The JBX43641 ST/APC to LC/UPC Simplex Fiber Patch Cable represents an ideal solution for telecommunications professionals, data center operators, and network technicians requiring reliable fiber optic connectivity. **Technical Excellence:** Constructed with 9/125 singlemode fiber and G.657.A1 glass core, this 9-meter cable delivers predictable, low-loss performance. The insertion loss specification of ≤0.35dB (0.15dB typical) at both 1310nm and 1550nm wavelengths ensures minimal signal degradation, while the ≥20dB return loss prevents signal reflection interference. All attenuation measurements comply with ANSI/TIA/EIA-455-171-A-2001 standards. **Connector Compatibility:** The ST/APC to LC/UPC connector configuration bridges different network architectures, allowing connection between legacy ST-based systems and modern LC-based infrastructure. The simplex design transmits signals on a single fiber strand, ideal for unidirectional data transmission or point-to-point connections. **Durability & Safety:** The 1.8mm diameter cable features riser-rated OFNR jacketing, meeting fire safety codes for installation within building walls and plenum spaces. Constructed from durable plastic accessories with international manufacturing standards (Taiwan, US, China), this cable withstands typical networking environments. **Regulatory Compliance:** TAA-compliant certification makes this cable eligible for government procurement and federal projects. Full RoHS/ELV compliance and adherence to EU Directive 2002/95/EC ensure environmental responsibility and hazardous substance restrictions. **Flexibility & Support:** Available in custom lengths beyond the standard 9-meter configuration, allowing precise network design. Ships free on orders over $99 from multiple US locations (Danville CA, Fort Worth TX, Beaufort SC) for rapid delivery. Includes 90-day limited warranty and comprehensive technical support. **Applications:** Perfect for data center interconnects, fiber-to-the-desktop deployments, telecommunications equipment connections, and specialized simplex transmission requirements. The yellow outer jacket aids visual identification in complex cable management scenarios.
