Eaton N390B-40M-8AP 40 m OM4 8-Fiber MPO Cable

Extend an 8-fiber multimode MPO connection across 40 m with a 50/125 OM4 cable terminated in female MPO connectors at both ends. This MPO-to-MPO patch cable provides a defined interconnect for fiber paths that require an 8-fiber assembly rather than individual duplex jumpers. Its female-to-female connector arrangement is intended for mating with compatible MPO interfaces and adapters. N390B-40M-8AP specifies an APC MPO cable wired for Type B polarity. Polarity is a material selection detail in parallel-fiber cabling: the cable must match the polarity method used by the connected modules, cassettes, panels, or trunks. The 8-fiber construction also makes fiber count an explicit compatibility check before installation. Use this assembly where a 40 m cable length is required between MPO termination points in an OM4 multimode fiber path. Confirm the required connector gender, fiber count, APC interface requirement, polarity method, and 50/125 OM4 fiber type against the equipment and passive-fiber components at each end. Those details distinguish this cable configuration from MPO assemblies with different lengths, fiber counts, connector treatments, or polarity arrangements.
