Eaton N390B-90M-8AP 90 m OM4 8-Fiber MPO Fiber Cable

Carry parallel optical channels across a 90 m structured-fiber run with an OM4 multimode MPO trunk using eight 50/125 µm fibers. Eaton N390B-90M-8AP terminates in female MPO connectors at both ends, providing an MPO-to-MPO connection for infrastructure that requires an 8-fiber APC assembly. The cable provides a fixed-length backbone connection rather than a copper Ethernet patch lead. Each MPO end uses APC polishing, which pairs with compatible angled-polish MPO interfaces. Female MPO connector faces do not contain alignment pins, so connector gender must match the mating port or adapter. Type B polarity reverses fiber positions from one end of the trunk to the other. That polarity arrangement matters when linking patch panels, cassettes, and parallel-optics equipment that have been planned around Type B fiber mapping. This configuration combines OM4 50/125 µm multimode fiber, 8-fiber construction, APC connector interfaces, Type B polarity, and a 90 m length. Select it where both endpoints specifically require female MPO connections and the installed link plan calls for an 8-fiber Type B trunk. Match the connector polish, gender, polarity method, fiber count, and required path length before installation to preserve the intended optical path.
