The JBX83739 40-meter OM2 LC/LC multimode fiber patch cable represents professional-grade connectivity for enterprise data centers, telecommunications facilities, and high-performance networking environments. This duplex cable combines superior optical performance with practical installation advantages, making it an excellent choice for organizations seeking reliable, standards-compliant fiber infrastructure. **Key Features:** Bend-insensitive fiber technology allows installation in tight spaces without compromising signal integrity. The OFNP-rated jacket provides flame resistance and environmental durability. With an outside diameter of just 1.8mm, the cable offers excellent space efficiency while maintaining robust construction. The 1.8mm OD makes routing through cable trays and conduit significantly easier than standard cables. **Technical Excellence:** Tested in accordance with ANSI/TIA/EIA-455-171-A-2001 standards, this cable delivers exceptional optical characteristics. Insertion loss remains at or below 0.35dB (typical 0.15dB), while return loss exceeds 60dB. Attenuation specifications of 3.5 dB/km at 850nm or 1.0 dB/km at 1300nm ensure consistent performance across multimode applications. **Compliance & Quality:** TAA compliance ensures compatibility with government and institutional procurement standards. Full RoHS/ELV certification meets environmental regulations in EU and worldwide markets. The Type A to B crossover polarity configuration is industry standard for duplex patch cords, eliminating confusion during installation. **Value & Convenience:** Available in custom lengths for specific project requirements, this cable adapts to virtually any installation need. Backed by a 90-day limited warranty and eligible for free standard shipping on orders exceeding $99, it delivers exceptional value. Multiple U.S. distribution centers (Danville CA, Fort Worth TX, Beaufort SC) ensure rapid delivery regardless of location. **Ideal Applications:** Data center interconnections, server farm cabling, telecommunications networks, high-speed local area networks, and any OM2 multimode infrastructure requiring reliable 40-meter runs. The purple jacket aids in network organization and cable identification.
