The JBX68851 50m LC/ST OM4 Duplex Multimode Fiber Patch Cable represents premium connectivity for modern high-speed network infrastructure. Manufactured to rigorous standards and available in multiple countries (Taiwan, US, China), this cable combines performance, compliance, and durability for mission-critical installations. **Technical Excellence:** Built on OM4 50/125 multimode fiber technology, this cable achieves outstanding attenuation performance: 3.5 dB/km at 850nm and 1.0 dB/km at 1300nm. With measured insertion loss of just 0.15dB typical (≤0.35dB maximum) and return loss exceeding 60dB, it ensures pristine signal integrity for 100GB applications. Attenuation testing follows ANSI/TIA/EIA-455-171-A-2001 standards, guaranteeing measurement accuracy. **Connector Configuration:** The LC/UPC to ST/UPC connector combination with Type A to B crossover polarity represents industry-standard duplex connectivity. This configuration supports bidirectional communication while maintaining optimal performance across network switching fabric. **Safety and Compliance:** Plenum-rated OFNP jacketing permits installation in air-handling spaces without smoke concerns—essential for building code compliance in commercial and government facilities. RoHS and ELV compliance ensures environmental responsibility and adherence to EU directive 2002/95/EC. **Practical Design Features:** The distinctive purple jacket enables instant cable identification in complex network environments, reducing troubleshooting time. Bend-insensitive fiber technology minimizes signal degradation during installation and relocation, while the compact 1.8mm diameter accommodates dense cable management solutions. **Versatility and Customization:** Offered in 50m standard length with custom lengths available for specialized deployments. Free standard shipping on orders over $99 and 90-day limited warranty provide excellent value and peace of mind. **Ideal Applications:** Data center interconnects, telecommunications backbone networks, enterprise campus links, and high-speed storage area networks (SANs) requiring reliable, future-proof fiber connectivity. The JBX68851 combines proven OM4 multimode technology with premium construction, making it the preferred choice for IT professionals and network engineers demanding uncompromising performance.
