The JBX42425 3-meter FC/APC to FC/UPC duplex singlemode fiber patch cable represents the gold standard in optical connectivity solutions. Purpose-built for telecommunications, data center, and enterprise network applications, this cable delivers the performance and reliability mission-critical installations demand. **Superior Performance Specifications** With a 9/125 singlemode fiber core and G.657.A1 glass fiber composition, this cable achieves exceptional signal integrity. The insertion loss specification of ≤0.35dB (0.15dB typical) ensures minimal signal degradation over the 3-meter span. Return loss exceeding 20dB prevents signal reflection interference, while attenuation testing at both 1310nm and 1550nm wavelengths (0.25dB/km and 0.35dB/km respectively) confirms performance across multiple optical windows. **Robust Construction** The 1.8mm outside diameter jacketing provides durability and manageable bend radius characteristics. OFNR riser rating ensures compliance with fire safety codes in vertical cable runs, while the yellow color coding enhances cable identification and management in complex installations. **Compliance & Certification** Fully TAA compliant, this cable meets all Buy American Act requirements for government contracts. RoHS/ELV directive compliance ensures environmental responsibility without compromising performance. The 90-day limited warranty provides peace-of-mind protection on your investment. **Practical Applications** Ideal for connecting telecommunications equipment, network switches, optical distribution frames, and similar devices requiring reliable single-mode optical connectivity. The Type A to B crossover polarity configuration covers the most common duplex patch cord requirements. **Custom Solutions Available** While this cable ships at 3 meters, custom lengths are available to meet specific installation requirements. Free standard shipping on orders over $99, with convenient fulfillment from multiple U.S. locations.
