Eaton N390B-85M-8AP 85 m OM4 8-Fiber MPO APC Cable

Extend a multimode MPO fiber path across an 85 m distance with eight 50/125 µm OM4 fibers terminated in female MPO connectors at both ends. The APC connector treatment supports installations that call for angled-polish MPO interfaces, while the MPO-to-MPO format provides a direct patch-cable connection between compatible high-density fiber interfaces. N390B-85M-8AP uses Type B polarity. Polarity is a physical link-design requirement in MPO cabling: the cable’s specified Type B arrangement must match the polarity method used by the connected trunks, cassettes, modules, or equipment ports. Verify the end-to-end fiber path before installation, particularly where existing MPO infrastructure uses a different polarity method. The 8-fiber construction distinguishes this cable from higher-fiber-count MPO assemblies and matches applications built around eight-fiber optical paths. OM4 multimode fiber provides the specified fiber grade for premises and data-center cabling environments using 50/125 µm multimode infrastructure. Female MPO ends on both sides make connector gender an important compatibility check; confirm that the mating interfaces accept female MPO connectors and APC polish before routing the cable into a permanent pathway.
