The JBX43647 30-meter ST/APC to LC/UPC simplex singlemode fiber patch cable is engineered for professional network environments requiring reliable, high-fidelity signal transmission. This cable connects ST/APC connectors—known for their precision and low return loss—to LC/UPC connectors, the industry standard for modern data centers and telecom infrastructure. **Key Technical Specifications:** Built around a 9/125 singlemode fiber core, this cable excels in long-distance transmission with minimal signal loss. The attenuation rating of 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm ensures excellent performance across telecommunications wavelengths. With insertion loss capped at ≤0.35dB and return loss exceeding 20dB, this cable maintains signal integrity and minimizes reflections that could degrade network performance. **Durability and Compliance:** The 1.8mm diameter cable features a riser-rated (OFNR) yellow jacket that provides protection while offering superior visibility for cable management and identification. The yellow color aids in visual organization of complex fiber networks. Manufactured with G.657.A1 glass fiber, it supports bend-insensitive applications while maintaining performance standards. **Regulatory Standards:** Fully TAA compliant and manufactured to RoHS/ELV specifications, this cable meets stringent government procurement requirements. It has been attenuation tested per ANSI/TIA/EIA-455-171-A-2001 standards, ensuring consistent quality and performance. **Flexibility and Customization:** While this listing features the 30-meter length, custom lengths are available to match specific installation requirements. This flexibility simplifies inventory management and ensures precise cable lengths for your deployment. **Applications:** Ideal for data centers, telecommunications facilities, enterprise networks, and any installation requiring single-strand fiber connectivity. Perfect for connecting network equipment, servers, and telecom infrastructure where simplex (one-way) transmission is appropriate. **Warranty and Support:** Backed by a 90-day limited warranty and shipped from strategically located warehouses (Danville CA, Fort Worth TX, or Beaufort SC) for rapid delivery. Enjoy free standard shipping on orders exceeding $99. Invest in reliable, standards-compliant fiber connectivity with the JBX43647—the professional choice for mission-critical networks.
