The JBX43652 Fiber Patch Cable represents precision engineering for telecommunications and data center professionals. This 55-meter ST/APC to LC/UPC simplex singlemode cable combines industry-leading performance with compliance certifications required by government and enterprise customers. **Technical Excellence:** Built on a 9/125 singlemode core with G.657.A1 glass fiber, this cable delivers exceptional optical performance. Insertion loss of ≤0.35dB (0.15dB typical) and return loss exceeding 20dB exceed standards for long-distance signal transmission. Performance testing confirms compliance with ANSI/TIA/EIA-455-171-A-2001, ensuring reliable operation across telecommunications wavelengths at 1310nm and 1550nm. **Construction & Durability:** The riser-rated (OFNR) yellow jacket provides fire-resistant protection suitable for indoor building installations while offering superior visibility for identification and troubleshooting. The 1.8mm outside diameter provides flexibility without compromising structural integrity. Plastic accessories and sturdy connectors withstand repeated installation and maintenance cycles. **Compliance & Procurement:** TAA compliance and RoHS/ELV certification make this cable eligible for government contracts and enterprises with strict procurement policies. Manufactured in Taiwan, United States, and China, the product maintains consistent quality across multiple production facilities. **Applications:** Ideal for telecommunications infrastructure, data center interconnects, enterprise networks, and long-distance fiber runs. The simplex configuration supports unidirectional transmission, perfect for applications requiring dedicated send or receive paths. Custom lengths are available for specialized deployment requirements. **Value & Support:** Competitively priced with free standard shipping on orders exceeding $99. Multiple warehouse locations (Danville CA, Fort Worth TX, Beaufort SC) ensure fast delivery nationwide. Comprehensive 90-day limited warranty provides confidence in long-term reliability. **Installation Considerations:** Carefully manage bend radius during installation to maintain optimal performance. The straight-through polarity design ensures straightforward connectivity without special configuration. Professional-grade construction withstands demanding installation environments while maintaining performance specifications throughout service life.
