The JBX65038 represents the pinnacle of professional fiber optic cable engineering, offering 300 meters of high-performance singlemode connectivity for mission-critical applications. This specialized armored cable is specifically designed for environments where durability, reliability, and superior signal integrity are non-negotiable. **Core Technical Specifications:** Constructed with a 9/125 singlemode core and G.657.A1 grade glass fiber, this cable delivers exceptional signal transmission across long distances. The micro-armored design at 3.0mm diameter provides robust physical protection without compromising flexibility or installation ease. LC/UPC to LC/UPC connectors ensure precise, low-loss connections with consistent performance. **Performance Characteristics:** Attenuation testing in accordance with ANSI/TIA/EIA-455-171-A-2001 standards confirms exceptional performance: 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm wavelengths. This minimal signal loss translates to extended transmission distances and improved network reliability. **Installation & Deployment Features:** The 18" pre-terminated furcated legs facilitate simplified connection to network equipment, while the integrated mesh pull sock prevents cable snags during installation and rerouting. These thoughtful design elements significantly reduce deployment time and potential service disruptions. **Compliance & Sustainability:** Fully RoHS and ELV compliant per EU Directive 2002/95/EC, this cable meets global environmental standards. TAA compliance ensures suitability for government and secure network installations. The plenum-rated OFNP jacketing satisfies fire safety requirements for above-ceiling installations in commercial buildings. **Applications:** Ideal for data center backbone connections, telecommunications infrastructure, enterprise network expansion, and any application requiring armored, long-distance singlemode fiber connectivity. The 300-meter length accommodates large facility spans while maintaining signal integrity. **Availability & Support:** Manufactured in the USA and backed by a 90-day limited warranty. Custom lengths are available for specialized projects. Free standard shipping on orders over $99 from multiple US distribution centers ensures rapid delivery and reliability.
