Eaton N390B-75M-8AP 75 m OM4 8-Fiber MPO Cable

Provide an eight-fiber multimode connection between MPO-equipped panels, cassettes, or active equipment across a 75 m run. Eaton N390B-75M-8AP uses OM4 50/125 µm fiber and female MPO connectors at both ends, making it a direct cable assembly for installations built around MPO interfaces. Its eight-fiber construction suits parallel-fiber pathways that require all positions carried in one trunk. Type B polarity establishes a reversed fiber-position mapping from one end of the assembly to the other. That polarity must match the cassettes, transceivers, and patching architecture used on the link; it is a physical connectivity characteristic, not a field-configurable setting. APC-polished MPO end faces further identify the connector treatment required when mating the cable to compatible APC MPO interfaces. This 75 m configuration addresses long in-room, row-to-row, or facility fiber paths without joining shorter assemblies. Select it where the installed channel calls specifically for OM4 multimode fiber, eight fibers, female-to-female MPO terminations, Type B polarity, and APC polishing. Verify the mating interface and polarity plan at both endpoints before routing the cable, since an MPO connection depends on the complete channel arrangement.
