The JBX43184 2.5m LC/APC to FC/UPC Simplex Singlemode Fiber Patch Cable represents professional-grade connectivity for modern telecommunications and data center infrastructure. This specialized cable bridges different connector types, providing seamless integration between LC/APC and FC/UPC terminated equipment—a common requirement in heterogeneous network environments. **Technical Excellence** Designed with a 9/125 singlemode core and G.657.A1 glass fiber, this cable delivers exceptional performance characteristics. Insertion loss specifications of ≤0.35dB (0.15dB typical) and return loss ≥20dB exceed industry standards, ensuring minimal signal degradation. Attenuation measurements of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm provide reliable transmission across standard fiber optic wavelengths. All measurements comply with ANSI/TIA/EIA-455-171-A-2001 standards. **Compliance and Safety** The cable is TAA compliant, making it eligible for government procurement contracts. RoHS/ELV certification ensures environmental compliance and safe handling. The OFNR-rated (Optical Fiber Non-conductive Riser) yellow jacket provides excellent visibility during installation and maintenance while meeting strict fire safety requirements. The 1.8mm outside diameter balances durability with space efficiency. **Practical Features** Available in multiple custom lengths beyond the standard 2.5m offering, this cable adapts to various installation scenarios. Shipping from strategically located hubs (Danville, CA; Fort Worth, TX; Beaufort, SC) ensures rapid delivery. With free standard shipping on orders exceeding $99 and 90-day limited warranty protection, this cable combines reliability with excellent value. **Applications** Ideal for telecommunications networks, data centers, enterprise backbone installations, and laboratory fiber optic systems requiring precise, low-loss signal transmission. The simplex configuration supports applications needing single-directional fiber transmission, from surveillance systems to specialized monitoring equipment. **Care and Maintenance** Protect connectors with dust caps when not in use. Avoid excessive bending (minimum bend radius considerations apply) and keep away from high-temperature environments. Regular inspection ensures optimal performance and longevity.
