The JBX43604 FC/APC to ST/UPC Simplex Fiber Patch Cable represents the industry standard for reliable, high-speed optical signal transmission. Engineered for telecommunications professionals, network administrators, and data center technicians, this 2.5-meter cable delivers consistent performance in mission-critical applications. **Technical Excellence:** Built with a precision 9/125 singlemode fiber core conforming to G.657.A1 specifications, this cable supports both 1310nm and 1550nm wavelengths with exceptional attenuation characteristics (0.25 dB/km at 1310nm or 0.35 dB/km at 1550nm). Individual attenuation testing per ANSI/TIA/EIA-455-171-A ensures every cable meets strict performance standards. **Premium Connectors:** The FC/APC (Angled Physical Contact) and ST/UPC (Straight) connector combination provides superior return loss (≥20dB) and minimal insertion loss (≤0.35dB typical). This configuration minimizes signal degradation and reflections, critical for maintaining network integrity. **Durability & Compliance:** The 1.8mm outer diameter yellow OFNR jacket offers flame resistance and enhanced protection, suitable for both riser and plenum installations. RoHS and ELV compliant with TAA certification for government procurement. Manufactured in Taiwan, US, and China for reliable sourcing. **Practical Advantages:** Custom length availability accommodates unique installation requirements. The simplex design supports point-to-point connections efficiently. Multi-location US warehousing (Danville CA, Fort Worth TX, Beaufort SC) enables rapid fulfillment with free standard shipping on orders exceeding $99. **Applications:** Perfect for telecommunications networks, enterprise data centers, campus fiber installations, and professional broadcast environments. The 90-day limited warranty provides confidence in long-term deployment. Specifications: Length 2.5m, Outside Diameter 1.8mm, Glass Fiber G.657.A1, Polarity Straight-Through, Insertion Loss ≤0.35dB, Return Loss ≥20dB.
