The JBX88413 12-meter ST/ST duplex singlemode fiber patch cable represents a critical component for modern network infrastructure. Manufactured with precision to meet stringent telecommunications standards, this cable bridges network equipment with minimal signal degradation and maximum reliability. **Technical Specifications:** Designed with a 9/125 micrometer core, this singlemode fiber optimizes signal transmission across long distances with exceptionally low attenuation rates of 0.25 dB/km at 1310nm or 0.35 dB/km at 1550nm. The G.657.A1 glass fiber grade ensures bend-insensitive performance while maintaining optical characteristics, allowing for more flexible installation scenarios without compromising performance. **Construction & Durability:** The 1.8mm outer diameter jacket is OFNR riser-rated, meeting fire safety requirements for vertical cable runs in multi-story buildings. Type A to B crossover polarity provides standard duplex configuration for most network applications. RoHS and ELV compliance ensures environmental responsibility and regulatory adherence for enterprise deployments. **Key Performance Metrics:** • Insertion Loss: ≤0.35dB (0.15dB typical) • Return Loss: ≥20dB • Tested to ANSI/TIA/EIA-455-171-A-2001 standards **Applications:** Ideal for data center interconnections, telecommunications facilities, CATV headend connections, and enterprise network backbones. The TAA compliance designation makes it suitable for government and federal projects. The distinctive pink jacket facilitates cable identification and management in complex installations. **Flexibility & Customization:** While this product features 12-meter length, custom lengths are available to match your specific installation requirements. This flexibility eliminates excess cable management issues and reduces clutter in equipment racks. **Support & Warranty:** Each cable includes a 90-day limited warranty and ships with free standard shipping on orders exceeding $99, with shipments from strategically located fulfillment centers ensuring rapid delivery. Invest in reliable fiber connectivity backed by rigorous quality standards and professional-grade construction.
