The JBX83799 40-meter LC/ST OM2 50/125 multimode fiber patch cable represents a premium connectivity solution for demanding networking environments. This duplex cable combines robust construction with superior optical performance, making it ideal for data centers, telecommunications facilities, and enterprise campus networks. **Key Technical Specifications:** This OM2-grade multimode cable features a 50/125 micron core and cladding design optimized for 850nm and 1300nm wavelengths. The bend-insensitive OFNP jacketing provides enhanced durability while maintaining a compact 1.8mm outer diameter. Attenuation is specified at 3.5 dB/km @ 850nm or 1.0 dB/km @ 1300nm, ensuring minimal signal loss over the 40-meter distance. Insertion loss measures ≤0.35dB (typical 0.15dB), with return loss ≥60dB for clean signal transmission. **Standards & Compliance:** Fully TAA compliant with RoHS/ELV certification, this cable meets federal procurement and environmental requirements. Testing adheres to ANSI/TIA/EIA-455-171-A-2001 standards. The Type A to B crossover polarity is the industry-standard configuration for duplex patch cords, ensuring immediate compatibility with existing network infrastructure. **Construction & Durability:** The purple duplex construction features LC/UPC and ST/UPC connectors optimized for low-loss, high-return-loss connections. Bend-insensitive fiber technology protects against installation stress and supports tighter routing in congested data center environments. **Packaging & Availability:** Ships from multiple US locations (Danville, CA; Fort Worth, TX; Beaufort, SC) with free standard shipping on orders over $99. Custom lengths available for specialized applications. Backed by 90-day limited warranty. **Applications:** Ideal for interconnecting network switches, routers, and fiber patch panels in multimode environments where cost-effective, reliable connectivity is essential.
