The JBX89194 SC/ST singlemode fiber patch cable represents professional-grade connectivity for demanding telecommunications and data center applications. This 15-meter duplex cable combines precision engineering with reliable performance standards that network administrators depend on. **Technical Excellence:** Built with a 9/125 singlemode fiber core and G.657.A1 glass fiber, this cable delivers superior optical performance. The insertion loss of ≤0.35dB (typical 0.15dB) and return loss of ≥20dB ensure minimal signal degradation over distance. Attenuation specifications of 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm meet industry standards tested per ANSI/TIA/EIA-455-171-A-2001. **Connector Configuration:** The SC/UPC to ST/UPC connectors are pre-terminated with Type A to B crossover polarity—the most common configuration for duplex patch cords. This eliminates guesswork during installation and reduces network downtime. **Durability and Compliance:** Riser-rated (OFNR) jacketing provides fire resistance and durability for building installations. TAA compliance ensures eligibility for government and federal projects. RoHS/ELV certification demonstrates commitment to environmental standards. The robust 1.8mm diameter outer jacket protects against physical damage while maintaining flexibility for routing. **Practical Applications:** Ideal for telecommunications rooms, data centers, server connections, and network backbone installations. The purple jacket aids quick identification in color-coded network environments, reducing troubleshooting time. **Flexibility and Support:** Custom lengths are available for specialized installations. Ships free on orders over $99 with inventory in California, Texas, and South Carolina for rapid delivery. The 90-day limited warranty provides peace of mind for critical network infrastructure investments. Whether upgrading existing fiber networks or building new installations, the JBX89194 delivers reliable, standards-compliant performance.
