The JBX43022 represents premium-quality fiber optic connectivity engineered for critical network infrastructure. This 55-meter LC/APC to LC/UPC simplex singlemode patch cable is specifically designed for applications requiring low-loss signal transmission and reliable performance. **Key Technical Specifications:** The cable features a 9/125 micron singlemode fiber core with G.657.A1 glass construction, enabling bend-insensitive performance while maintaining optical performance standards. At 1310nm, attenuation measures 0.25dB/km, while 1550nm achieves 0.35dB/km, making it suitable for both telecom and long-distance data applications. The 1.8mm outside diameter with OFNR riser-rated jacketing ensures safe installation in indoor building pathways and cable trays. **Performance & Compliance:** With typical insertion loss of just 0.15dB and return loss exceeding 20dB, this cable minimizes signal degradation across the 55-meter span. TAA compliance makes it eligible for government and federally-funded projects. RoHS/ELV directive compliance ensures environmentally responsible manufacturing. **Applications:** Ideal for data centers, telecom facilities, enterprise networks, and backbone connections where signal integrity is paramount. The LC/APC (angled physical contact) to LC/UPC (ultra physical contact) configuration accommodates mixed network environments. **Convenience Features:** Distributed from three U.S. locations (Danville CA, Fort Worth TX, Beaufort SC) for expedited shipping. Free standard shipping on orders exceeding $99. Custom length options available for unique installation requirements. Professional-grade yellow jacket aids technician identification during maintenance. **Warranty & Support:** Each cable undergoes rigorous ANSI/TIA/EIA-455-171-A testing and includes a 90-day limited warranty, ensuring peace of mind for critical installations.
