The JBX43007 LC/APC to LC/UPC simplex singlemode fiber patch cable represents a professional-grade solution for connecting critical network infrastructure. Manufactured to exacting standards and available from multiple U.S. warehouses, this 5-meter cable is designed for telecommunications, data center, and enterprise networking applications where signal integrity is paramount. **Technical Excellence:** This cable utilizes a 9/125 singlemode fiber core (G.657.A1 specification) engineered for minimal signal loss and maximum clarity. With insertion loss of ≤0.35dB (typically just 0.15dB) and return loss of ≥20dB, the JBX43007 exceeds industry standards for optical performance. Attenuation is measured at 0.25dB/km at 1310nm and 0.35dB/km at 1550nm, ensuring excellent transmission across standard telecommunications wavelengths. The cable measures 1.8mm outside diameter with a protective plastic sleeve and yellow OFNR (Riser-rated) jacket. **Compliance & Reliability:** TAA compliant and RoHS/ELV certified, this cable meets government procurement requirements and environmental standards. It carries a 90-day limited warranty and has been attenuation tested in accordance with ANSI/TIA/EIA-455-171-A-2001 standards, ensuring quality assurance at every stage. **Practical Advantages:** The distinctive yellow jacket simplifies cable management and identification in crowded server racks and distribution frames. The simplex configuration (single strand) makes it ideal for unidirectional signal transmission. LC connectors provide secure, compact connections with push-pull coupling. **Customization & Availability:** While this product comes in a standard 5-meter length, custom lengths are available to perfectly match your network topology. Ships from multiple U.S. locations with free standard shipping on orders exceeding $99, reducing delivery times and costs. **Applications:** Ideal for telecommunications networks, data centers, campus area networks (CANs), and high-speed internet infrastructure where reliable, low-loss singlemode connectivity is essential. The G.657.A1 glass specification also provides improved bend radius tolerance for deployment flexibility.
