The JBX42515 ST/APC Duplex Singlemode Fiber Patch Cable represents the pinnacle of fiber optic connectivity solutions for professional network environments. This 3-meter cable is engineered to meet the stringent demands of modern data centers, telecommunications facilities, and mission-critical network infrastructure. **Superior Technical Performance:** Constructed with 9/125 singlemode fiber utilizing G.657.A1 glass standards, this cable delivers exceptional performance characteristics. The ST/APC connectors feature a 8-degree angled physical contact design, minimizing back-reflection and return loss (≥20dB). With insertion loss of only ≤0.35dB (typically 0.15dB), signal degradation is virtually eliminated across wavelengths of 1310 nm and 1550 nm, making this ideal for long-distance, high-speed transmissions. **Robust Construction & Durability:** The 1.8mm outside diameter duplex cable is jacketed with OFNR (Optical Fiber Non-Conductive Riser) rated material, meeting critical fire safety codes. The robust plastic construction ensures durability in high-traffic areas and harsh environmental conditions. The distinctive yellow jacket provides excellent visibility during installation and maintenance, reducing errors and improving network visibility. **Compliance & Certification:** Fully TAA (Trade Agreements Act) compliant for government and institutional procurement. RoHS and ELV directive compliance ensures environmental responsibility. All attenuation measurements are performed according to ANSI/TIA/EIA-455-171-A-2001 standards, guaranteeing consistent, reliable performance. **Versatile Applications:** Perfect for connecting network switches, patch panels, telecommunications equipment, and fiber-to-the-premises (FTTP) installations. The Type A to B crossover polarity configuration is ideal for standard duplex patch cord applications. Custom lengths are available for specialized installations. **Value & Support:** Enjoy free standard shipping on orders over $99, with products shipping from multiple locations (Danville, CA; Fort Worth, TX; Beaufort, SC) for faster delivery. Every cable includes a 90-day limited warranty for peace of mind. Whether you're upgrading existing infrastructure or building new networks, the JBX42515 delivers professional-grade reliability at a competitive price point.
