Eaton N390B-20M-8AP 20 m OM4 MPO-to-MPO Fiber Cable

Provides a 20 m multimode fiber path between MPO-equipped endpoints using 8-fiber OM4 50/125 µm construction. Eaton N390B-20M-8AP terminates both ends with female MPO connectors and uses APC polish, making it a defined cable option where the installed link calls for angled physical-contact MPO interfaces rather than flat-polish connectors. Type B polarity reverses fiber positions from one end of the cable to the other. That mapping matters in parallel-optics channel layouts, where transmit and receive lanes must arrive at the corresponding positions on the far-end equipment, cassette, or patching assembly. The cable’s eight-fiber format suits links that use an eight-fiber MPO interface instead of a 12-fiber trunk arrangement. OM4 multimode fiber is specified for short-reach, high-bandwidth optical connections within data centers, equipment rooms, and campus backbone spaces. The 20 m length provides reach between adjacent racks, rows, or fiber distribution points without adding an intermediate coupler. Verify that both connected MPO interfaces require female connectors, APC polish, eight fibers, and Type B polarity before installation; those interface details determine whether the cable maps correctly in the optical path.
