The JBX42125 represents a premium solution for fiber optic network infrastructure, offering professional-grade performance in a compact, reliable package. This 3-meter SC/APC to SC/UPC duplex single mode fiber patch cable is specifically designed for applications requiring crossover duplex connectivity, making it ideal for telecommunications equipment, network switches, and data center installations. Technical Excellence: Built with 9/125 single mode fiber core and G.657.A1 glass specifications, this cable delivers superior attenuation performance: 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm. The insertion loss of ≤0.35dB (with typical 0.15dB performance) and return loss of ≥20dB ensure minimal signal degradation across long-distance transmissions. Attenuation testing conforms to ANSI/TIA/EIA-455-171-A-2001 standards, guaranteeing reliable data integrity. Compliance & Safety: TAA compliant for government and institutional procurement, this cable meets all RoHS/ELV directive requirements (EU 2002/95/EC). The riser-rated (OFNR) PVC jacketing provides fire safety certification essential for in-building network installations. Manufacturing across Taiwan, US, and China ensures consistent quality and global supply chain reliability. Practical Design: The distinctive yellow jacket provides easy visual identification in complex network installations, while the compact 1.8mm outside diameter allows flexible routing through cable trays and tight conduit spaces. Type A to B crossover polarity configuration supports the most common duplex patch cord applications, eliminating compatibility confusion. Applications: Ideal for telecommunications infrastructure, enterprise data centers, service provider networks, and government installations where TAA compliance is mandatory. The crossover configuration makes it perfect for connecting equipment with matched connector types while maintaining signal integrity. Value & Support: Enjoy free standard shipping on orders over $99, 90-day limited warranty coverage, and the flexibility of custom length options for specialized installations. Ships from multiple US locations (Danville CA, Fort Worth TX, Beaufort SC) ensuring rapid delivery.
