The JBX43125 SC/APC to SC/UPC simplex fiber patch cable represents professional-grade optical connectivity designed for demanding telecommunications and data center environments. This 3-meter cable combines precision engineering with practical functionality to deliver dependable signal transmission across your network infrastructure. **Superior Optical Performance** Constructed with 9/125 singlemode fiber core and G.657.A1 glass fiber, this cable achieves exceptional attenuation rates: 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm. The measured insertion loss of ≤0.35dB (typical 0.15dB) and return loss ≥20dB exceed industry standards, ensuring minimal signal degradation over longer distances. These specifications make it ideal for high-speed data transmission and telecommunications applications where signal quality is paramount. **Connector Flexibility** The asymmetrical design—SC/APC connector on one end and SC/UPC on the other—provides versatility for various network configurations and patch panel arrangements. Both connector types meet professional-grade specifications with precise polishing and alignment for optimal optical coupling. **Compliance and Durability** TAA compliance ensures eligibility for government and federal projects. The yellow OFNR (Optical Fiber Non-conductive Riser) rated jacket meets fire safety standards while providing superior abrasion resistance. Manufactured in Taiwan, the United States, or China with RoHS/ELV compliance, this cable meets strict environmental regulations. The 1.8mm outside diameter enables efficient cable management in space-constrained installations. **Practical Applications** Ideal for data center patch cabling, carrier networks, enterprise telecommunications, and laboratory testing environments. Whether upgrading existing infrastructure or designing new installations, this cable delivers consistent performance. The simplex configuration suits point-to-point connections requiring unidirectional signal transmission. **Convenience and Support** Available in custom lengths to match your specific requirements. Free standard shipping on orders exceeding $99, with rapid delivery from multiple U.S. warehouses in California, Texas, and South Carolina. The 90-day limited warranty provides peace of mind. Whether ordering single cables or bulk quantities (standard case packaging: 10x10x10), professional technical support is available to assist with installation and configuration questions. **Industry-Standard Quality** Tested in accordance with ANSI/TIA/EIA-455-171-A standards, this cable undergoes rigorous quality verification. The professional specifications and reliable performance make it the trusted choice for network professionals who demand excellence.
