Eaton N390B-79M-8AP 79 m OM4 MPO APC Fiber Cable

Carry eight multimode fibers between compatible MPO interfaces across a 79 m route. Eaton N390B-79M-8AP uses OM4 50/125 µm fiber and female MPO connectors at both ends, providing a preterminated MPO-to-MPO connection rather than requiring individual fibers to be terminated in the field. APC end faces are specified on both connector ends for installations that require angled-polish MPO connectivity. Type B polarity makes this assembly a defined polarity choice for parallel-fiber paths. The eight-fiber construction matches equipment and patching arrangements built around eight-fiber MPO connectivity; verify the required polarity scheme at both endpoints before routing the cable. Its 79 m length addresses longer cross-row, row-to-row, or room-scale cable paths while retaining one continuous preterminated assembly and avoiding intermediate splice work along the route. Use the cable between compatible MPO interfaces where OM4 multimode fiber, APC polish, female connector gender, and Type B polarity are all required. Route it with adequate pathway capacity and bend protection, and keep MPO end faces protected until final mating. The 79 m length, eight-fiber count, OM4 fiber grade, APC connectors, and Type B polarity distinguish this configuration from MPO cable assemblies with different optical media, polarity methods, connector finishes, or reach.
