The JBX88234 ST/ST singlemode fiber patch cable represents professional-grade connectivity for demanding network infrastructure applications. This 15-meter duplex cable combines proven ST/UPC connector technology with advanced 9/125 singlemode fiber core, delivering superior performance for long-distance signal transmission. **Technical Excellence** With an insertion loss of just 0.15dB typical (maximum 0.35dB), this cable minimizes signal degradation across extended runs. The G.657.A1 glass fiber specification provides bend-insensitive performance while maintaining compatibility with standard singlemode systems. Return loss of ≥20dB ensures signal integrity, and attenuation rates of 0.25dB/km at 1310nm and 0.35dB/km at 1550nm meet industry standards for reliable telecommunications. **Compliance & Reliability** Full TAA compliance makes this cable ideal for government and federal procurement requirements. RoHS/ELV certification demonstrates commitment to environmental standards. The 90-day limited warranty protects your investment, while OFNR riser-rating enables installation in vertical runs between floors without conduit. **Practical Applications** Designed for data centers, telecommunications hubs, campus networks, and long-distance LAN connections. The distinctive red jacket aids cable identification and organization. Type A to B crossover polarity ensures proper duplex operation. 1.8mm outside diameter fits standard cable management systems. **Specifications Summary** - Length: 15 meters - Connectors: ST/UPC duplex - Fiber Core: 9/125 singlemode - Insertion Loss: ≤0.35dB (0.15dB typical) - Return Loss: ≥20dB - Glass Fiber: G.657.A1 - Jacketing: OFNR riser-rated - Compliance: TAA, RoHS, ELV - Warranty: 90 days Custom lengths available for specific installation requirements.
