Eaton N390B-72M-8AP 72 m OM4 MPO-to-MPO Fiber Cable

Extend an MPO-based multimode fiber path by 72 m with an 8-fiber OM4 cable assembly terminated in female MPO connectors at both ends. The 50/125 µm multimode construction supports installations that standardize on OM4 fiber for high-bandwidth parallel-optics links, aggregation hardware, and structured-cabling runs. APC-polished MPO end faces provide the angled physical-contact interface specified for this assembly. Type B polarity is a material selection point: both ends must match the polarity method used by the installed trunks, cassettes, transceivers, or patching architecture. Verify the existing fiber polarity plan before introducing a Type B assembly into an MPO channel. Eaton N390B-72M-8AP is distinguished by its 72 m length, 8-fiber count, OM4 multimode rating, female-to-female MPO termination, APC polish, and Type B configuration. It is intended for a direct MPO-to-MPO fiber connection rather than copper Ethernet patching or duplex LC patching. The fixed 8-fiber construction helps match infrastructure that requires an eight-fiber MPO interface without adding unused positions from a larger-fiber-count cable.
