The JBX87193 12-meter SC/ST duplex singlemode fiber patch cable represents a critical component for modern fiber optic networks requiring government and TAA compliance. This meticulously engineered cable delivers enterprise-grade performance for telecommunications, data centers, and government infrastructure projects. **Technical Excellence:** Constructed with 9/125 singlemode fiber and G.657.A1 glass fiber specification, this cable transmits signals with minimal attenuation and exceptional clarity. The optical fiber achieves insertion loss of ≤0.35dB (typically 0.15dB), among the industry's lowest, while maintaining return loss of ≥20dB. Attenuation performance is guaranteed at 0.25 dB/km (1310nm) or 0.35 dB/km (1550nm), meeting rigorous ANSI/TIA standards. **Compliance & Standards:** TAA (Trade Agreements Act) compliant certification makes this cable eligible for government contracts and procurement. RoHS/ELV certification ensures environmental compliance. All components meet EU Directive 2002/95/EC standards. Custom lengths available for specialized installations. **Installation & Performance:** The compact 1.8mm outer diameter facilitates installation in cable trays and conduits without signal interference. OFNR riser-rated jacketing provides superior fire resistance and building code compliance. Type A to B crossover polarity configuration is standard for duplex patch applications, eliminating confusion during installation. **Reliability & Support:** Each cable undergoes rigorous attenuation testing per ANSI/TIA/EIA-455-171-A-2001 standards, guaranteeing performance consistency. The 90-day limited warranty provides peace of mind for mission-critical deployments. Ships from multiple U.S. locations (Danville CA, Fort Worth TX, Beaufort SC) with free standard shipping on orders exceeding $99. **Ideal Applications:** Perfect for telecommunications infrastructure, data center cross-connects, network backbone installations, and government facility upgrades where TAA compliance is mandatory. The duplex configuration streamlines bidirectional communication in a single, organized cable assembly.
