The JBX43650 ST/APC to LC/UPC singlemode fiber patch cable is engineered for professional network infrastructure applications requiring exceptional signal integrity over extended distances. This 45-meter simplex cable combines precision engineering with enterprise-grade reliability, making it an ideal choice for telecommunications facilities, data center installations, and high-performance network deployments. Key Technical Specifications: This cable features a 9/125 singlemode fiber core with G.657.A1 glass specification, ensuring optimal performance for both 1310nm and 1550nm wavelengths. The ST/APC (Straight Tip/Angled Physical Contact) termination on the transmitting end connects seamlessly to LC/UPC (Lucent Connector/Ultra Physical Contact) receivers, providing straight-through polarity configuration. With an outside diameter of 1.8mm and riser-rated (OFNR) yellow PVC jacket, the cable balances flexibility with fire-safety compliance. Performance Metrics: Attenuation specifications meet ANSI/TIA/EIA-455-171-A-2001 standards with measured performance of 0.25dB/km at 1310nm or 0.35dB/km at 1550nm. Insertion loss testing confirms ≤0.35dB maximum (typical 0.15dB), while return loss exceeds 20dB—critical measurements for minimizing signal degradation and ensuring data integrity. Compliance & Standards: Full TAA compliance certification ensures this cable meets government procurement requirements for telecommunications projects. RoHS/ELV directive compliance (EU 2002/95/EC) demonstrates environmental responsibility. Manufacturing facilities across Taiwan, US, and China provide supply chain flexibility. Practical Advantages: The distinctive yellow jacket provides visual identification in complex installation environments, reducing configuration errors. Custom length availability accommodates specific installation requirements. Free standard shipping on orders exceeding $99 provides excellent value. The 90-day limited warranty protects your investment, backed by rigorous quality testing before shipment. Ideal Applications: Perfect for fiber-to-the-premises (FTTP) installations, long-distance campus network connections, telecommunications equipment interconnection, and high-speed data transmission where signal quality cannot be compromised. The 45-meter length bridges significant distances without requiring intermediate amplification.
