The JBX43143 SC/APC to SC/UPC simplex singlemode fiber patch cable represents a premium solution for high-performance optical networking environments. This 60-meter cable is engineered with precision to meet the demanding requirements of modern telecommunications infrastructure, data center connectivity, and enterprise network installations. **Technical Excellence:** Constructed with 9/125 micron singlemode fiber core and G.657.A1 grade glass fiber, this cable provides exceptional signal integrity and compatibility with existing singlemode networks. The cable achieves insertion loss of ≤0.35dB (typical 0.15dB) and return loss ≥20dB, ensuring minimal signal degradation over the 60-meter span. At 1310nm, attenuation is 0.25dB/km, while at 1550nm it's 0.35dB/km, meeting industry standards for long-distance fiber transmission. **Superior Connectivity:** The SC/APC to SC/UPC connector combination offers optimal flexibility for mixed-protocol environments. The angled physical contact (APC) connector on one end minimizes back-reflection, while the standard UPC connector on the opposite end ensures broad compatibility. The straight-through polarity configuration simplifies installation and reduces configuration errors. **Professional Grade Features:** The bright yellow outer jacket (1.8mm diameter) provides excellent visibility in dense cable runs while the OFNR riser rating ensures safe operation in commercial buildings. RoHS and ELV compliance demonstrates environmental responsibility, and TAA compliance makes this ideal for government and procurement-restricted applications. **Versatile Applications:** Perfect for telecommunications carrier installations, data center backbone connectivity, fiber-to-the-desk applications, network resilience testing, and enterprise LAN expansions. The custom length availability option allows scaling to specific infrastructure requirements beyond the standard 60m length. **Value and Support:** Shipped from multiple US locations (Danville, CA; Fort Worth, TX; Beaufort, SC) ensuring fast delivery. The 90-day limited warranty and free standard shipping on orders exceeding $99 provide additional peace of mind for your networking investment.
