The JBX43231 LC/APC to FC/APC simplex singlemode fiber patch cable represents a critical component for modern network infrastructure, telecommunications systems, and fiber optic installations requiring precise signal transmission over extended distances. **Technical Excellence:** This 50-meter cable features a 9/125 singlemode core constructed from premium G.657.A1 glass fiber, optimized for low attenuation and minimal signal degradation. With insertion loss ratings of ≤0.35dB and return loss ≥20dB, it meets professional-grade performance standards for enterprise-level deployments. The cable undergoes comprehensive attenuation testing per ANSI/TIA/EIA-455-171-A standards, ensuring consistent performance at both 1310nm and 1550nm transmission wavelengths—the standard bands for long-distance telecommunications. **Compliance & Safety:** TAA compliance makes this cable ideal for government contracts and sensitive installations. RoHS/ELV directive adherence ensures environmental responsibility and regulatory compliance across EU and North American markets. The riser-rated (OFNR) jacketing provides fire safety certification for vertical cable runs within buildings. **Practical Design Features:** The distinctive yellow jacket enables quick visual identification in complex cable management scenarios, reducing installation errors and maintenance confusion. The 1.8mm outer diameter provides compatibility with standard cable routing infrastructure. Simplex configuration makes this ideal for unidirectional transmission applications or environments where separate send/receive paths are preferred. **Versatile Applications:** Perfect for fiber-to-the-premises (FTTP) networks, data center interconnects, telecommunications backhaul, laboratory testing, and equipment testing environments. The 50-meter length accommodates mid-range facility connections without excessive attenuation. **Customization & Support:** Custom lengths are available for specialized installations. Ships from multiple US locations (Danville CA, Fort Worth TX, Beaufort SC) ensuring rapid delivery. Backed by a 90-day limited warranty and comprehensive product documentation supporting proper installation and maintenance protocols.
