Key Features

78 m cable length for extended structured-fiber runs
8-fiber OM4 50/125 µm multimode construction
Female MPO connectors at both cable ends
APC connector finish on both MPO terminations
Type B MPO polarity
Connect 8 OM4 50/125 µm multimode fibers through one 78 m MPO-to-MPO cable assembly.

Carry eight multimode fibers through a single 78 m MPO-to-MPO patch cable rather than routing individual duplex jumpers. The OM4 50/125 µm construction supports high-density fiber pathways where space, cable count and connector density matter. Female MPO connectors at both ends provide an MPO interface on each side of the run, while APC end-face geometry is specified for both connector ends. Type B polarity is the defining connection arrangement for this assembly. Match the cable to equipment, cassettes and patching hardware that call for an 8-fiber Type B MPO path; polarity must remain consistent across the complete channel. The eight-fiber count makes this cable a focused option for parallel-fiber infrastructure rather than a general-purpose duplex patch lead. Eaton N390B-78M-8AP fits structured multimode fiber runs that need a long, pre-terminated MPO connection between compatible distribution points. Confirm the required fiber count, OM4 multimode media, female MPO interfaces, APC connector finish and Type B polarity before installation. Its 78 m length suits links extending beyond short rack-to-rack patching while retaining a single integrated cable assembly.

Ideal For

Long multimode MPO trunk between fiber distribution locations in a data center row.
High-density 8-fiber patch path between compatible MPO cassettes or panels.
Structured cabling run requiring OM4 multimode fiber with Type B polarity.

Why This Product

1Provides a 78 m reach for longer MPO fiber paths.
2Uses 8 fibers rather than a duplex fiber layout.
3Combines OM4 50/125 µm multimode fiber with female APC MPO ends.
4Uses Type B polarity for channels built around that polarity method.

Frequently Asked Questions

What is included with N390B-78M-8AP?▾

N390B-78M-8AP is a single 78 m fiber patch cable assembly with eight OM4 50/125 µm multimode fibers. It has female APC MPO connectors at both ends and uses Type B polarity.

What connector configuration does this MPO cable use?▾

Both cable ends use female MPO connectors with APC end-face geometry. The cable is MPO-to-MPO, so each connected device, panel or cassette must present a compatible MPO interface and connector arrangement.

What does Type B polarity mean for this cable?▾

Type B identifies the MPO polarity arrangement of the eight-fiber cable. Use it only in a channel planned for Type B polarity, including the associated MPO hardware, to preserve the intended fiber mapping end to end.

Where does a 78 m OM4 MPO cable fit?▾

A 78 m assembly fits extended multimode structured-cabling paths between compatible MPO distribution points. It can reduce the number of intermediate cable joins where a single pre-terminated eight-fiber route is required.
