Key Features

70 m fixed cable length
8-fiber OM4 50/125 µm multimode construction
Female MPO to female MPO connectivity
Type B polarity
APC-polished MPO interfaces
Connect 70 m multimode fiber paths with female MPO connectors at both ends.

Create a 70 m multimode fiber connection between MPO-equipped patching, cassettes, enclosures, or active equipment with an eight-fiber cable assembly. Eaton N390B-70M-8AP uses OM4 50/125 µm multimode fiber and female MPO connectors at both ends. Its 8-fiber construction matches applications that need an MPO interface without occupying the 12-fiber format commonly used for larger trunks. Type B polarity reverses the fiber positions from one end of the cable to the other. That polarity arrangement is a material selection point in MPO systems: the patch cable must match the polarity method used by the connected cassettes, trunks, and transceivers. The APC connector polish is likewise intended for mating with compatible angled-polish MPO interfaces rather than flat-polish connector faces. Use this cable where a 70 m fixed-length multimode segment is needed between compatible MPO endpoints. The female-to-female connector format requires mating interfaces with the corresponding guide-pin arrangement. Confirm fiber count, OM4 multimode media, Type B polarity, APC interface geometry, and the required 70 m route length before installation so the assembly matches the existing channel architecture.

Ideal For

Connecting compatible MPO patch panels across a 70 m multimode fiber route.
Extending an 8-fiber MPO channel between cassettes, enclosures, or equipment racks.
Completing Type B polarity paths that use APC MPO connector interfaces.

Why This Product

1Provides a 70 m fixed-length fiber run.
2Uses an 8-fiber MPO construction rather than a higher-fiber-count trunk format.
3Applies Type B end-to-end fiber position reversal.
4Uses female MPO connectors with APC-polished interfaces at both ends.

Frequently Asked Questions

How do I confirm N390B-70M-8AP is the right part for my deployment?▾

Confirm that both connection points accept female MPO cable ends and use compatible APC MPO interfaces. The channel must require 8-fiber OM4 50/125 µm multimode fiber, Type B polarity, and a 70 m cable length. Verify the polarity method across the complete MPO path.

What connector configuration does N390B-70M-8AP use?▾

This cable has a female MPO connector on each end, with APC-polished interfaces. Female MPO cable ends mate with corresponding guide-pin connector interfaces. Both endpoint hardware and any intermediate patching components must be compatible with MPO APC connections and the required fiber count.

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

Type B polarity reverses fiber positions from one cable end to the other. In an MPO channel, that reversal must align with the polarity arrangement used by connected trunks, cassettes, and transceiver connections. Select it when the complete path is engineered for Type B polarity.

Is this cable single-mode or multimode fiber?▾

The cable uses OM4 50/125 µm multimode fiber. It should be matched with compatible multimode MPO equipment and patching components. Do not substitute it for a single-mode fiber segment, because the fiber type, optical characteristics, and connected hardware requirements differ.
