The JBX42062 LC/APC to SC/UPC duplex singlemode fiber patch cable is engineered for professionals who demand exceptional optical performance and reliability. At 1.5 meters in length, this cable provides the ideal balance between reach and manageability for equipment racks, patch panels, and network distribution points. **Technical Specifications:** This duplex patch cable features dual 9/125 singlemode fiber strands with G.657.A1 grade glass fiber—an advanced specification that supports bend-insensitive performance while maintaining backward compatibility with standard singlemode cables. The LC/APC connectors provide angled physical contact surfaces that minimize reflections, while the SC/UPC interface offers reliable coupling for diverse network equipment. **Performance Characteristics:** Tested to ANSI/TIA/EIA-455-171-A standards, the cable achieves insertion loss of ≤0.35dB (0.15dB typical) and maintains return loss ≥20dB across both 1310nm and 1550nm wavelengths. These specifications ensure minimal signal degradation even in high-bandwidth applications, making it suitable for 10G, 40G, and emerging 100G network deployments. **Compliance & Safety:** As TAA-compliant, this cable qualifies for government and institutional procurement where domestic sourcing is mandated. It carries RoHS and ELV certifications, ensuring environmental responsibility without sacrificing performance. The OFNR (Optical Fiber Non-conductive Riser) jacket rating allows safe installation throughout buildings while preventing harmful fume emissions in case of fire. **Applications:** Ideal for data center interconnects, telecommunications infrastructure, campus networks, and equipment testing environments. The Type A to B crossover polarity is the industry standard for duplex patch cords, ensuring compatibility with conventional network architectures. **Custom Availability:** While this product offers 1.5m standard length, custom lengths are available to meet specific installation requirements. The 1.8mm diameter provides excellent flexibility for tight routing scenarios without compromising structural integrity. **Warranty & Support:** Backed by a 90-day limited warranty and shipped from multiple US distribution centers (Danville CA, Fort Worth TX, Beaufort SC) for rapid delivery. Qualifies for free standard shipping on orders exceeding $99.
