The JBX43683 60-meter LC/UPC to FC/APC simplex singlemode fiber patch cable represents professional-grade connectivity for demanding telecommunications and data center environments. This cable combines precision engineering with proven reliability to ensure optimal signal integrity across extended distances. **Technical Excellence:** Constructed with G.657.A1 singlemode fiber featuring a 9/125 micron core, this cable delivers exceptional performance characteristics. The insertion loss specification of ≤0.35dB (with typical performance of 0.15dB) ensures minimal signal degradation, while return loss of ≥20dB provides excellent signal quality. Attenuation testing follows ANSI/TIA/EIA-455-171-A standards, with performance verified at both 1310nm and 1550nm wavelengths. **Build Quality and Durability:** The cable features an OFNR (Optical Fiber Non-conductive Riser) rated yellow jacket that meets fire safety codes for vertical cable runs in multi-story buildings. The 1.8mm outside diameter provides flexibility for installation in conduit and cable trays without excessive bulk. Constructed with plastic accessories and tested for RoHS/ELV compliance, ensuring environmentally responsible manufacturing. **Connector Configuration:** The LC/UPC to FC/APC connector pairing accommodates mixed-connector network architectures common in legacy and modern installations. The straight-through polarity configuration simplifies troubleshooting and maintains consistent signal paths. Both connector types feature ceramic ferrules designed for low back-reflection performance. **Compliance and Standards:** TAA (Trade Agreements Act) compliance makes this cable suitable for government and institutional procurement. Full compliance with EU Directive 2002/95/EC (RoHS) and comprehensive ANSI/TIA standards ensures compatibility with enterprise network specifications. **Applications:** Ideal for connecting optical network equipment in data centers, telecommunications facilities, research institutions, and enterprise networks. The 60-meter length spans typical intra-building distances, while custom length options accommodate non-standard requirements. **Support and Warranty:** Ships from strategically located US warehouses (Danville, CA; Fort Worth, TX; Beaufort, SC) for rapid delivery. Includes 90-day limited warranty covering manufacturing defects. Custom lengths available for specialized projects. Free standard shipping on orders exceeding $99.
