The JBX43682 LC/UPC to FC/APC simplex singlemode fiber patch cable represents a premium solution for professional fiber optic networking applications. With a generous 55-meter length, this cable accommodates larger installations while maintaining signal integrity across extended distances. **Technical Excellence:** Constructed with G.657.A1 singlemode glass fiber featuring a 9/125 micron core, this cable delivers superior performance characteristics. The measured insertion loss of ≤0.35dB (0.15dB typical) and return loss ≥20dB exceed industry standards for optical performance. Testing conducted per ANSI/TIA/EIA-455-171-A standards ensures consistent quality and reliability. **Durability & Compliance:** The 1.8mm outside diameter yellow jacket utilizes OFNR (Optical Fiber Non-Conductive Riser) rating, suitable for vertical runs between floors without conduit. The cable meets RoHS/ELV compliance standards (EU directive 2002/95/EC), and TAA compliance certification ensures procurement eligibility for government and regulated projects. **Performance Specifications:** Attenuation rates of 0.25 dB/km at 1310nm or 0.35 dB/km at 1550nm provide optimal performance across telecommunications wavelengths. The straight-through polarity configuration simplifies installation and reduces configuration errors. **Practical Applications:** Ideal for data centers, telecommunications facilities, educational institutions, and enterprise networks requiring reliable signal transmission. The simplex configuration suits single-channel applications where dedicated transmission paths are required. **Customization & Support:** Custom lengths available to meet specific deployment requirements. Ships from multiple U.S. locations (Danville CA, Fort Worth TX, Beaufort SC) with free standard shipping on orders exceeding $99. Backed by a 90-day limited warranty ensuring customer confidence.
