Key Features

20 m OS2 8.3/125 µm single-mode fiber construction
1 x 8-fiber APC MPO female input
2 x 4-fiber breakout branch topology
8-fiber-to-two-branch fiber distribution
Split one 8-fiber APC MPO female connection into two 4-fiber breakout branches.

Route a single-mode fiber path from one 8-fiber APC MPO female connection to two separate 4-fiber branches. The 1-to-2 breakout topology helps organize fiber distribution where an 8-fiber trunk-side connection must divide toward separate downstream paths without adding a separate breakout assembly. The cable uses OS2 8.3/125 µm single-mode fiber and provides a 20 m reach between connection points. Its APC MPO female input is suited to fiber environments where APC-polished MPO interfaces are already defined at the trunk or distribution side. The two breakout branches each carry 4 fibers, preserving a clear physical division of the original 8-fiber path. Eaton N390B-20M-1X2AP is differentiated within the N390B cable range by its 20 m length, single-mode OS2 construction, 8-fiber APC MPO female input, and two-way 4-fiber breakout format. Match the required cable reach, source-side MPO interface, fiber count, and branch topology before selecting it for a fiber cross-connect, distribution frame, or equipment-area installation.

Ideal For

Fiber distribution frames that divide one 8-fiber single-mode MPO path into two 4-fiber routes.
Data center equipment areas requiring a 20 m OS2 breakout run between trunk-side and downstream fiber paths.
Structured cabling installations using APC MPO female connectivity on the 8-fiber source side.

Why This Product

1Provides a 20 m reach for longer single-mode fiber paths.
2Uses one 8-fiber APC MPO female input connection.
3Divides the input into two separate 4-fiber branches.
4Uses OS2 8.3/125 µm single-mode fiber rather than multimode fiber.

Frequently Asked Questions

How do I confirm N390B-20M-1X2AP is the right part for my deployment?▾

Confirm that the installation needs a 20 m OS2 8.3/125 µm single-mode cable with one 8-fiber APC MPO female input and two 4-fiber breakout branches. Verify the required source-side MPO interface, fiber count, branch topology, and cable route length.

What does the 1 x 8-fiber to 2 x 4-fiber configuration mean?▾

The cable accepts one 8-fiber connection at its APC MPO female input and divides that fiber path into two physical branches. Each breakout branch carries 4 fibers, allowing one incoming 8-fiber path to be routed toward two separate downstream paths.

What fiber type does this breakout cable use?▾

This cable uses OS2 single-mode fiber with an 8.3/125 µm core and cladding specification. OS2 construction is used for single-mode structured fiber routes where the installed cable plant and connected optical equipment require single-mode fiber.

What connector is provided on the 8-fiber input side?▾

The 8-fiber input side uses an APC MPO female connector. Match the existing trunk-side or distribution-side connection to an APC MPO female interface and ensure the required fiber count and connector arrangement align with the cable's 8-fiber input format.
