Eaton N390B-84M-8AP 84 m OM4 8-Fiber MPO Cable

Carry eight optical fibers between compatible MPO interfaces across an 84 m run. Eaton N390B-84M-8AP uses OM4 50/125 µm multimode fiber with MPO connectors at both ends. Both connector ends are female and APC terminated, providing a defined MPO-to-MPO interface for fiber patching instead of separate fan-out connections. Type B polarity reverses fiber positions from one cable end to the other. This matters where the installed link polarity method requires an end-to-end fiber-position reversal. Match the cable's 8-fiber count, female MPO interfaces, APC termination, and Type B polarity to the cassettes, panels, adapters, or equipment ports used in the installed fiber path. Use this assembly for fixed-length MPO interconnects in equipment rooms, cross-connect areas, and multimode structured-cabling runs that need an 84 m cable span. The combination of OM4 multimode fiber, 8-fiber construction, female APC MPO ends, and Type B polarity distinguishes this configuration from MPO assemblies with different fiber counts, connector interfaces, termination geometry, or polarity methods. A continuous 84 m cable can also avoid intermediate joins where a single run is appropriate.
