The JBX89177 80-meter SC/SC duplex singlemode fiber patch cable represents a premium solution for demanding network connectivity requirements. Engineered with 9/125 singlemode fiber and G.657.A1 glass composition, this cable meets stringent telecommunications standards for signal transmission over extended distances. **Key Technical Specifications:** This duplex patch cord features SC/UPC connectors with Type A to B crossover polarity—the industry-standard configuration for most duplex applications. Attenuation performance is outstanding at 1310 nm (0.25 dB/km) or 1550 nm (0.35 dB/km), with insertion loss testing confirming ≤0.35dB maximum (typical 0.15dB). Return loss ≥20dB ensures minimal signal reflection, critical for maintaining data integrity in long-distance transmissions. **Compliance & Durability:** Full TAA compliance makes this cable ideal for government contracts and regulated environments. RoHS/ELV certification meets EU directive 2002/95/EC standards. The 1.8mm outer diameter OFNR-rated (Riser Rated) jacket provides fire resistance suitable for in-building backbone cabling while the vibrant purple coloring simplifies network organization and troubleshooting. **Applications:** Perfect for data center interconnections, long-haul telecommunications, campus networks, and enterprise backbone infrastructure. The 80-meter length accommodates expansive facility layouts while maintaining signal fidelity. **Logistics & Support:** Ships from multiple US locations (California, Texas, South Carolina) for rapid delivery. Includes 90-day limited warranty. Custom lengths available upon request. Free standard shipping applies to orders exceeding $99. Standards compliance verified per ANSI/TIA/EIA-455-171-A-2001 attenuation testing protocols. Invest in fiber infrastructure that delivers consistent performance, regulatory compliance, and professional-grade reliability.
