The JBX45353 12-meter OM3 50/125 multimode fiber patch cable represents a professional-grade solution for demanding network environments. Engineered to support high-speed data transmission, this duplex cable delivers exceptional performance with minimal signal loss and superior return loss characteristics. **Key Performance Features:** This cable achieves insertion loss of ≤0.35dB (0.15dB typical) and return loss of ≥60dB, ensuring minimal signal degradation over its 12-meter span. The attenuation specifications are optimized for both 850nm (3.5 dB/km) and 1300nm (1.0 dB/km) wavelengths, supporting diverse network architectures. The cable has been attenuation tested in accordance with ANSI/TIA/EIA-455-171-A-2001 standards. **Construction and Durability:** Features SC/UPC to SC/UPC connectors with Type A to B crossover polarity—the most common configuration for duplex patch cords. The bend-insensitive fiber technology minimizes macrobending losses, while the OFNP-rated jacketing provides optimal flexibility and durability. With a compact 1.8mm outside diameter and aqua color coding, installation and identification in crowded cable trays is straightforward. **Compliance and Reliability:** TAA-compliant for government and regulated industry procurement. RoHS and ELV directive compliant (EU 2002/95/EC), meeting environmental standards worldwide. Manufactured in Taiwan, the United States, or China, with warranty coverage backed by a 90-day limited warranty. **Applications:** Ideal for data center patch panels, enterprise backbone networks, telecommunications facilities, and any installation requiring reliable multimode connectivity. The 12-meter length accommodates moderate-distance runs while maintaining signal integrity. **Custom Solutions:** Custom lengths are available to meet specific installation requirements. Free standard shipping applies to orders over $99, with fulfillment from multiple U.S. distribution centers for faster delivery.
