The JBX43500 ST/APC to ST/UPC simplex singlemode fiber patch cable represents a premium solution for telecommunications professionals, data center operators, and network engineers requiring reliable fiber optic connectivity. This 45-meter cable is specifically designed to bridge connection points in complex optical networks where mixed connector types are deployed. **Technical Excellence** Built with 9/125 singlemode fiber core and G.657.A1 glass composition, this cable delivers exceptional performance characteristics. The cable achieves insertion loss specifications of ≤0.35dB (0.15dB typical) and maintains return loss ≥20dB, ensuring minimal signal reflection and optimal data transmission quality. Attenuation rates of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm support both short and long-distance telecommunications applications. **Robust Construction** The 1.8mm outer diameter yellow jacket provides excellent durability while maintaining flexibility for installation in tight spaces. The OFNR (Fiber Optic Non-Conductive Riser) rating ensures safe deployment in building riser and plenum environments, meeting fire safety code requirements. **Regulatory Compliance** Fully TAA compliant for government and institutional purchasing, this cable also meets RoHS and ELV directives (EU 2002/95/EC), making it suitable for environmentally-conscious organizations and international deployments. **Applications** Ideal for telecommunications closets, data centers, campus networks, and FTTH installations. The ST/APC to ST/UPC configuration accommodates mixed-connector networks common in upgrade scenarios and hybrid environments. **Customization & Support** Custom lengths are available for specific installation requirements. The cable ships from three US locations (Danville CA, Fort Worth TX, Beaufort SC) with free standard shipping on qualifying orders. Each unit includes a 90-day limited warranty. **Care & Storage** Store cables in cool, dry conditions away from direct sunlight. Avoid extreme bending (minimum bend radius: 30mm) during installation and operation to preserve fiber integrity and performance characteristics.
