The JBX83559 40-meter LC/ST OM2 50/125 multimode fiber patch cable represents a professional-grade solution for organizations requiring dependable optical fiber connectivity. Built with precision engineering, this duplex cable features two OM2 50/125 multimode fibers optimized for short to medium-distance high-bandwidth applications. **Key Technical Features:** This cable delivers exceptional performance characteristics, including insertion loss of ≤0.35dB (0.15dB typical) and return loss exceeding 60dB. Attenuation specifications are carefully tested and certified at 850nm (3.5dB/km) and 1300nm (1.0dB/km), ensuring consistent signal quality. The cable meets ANSI/TIA/EIA-455-171-A-2001 testing standards, providing confidence in real-world performance. **Superior Design & Construction:** The bend-insensitive OFNP jacketing reduces stress on fibers during installation and provides excellent protection in demanding environments. With a compact 1.8mm outer diameter, the cable navigates tight conduits and cable trays efficiently. Type A to B crossover polarity is standard for duplex patch cords, ensuring seamless integration with existing network infrastructure. **Compliance & Certification:** TAA compliant and RoHS/ELV certified per EU directive 2002/95/EC, this cable meets stringent government and enterprise procurement standards. Manufacturing facilities span Taiwan, US, and China, ensuring global availability and consistent quality. **Ideal Applications:** Perfect for data center interconnects, telecommunications facilities, campus networks, and multimedia installations where OM2 multimode fiber is specified. The 40-meter length accommodates building-to-building links and extended backbone runs. **Value & Support:** Backed by a 90-day limited warranty and available in custom lengths for specific project requirements. Free standard shipping on orders exceeding $99, with fulfillment from three strategically located warehouses (Danville, CA; Fort Worth, TX; Beaufort, SC).
