The JBX42464 25-meter FC/APC duplex singlemode fiber patch cable represents professional-grade optical connectivity for telecommunications, data center, and network infrastructure applications. This high-performance cable assembly combines proven FC/APC connector technology with precision-engineered singlemode fiber to deliver reliable, low-loss signal transmission. Key Technical Specifications: The cable features a 9/125 micrometer singlemode core utilizing G.657.A1 grade glass fiber, ensuring compatibility with modern fiber optic networks while maintaining backward compatibility with standard installations. Insertion loss is specified at ≤0.35dB (typical 0.15dB), significantly exceeding industry requirements for patch cable applications. Return loss is rated at ≥20dB, providing excellent signal reflection control. Attenuation performance of 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm meets ANSI/TIA/EIA standards, qualifying for both short-reach and long-distance applications. Connector Configuration: FC/APC connectors are precision-polished at an 8-degree angle, reducing back-reflection and improving overall system performance. The Type A to B crossover configuration is the industry standard for duplex patch cord applications, enabling seamless integration with existing network infrastructure. Physical Characteristics: The 1.8mm outside diameter jacketing is OFNR (Optical Fiber Non-Conductive Riser) rated, meeting flame-spread requirements for vertical cable runs in commercial buildings. The protective yellow jacket facilitates cable identification and management in complex installations. Compact dimensions (5.0" x 0.2" x 5.0") allow flexible routing without signal impairment. Compliance & Sustainability: TAA compliant manufacturing ensures eligibility for federal government purchases. RoHS/ELV compliance satisfies environmental directives, while dual-sourcing from Taiwan, US, and China facilities ensures supply chain resilience and competitive pricing. Applications: Ideal for data center interconnects, telecommunications infrastructure, CATV headends, test equipment connections, and any application requiring duplex singlemode connectivity. The 25-meter length accommodates medium-distance runs without intermediate splicing. Warranty & Support: Backed by a 90-day limited warranty covering manufacturing defects. Custom length options available for specialized installations. Ships from three US distribution centers with free standard shipping on orders exceeding $99.
