Description
The Eaton N858B-38M-3X8MG is a premium 40/100 GbE multimode 50/125 OM4 fiber optic cable designed for high-density enterprise and data-center environments. Engineered for superior performance and bandwidth, this 38-meter (124.7 ft.) cable supports transmission speeds up to 400 Gb Ethernet across short distances, ensuring reliable connectivity for cloud services, hyperscale data centers, and telecom infrastructures.
Featuring a magenta LSZH (Low-Smoke Zero-Halogen) jacket, the cable allows easy identification in crowded racks while minimizing toxic smoke emissions during combustion—ideal for poorly ventilated installations. The 3×8-fiber MTP/MPO-PC connectors enable efficient trunking, quick deployment, and seamless scalability from 10 Gb to 400 Gb networks. Backward compatibility ensures investment protection for future network upgrades.
