Eaton N390B 18 m OM4 8-Fiber MPO APC Type B Cable

Connect MPO-equipped optical equipment across an 18 m run with an 8-fiber OM4 multimode patch cable built for female-to-female MPO connections. Eaton N390B-18M-8AP uses 50/125 µm multimode fiber and APC MPO connector interfaces at both ends. Its 8-fiber construction supports installations that use parallel-fiber MPO connectivity rather than individual duplex patch leads. Type B polarity is a defining selection point for this cable. MPO polarity determines the fiber mapping through a link, so the patch cable must match the polarity method established by the installed trunks, cassettes, patch panels, and equipment interfaces. This assembly provides Type B polarity for environments where that mapping is required. The female connector format also matters: both ends are specified as female MPO, allowing the cable to mate with corresponding pinned MPO interfaces. Select this N390B cable when the path requires OM4 50/125 µm multimode fiber, eight optical fibers, APC MPO terminations, and an 18 m reach. It fits structured fiber patching between equipment, distribution areas, and MPO-based optical assemblies where connector gender and polarity must remain consistent through the complete channel.
