The JBX43687 80-meter LC/UPC to FC/APC simplex fiber patch cable represents enterprise-grade connectivity for demanding network environments. Engineered with precision-aligned connectors and premium G.657.A1 singlemode fiber, this cable ensures dependable signal transmission across extended distances. **Key Technical Features:** This simplex configuration carries a single fiber strand optimized for one-directional data transmission. The 9/125 micrometer core/cladding diameter maintains strict tolerances for minimal signal degradation. Measured attenuation rates of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm deliver predictable performance across standard telecommunications wavelengths. The ≤0.35dB insertion loss and ≥20dB return loss exceed industry requirements for telecommunications applications. **Construction & Compliance:** The 1.8mm outside diameter riser-rated (OFNR) yellow jacket provides flame resistance and rugged durability in plenum and non-plenum installations. TAA compliance ensures eligibility for government and federal procurement requirements. RoHS/ELV certification guarantees environmentally responsible materials. Standard compliance testing follows ANSI/TIA/EIA-455-171-A-2001 specifications. **Ideal Applications:** Perfect for data center interconnects, telecommunications networks, campus backbone installations, and long-run fiber deployments requiring reliable LC/UPC to FC/APC connectivity. The straight-through polarity supports seamless integration with existing infrastructure. **Flexibility & Support:** Custom lengths available upon request for specialized installations. Ships from three continental U.S. locations (Danville CA, Fort Worth TX, Beaufort SC) for rapid delivery. Backed by a 90-day limited warranty ensuring customer confidence.
