enables flexible routing through confined spaces, cable trays, and conduit systems. The robust blue jacket provides excellent visibility during installation and maintenance while resisting UV degradation and physical damage. **Applications** Ideal for data centers, telecommunications facilities, campus networks, and high-speed fiber infrastructure deployments. Perfect for connecting switches, routers, patch panels, and optical multiplexers in mission-critical environments. **Warranty and Support** Every cable includes a 90-day limited warranty ensuring peace of mind. Custom lengths are available for specialized installations. Ships from strategically located US warehouses (Danville CA, Fort Worth TX, and Beaufort SC) with free standard shipping on orders exceeding $99.
