The JBX65506 40m OM4 LC/LC Micro Armored Fiber Cable represents professional-grade fiber optic connectivity engineered for demanding network infrastructures. This 2-strand multimode solution combines cutting-edge technology with practical durability for enterprise and datacenter applications. **Superior Performance Specifications:** Built on OM4 50/125 multimode fiber, this cable delivers exceptional bandwidth capabilities supporting 10Gbps over extended distances. The bend-insensitive fiber technology ensures reliable performance even in challenging installation scenarios, reducing signal degradation in tight cable runs. Tested attenuation of 3.5 dB/km at 850nm and 1.5 dB/km at 1300nm meets ANSI/TIA/EIA standards with minimal insertion loss (≤0.35dB typical) and excellent return loss (≥20dB). **Robust Construction & Protection:** The micro armor protection shields the cable from mechanical stress, crush damage, and environmental hazards without sacrificing flexibility. The plenum-rated (OFNP) plastic jacketing makes this ideal for installation in air return plenums and sensitive environments where fire safety codes are critical. The 3.0mm outer diameter accommodates standard cable trays and management systems. **Practical Design Features:** 18" furcated legs enable simplified termination and quick deployments. LC/UPC connectors ensure reliable, low-loss connections in high-density patch panels. Straight-through polarity configuration maintains consistent signal paths throughout your network infrastructure. **Compliance & Quality Assurance:** US-manufactured and TAA compliant, this cable meets RoHS/ELV directives (EU 2002/95/EC). Each unit includes a 90-day limited warranty. Custom lengths are available for specialized applications. Free standard shipping on orders over $99, with quick processing from California and Texas distribution centers. **Ideal Applications:** Perfect for datacenter interconnects, enterprise network upgrades, high-speed LAN backbones, and storage area network (SAN) implementations requiring proven reliability and performance.
