The JBX43210 0.5m LC/APC to FC/APC simplex singlemode fiber patch cable represents professional-grade optical connectivity engineered for mission-critical applications. This single-strand cable combines precision engineering with proven reliability, making it ideal for telecommunications infrastructure, data center interconnections, and enterprise network installations. **Technical Excellence** This singlemode cable utilizes 9/125 G.657.A1 glass fiber, specifically designed for long-distance signal transmission with minimal loss. Tested in accordance with ANSI/TIA/EIA-455-171-A-2001 standards, it delivers exceptional performance metrics: insertion loss of ≤0.35dB (0.15dB typical) at both 1310nm and 1550nm wavelengths, with return loss ≥20dB. These specifications ensure optimal signal strength and minimal reflection, critical for high-speed data transmission. **Connector Compatibility** The LC/APC to FC/APC configuration provides universal compatibility across diverse optical networking environments. APC (Angled Physical Contact) connectors minimize back reflection, essential for sensitive applications. The 1.8mm outside diameter enables flexible routing through tight cable trays and conduit systems without performance degradation. **Compliance and Reliability** TAA (Trade Agreements Act) compliance ensures eligibility for U.S. government and regulated sector procurement. RoHS/ELV certification confirms environmental safety and regulatory adherence. The riser-rated (OFNR) yellow jacket provides flame resistance and visibility, facilitating installation and maintenance in complex network environments. Backed by a 90-day limited warranty, this cable offers confidence in long-term performance. **Installation Flexibility** While this product ships in 0.5m length, custom lengths are readily available to match your specific installation requirements. Multiple U.S. warehouses (Danville CA, Fort Worth TX, Beaufort SC) ensure rapid delivery. Free standard shipping on orders exceeding $99 makes bulk purchasing economical. **Applications** Ideal for telecommunications networks, fiber-to-the-home (FTTH) installations, data center connectivity, research facilities, and enterprise backbone infrastructure. The simplex configuration suits point-to-point transmission scenarios requiring unidirectional signal flow.
