Key Features

45 m fixed cable length
8-fiber OM4 50/125 µm multimode fiber
Female APC MPO connectors on both ends
Type B MPO polarity
MPO-to-MPO connector configuration
Connect 8 multimode fibers through an MPO-to-MPO cable assembly.

Carry eight multimode optical fibers between MPO connection points over a fixed 45 m run. Eaton N390B-45M-8AP is an MPO-to-MPO fiber patch cable using OM4 50/125 µm multimode fiber, making it a defined interconnect for installations built around 8-fiber MPO cabling. Both cable ends use female MPO connectors with APC end faces. Type B polarity is a central selection detail for this cable. MPO polarity determines how transmit and receive fiber positions map from one end of a link to the other, so the cable must match the polarity method used by the connected patching, cassettes, or equipment interfaces. The 8-fiber construction also needs to match the fiber count of the MPO channel; it is not a general substitute for MPO assemblies built with a different fiber count. This assembly differs within the MPO patch-cable range through its combination of 45 m length, OM4 multimode construction, 8-fiber format, female APC MPO terminations, and Type B polarity. Use it where an installed pathway requires a longer preterminated MPO jumper rather than field termination. Confirm connector gender, APC interface requirements, polarity method, fiber count, and required cable length at both endpoints before installation.

Ideal For

Extending an 8-fiber OM4 MPO connection between fiber patching locations in a data room.
Connecting compatible MPO interfaces through a 45 m preterminated multimode pathway.
Replacing a Type B MPO jumper where female APC terminations are required at both ends.

Why This Product

1Provides a longer 45 m fixed-length option for MPO patching routes.
2Uses 8-fiber rather than a higher-fiber-count MPO format.
3Combines OM4 50/125 µm multimode fiber with female APC MPO ends.
4Uses Type B polarity for compatible MPO channel designs.

Frequently Asked Questions

What is included with N390B-45M-8AP?▾

N390B-45M-8AP specifies a 45 m MPO-to-MPO multimode fiber patch cable with 8 OM4 50/125 µm fibers. Both ends use female APC MPO connectors, and the cable has Type B polarity. It is a passive cable assembly rather than an active optical component or transceiver.

What connectors does the Eaton N390B-45M-8AP use?▾

The cable has female MPO connectors at both ends, with APC end faces. Its connector arrangement is MPO to MPO, so both connected endpoints must accept the cable's MPO connector gender and APC interface style.

What does Type B polarity mean for this MPO cable?▾

Type B identifies the MPO polarity method used by the cable. Polarity controls how fiber positions map from one end of an MPO link to the other. Match this cable to the polarity method used by the connected patching components and equipment interfaces.

Where does an 8-fiber OM4 MPO patch cable fit?▾

Use an 8-fiber OM4 MPO patch cable where both endpoints require an MPO interconnect with eight 50/125 µm multimode fibers. Confirm the required 45 m route length, connector gender, APC requirement, fiber count, and Type B polarity before connecting it.
