The JBX43405 20-meter SC/APC to ST/APC simplex fiber patch cable represents a premium solution for single-strand fiber optic transmission in professional networking environments. This cable combines advanced optical performance with robust construction to meet the demanding requirements of telecommunications infrastructure, data centers, and enterprise networks. **Technical Excellence**: Built around 9/125 singlemode glass fiber with G.657.A1 specifications, this cable delivers exceptional optical performance. The insertion loss rating of ≤0.35dB (0.15dB typical) and return loss of ≥20dB ensures minimal signal degradation even in sensitive applications. Attenuation specifications of 0.25 dB/km at 1310 nm or 0.35 dB/km at 1550 nm provide consistent performance across common transmission wavelengths. Every cable undergoes rigorous attenuation testing in accordance with ANSI/TIA/EIA-455-171-A standards. **Durability and Compliance**: The 1.8mm outer diameter cable features OFNR (Optical Fiber Non-conductive Riser) rated jacketing, allowing safe installation in building riser applications. The yellow jacket provides superior visibility and simplified cable management. TAA (Trade Agreements Act) compliance makes this cable ideal for government and educational institution procurement. RoHS and ELV directives compliance ensures environmental responsibility. **Versatile Applications**: The SC/APC to ST/APC configuration supports various networking scenarios including telecommunications networks, fiber-to-the-desk installations, laboratory testing, and equipment interconnections. The simplex design is perfect for unidirectional transmission requirements or applications using separate transmit/receive cables. **Customization Available**: While this 20-meter version meets standard requirements, custom lengths are available to accommodate specific installation needs. Ships from multiple U.S. locations (Danville CA, Fort Worth TX, and Beaufort SC) with free standard shipping on orders exceeding $99. **Warranty and Support**: Backed by a 90-day limited warranty, ensuring peace of mind for your network infrastructure investment.
