The JBX43541 ST/APC to FC/UPC Simplex Singlemode Fiber Patch Cable represents professional-grade connectivity for telecommunications, data center, and enterprise network applications. This meticulously engineered 1-meter cable delivers the performance, reliability, and compliance features demanded by network professionals and systems integrators. **Technical Excellence** Constructed with G.657.A1 glass fiber, this simplex cable features a precision 9/125 singlemode core optimized for long-distance signal transmission. Rigorous attenuation testing per ANSI/TIA/EIA-455-171-A-2001 standards ensures consistent performance: ≤0.25 dB/km at 1310 nm and ≤0.35 dB/km at 1550 nm. The measured insertion loss of ≤0.35dB (typical 0.15dB) and return loss ≥20dB guarantee minimal signal degradation, critical for maintaining data integrity across your network infrastructure. **Connector Specifications** The ST/APC connector provides angled physical contact geometry, delivering superior return loss performance essential for sensitive optical systems. The FC/UPC connector features ultra-polished physical contact technology. Both connectors employ straight-through polarity configuration, simplifying installation in standard network architectures. **Compliance and Safety** TAA (Trade Agreements Act) compliance ensures this cable meets government procurement requirements, making it ideal for federal, state, and municipal network projects. Full RoHS/ELV compliance and EU directive 2002/95/EC certification demonstrate environmental responsibility. The riser-rated (OFNR) jacket meets building safety codes, enabling safe installation in vertical cable runs and plenum spaces where applicable. **Installation and Visibility** The distinctive yellow jacket provides exceptional visibility in crowded patch panels and cable trays, reducing installation errors and simplifying troubleshooting. The compact 1.8mm outer diameter enables dense cabling configurations without sacrificing durability or signal quality. TAA compliance ensures government procurement eligibility. **Flexible Solutions** While this product ships in 1-meter configuration, custom lengths are available to precisely match your installation requirements. Ships from three US distribution centers (Danville CA, Fort Worth TX, Beaufort SC) with free standard shipping on orders exceeding $99. **Warranty and Support** Each cable includes a 90-day limited warranty, backed by industry-leading customer support. Whether deploying in telecommunications facilities, data centers, or enterprise networks, the JBX43541 delivers the performance and reliability your mission-critical applications demand.
