The JBX43548 ST/APC to FC/UPC simplex singlemode fiber patch cable is a professional-grade networking component designed for mission-critical signal transmission applications. Measuring 6 meters in length with the flexibility to order custom lengths, this cable bridges connectivity gaps between equipment with different connector types while maintaining superior signal integrity. Key Technical Features: This singlemode patch cable employs a 9/125 fiber core, the industry standard for long-distance, high-bandwidth telecommunications. The ST/APC connector features an angled polish design that minimizes reflectance, while the FC/UPC connector provides standard polished performance. Both connectors are precision-engineered for consistent, low-loss connections. The cable achieves insertion loss of ≤0.35dB at both 1310nm and 1550nm wavelengths, with typical performance of just 0.15dB, ensuring minimal signal degradation over distance. Durability and Compliance: Constructed with G.657.A1 glass fiber and protected by an OFNR (Riser Rated) yellow jacket, this cable offers enhanced bend radius tolerance and flame resistance suitable for plenum-adjacent installations. The 1.8mm outer diameter facilitates easy cable management and routing through tight conduits. TAA compliance and RoHS/ELV certification ensure this cable meets government procurement requirements and environmental standards, making it ideal for federal, state, and enterprise purchasing requirements. Applications and Use Cases: Perfect for telecommunications networks, data center backbone connections, laboratory equipment interfacing, and any application requiring simplex (one-direction) fiber transmission. The easy-to-identify yellow jacket simplifies network maintenance and troubleshooting. Custom lengths available upon request accommodate specific installation requirements. Quality Assurance: Manufactured to stringent ANSI/TIA/EIA standards with attenuation testing verification. Backed by a 90-day limited warranty and supported by multiple warehouse locations ensuring rapid fulfillment. Eligible for free standard shipping on orders exceeding $99, providing exceptional value for bulk purchases.
