The JBX67509 represents a premium solution for professional fiber optic networking needs. This 55-meter OM4 multimode cable combines cutting-edge technology with practical design to deliver exceptional performance in both indoor and outdoor environments. **Technical Excellence** Built on OM4 50/125 multimode fiber architecture, this cable provides superior bandwidth capacity and lower attenuation rates compared to standard OM3 alternatives. The bend-insensitive fiber construction ensures durability even in challenging installation scenarios, reducing the risk of signal degradation from sharp bends. With insertion loss specifications of ≤0.35dB (typical 0.15dB) and return loss ≥20dB, this cable maintains signal integrity across extended runs. **Safety & Compliance** The plenum-rated (OFNP) jacketing meets critical fire safety standards, making it suitable for installation in air handling spaces where standard PVC cables are prohibited. Full RoHS and ELV compliance ensures environmental responsibility, while TAA compliance supports government and institutional procurement requirements. US manufacturing guarantees quality control and supply chain reliability. **Performance Specifications** Attenuation rates of 3.5 dB/km at 850nm and 1.0 dB/km at 1300nm enable reliable transmission for high-speed applications including 10GbE and emerging 40GbE deployments. The LC/UPC connector termination provides excellent optical performance with minimal return loss. **Practical Design Features** The 5.0mm outside diameter accommodates standard cable management infrastructure, while the 18" furcated leg configuration simplifies routing and breakout applications. The 6-strand configuration offers flexibility for complex network topologies. **Applications** Ideally suited for data centers, enterprise campuses, telecommunications facilities, and multimedia installations. Perfect for applications requiring outdoor exposure combined with indoor performance standards. **Warranty & Support** Includes a 90-day limited warranty. Free standard shipping on orders over $99. Custom lengths available to match your exact installation requirements. Ships from convenient US locations in California and Texas.
