Key Features

19 m fixed cable length
8 x OM4 50/125 µm multimode fibers
Female MPO to female MPO, APC-polished
Type B polarity
Connect 8 multimode fibers through a 19 m preterminated MPO-to-MPO patch path.
Match OM4 50/125 µm multimode fiber infrastructure with an 8-fiber cable assembly.

Connect MPO-equipped multimode equipment with an eight-fiber patch lead that maintains a fixed 19 m path between female MPO ports. Eaton N390B-19M-8AP combines OM4 50/125 µm multimode fiber with female-to-female MPO terminations, giving installers a single preterminated cable for an 8-fiber link rather than individual duplex jumpers. Its APC connector polish must match MPO interfaces specified for APC mating. Type B polarity reverses the fiber-position sequence from one end to the other. That mapping matters when the connected optics, cassettes, or trunks expect a Type B channel assignment; polarity is an end-to-end link characteristic, not a cosmetic connector detail. Verify that mating interfaces are female MPO and that their polarity method calls for a Type B, APC 8-fiber assembly. Use the 19 m length where equipment rows, cabinets, or distribution points require a measured MPO patch path without adding a coupler. OM4 multimode construction suits multimode optical cabling environments, while the 8-fiber format keeps the assembly aligned to MPO systems built around eight active fibers. This cable does not convert connector type, fiber mode, polish, or polarity; both ends remain female MPO APC.

Ideal For

MPO patching between multimode optical equipment with female MPO APC interfaces.
19 m equipment-row or cabinet-to-distribution-point multimode fiber runs.
8-fiber MPO links that require Type B polarity mapping.

Why This Product

1Provides a fixed 19 m cable length for longer MPO patch paths.
2Uses 8-fiber OM4 50/125 µm multimode construction.
3Terminates both ends with female MPO connectors using APC polish.
4Uses Type B polarity for reversed fiber-position mapping.

Frequently Asked Questions

What is included with Eaton N390B-19M-8AP?▾

Eaton N390B-19M-8AP supplies one 19 m preterminated multimode fiber patch cable. Both ends use female MPO connectors with APC polish, and the assembly contains eight OM4 50/125 µm multimode fibers arranged with Type B polarity.

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

Type B polarity reverses the fiber-position sequence between the two cable ends. It must match the polarity method used by the connected MPO optics, cassettes, trunks, or patching hardware so transmit and receive paths align correctly.

What connector interfaces does N390B-19M-8AP require?▾

This cable has female MPO connectors at both ends with APC polish. The connected equipment or cabling components must provide compatible MPO APC mating interfaces and support the cable's 8-fiber format and Type B polarity arrangement.

When should I choose a 19 m MPO patch cable?▾

Choose a 19 m cable when the measured path between MPO connection points requires that length without an intermediate coupler. Confirm routing allowance, connector gender, APC polish, fiber mode, fiber count, and polarity before installation.
