The 40m LC/SC OM2 50/125 multimode fiber patch cable represents a critical component for modern networking environments requiring reliable, high-performance fiber connectivity. Engineered to professional standards, this yellow duplex cable serves data centers, telecommunications facilities, and enterprise networks demanding robust signal transmission. **Technical Excellence:** This OM2 multimode fiber cable features a 50/125 micron core/cladding ratio optimized for bandwidth up to 500 MHz/km at 850nm wavelength. The precision LC/UPC and SC/UPC connectors deliver exceptional optical performance with insertion loss measured at just ≤0.35dB (typical 0.15dB) and return loss exceeding 60dB. These specifications ensure minimal signal degradation even across the full 40-meter length, making it suitable for backbone connections and high-demand network segments. **Superior Construction:** The cable features bend-insensitive OFNP jacketing with a compact 1.8mm outer diameter, allowing installation in cable trays, conduits, and tight spaces without compromising fiber integrity. The duplex design with Type A to B crossover polarity represents the industry standard for multimode applications, simplifying network deployment and reducing installation errors. **Compliance & Reliability:** Fully TAA compliant for government and federal procurement, this cable meets RoHS/ELV directives (EU directive 2002/95/EC) and is manufactured to the highest environmental standards. Attenuation rates of 3.5 dB/km at 850nm wavelength and 1.0 dB/km at 1300nm ensure predictable performance across various network speeds. The cable is tested per ANSI/TIA/EIA-455-171-A-2001 standards, guaranteeing quality and consistency. **Practical Advantages:** Why choose this patch cable? The 40-meter length bridges longer infrastructure gaps common in larger facilities without requiring additional splicing. Custom lengths are available to perfectly match your network topology. Ships from strategically located U.S. warehouses (Danville CA, Fort Worth TX, Beaufort SC) enabling rapid delivery with free standard shipping on orders exceeding $99. The yellow jacket provides easy visual identification in dense cable environments, reducing troubleshooting time. **Application Scenarios:** Ideal for connecting switches to patch panels, linking separate network segments, and backbone connectivity in multi-story buildings. Suitable for educational institutions, healthcare facilities, financial services, and enterprise campuses requiring dependable multimode fiber infrastructure. **Warranty & Support:** Backed by a 90-day limited warranty ensuring peace of mind with every purchase. Whether upgrading legacy networks or building new infrastructure, this OM2 patch cable delivers proven performance and cost-effective connectivity.
