The JBX88194 2.5m ST/ST Duplex Singlemode Fiber Patch Cable represents professional-grade infrastructure connectivity designed for demanding telecommunications and data center environments. This precision-engineered cable delivers exceptional performance characteristics essential for modern high-speed network applications. **Technical Excellence** Built with a 9/125 micron singlemode fiber core utilizing G.657.A1 glass technology, this cable excels in signal transmission efficiency. The low insertion loss specification of ≤0.35dB (with typical performance at 0.15dB) minimizes signal degradation, while the ≥20dB return loss ensures superior signal quality. Attenuation performance meets stringent standards: 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm wavelengths. **Compliance and Standards** This cable satisfies TAA (Trade Agreements Act) compliance requirements, making it suitable for government and large institutional procurement. Full RoHS/ELV certification ensures environmental responsibility. Testing protocols conform to ANSI/TIA/EIA-455-171-A-2001 industry standards, guaranteeing reliable performance metrics. **Practical Design Features** The distinctive yellow jacket aids in network organization and cable identification, while the OFNR riser-rating permits use in building plenum spaces without additional conduit. The compact 1.8mm outer diameter simplifies cable management in tight spaces. ST/UPC connectors feature Type A to B crossover polarity, the standard configuration for duplex patch cords in most installations. **Versatility and Customization** While this cable comes pre-terminated at 2.5 meters, custom lengths are available to accommodate specific installation requirements. This flexibility makes it suitable for diverse applications from network closets to data centers to campus environments. **Warranty and Support** The 90-day limited warranty provides peace of mind for your network infrastructure investment. Free standard shipping on orders exceeding $99 adds cost-effectiveness to bulk purchases. The JBX88194 delivers the reliability, performance, and compliance required for professional fiber optic installations.
