Eaton N390B 65 m OM4 8-Fiber MPO APC Cable

Carry eight multimode fibers between compatible MPO optical interfaces over a 65 m run. Eaton N390B-65M-8AP uses OM4 50/125 µm multimode fiber with female MPO connectors at both ends. Its APC connector polish and Type B polarity define the required optical interface arrangement, so the connected equipment and installed cabling must use the corresponding MPO format. This patch cable fits structured multimode fiber trunks between patching fields, MPO cassettes, and active equipment with compatible MPO interfaces. The 65 m factory-terminated assembly spans longer equipment-room or data-center routes without adding an intermediate MPO coupler solely to extend the path. Female MPO ends mate with compatible male MPO interfaces, making connector gender a direct installation consideration at both endpoints. Within the N390B cable range, this configuration is defined by its 65 m length, 8-fiber construction, OM4 multimode fiber, APC polishing, and Type B polarity. The 50/125 µm fiber geometry identifies it for OM4 multimode infrastructure rather than single-mode cabling. Type B polarity is a specific MPO arrangement and should remain consistent through cassettes, trunks, and equipment connections in the complete optical channel.
