Key Features

39 m fixed cable length
OS2 singlemode 8.3/125 µm fiber
1 x 8-fiber APC MPO female to 2 x 4-fiber breakout
8-fiber trunk split into two 4-fiber legs
Split 1 x 8-fiber path into 2 x 4-fiber breakout legs.
Route singlemode OS2 fiber across a 39 m fixed-length cable run.

Route an 8-fiber singlemode path from one APC MPO female connection to two separate 4-fiber legs with this 39 m breakout assembly. The cable uses OS2 fiber with an 8.3/125 µm core/cladding specification, making it suited to singlemode optical cabling runs where fiber count must be divided at the cable level rather than through a separate breakout component. The one-to-two construction provides one 8-fiber MPO interface at the trunk end and two 4-fiber ends at the breakout end. This arrangement can simplify routing where an 8-fiber backbone must serve two smaller fiber paths, including rack-to-rack runs, patching areas, and equipment locations with separate 4-fiber connections. The 39 m length supports installations that need a defined cable route without field termination. Eaton N390B-39M-1X2AP combines a singlemode OS2 construction with an APC MPO female trunk-side connector and an 8-fiber-to-dual-4-fiber topology. Those details distinguish it from straight-through MPO assemblies and from breakout cables built around other fiber counts or connector arrangements. Maintain the specified polarity and connector-interface requirements across the complete optical channel when planning the connection path.

Ideal For

Splitting an 8-fiber singlemode backbone into two 4-fiber runs within a data center.
Routing an MPO-based trunk from a patching area to separate four-fiber equipment paths.
Installing a pre-terminated 39 m OS2 fiber route between racks or telecommunications spaces.

Frequently Asked Questions

What is included with N390B-39M-1X2AP?▾

N390B-39M-1X2AP is a 39 m pre-terminated singlemode OS2 fiber breakout cable. It has one 8-fiber APC MPO female connection at the trunk end and divides into two 4-fiber ends at the breakout end.

What fiber configuration does this cable provide?▾

The assembly converts one 8-fiber path into two separate 4-fiber legs. Its trunk-side interface is an 8-fiber APC MPO female connector, while the opposite side provides two 4-fiber breakout ends for connection into the planned optical cabling path.

Is this an OS2 singlemode fiber cable?▾

Yes. The cable uses OS2 singlemode fiber with an 8.3/125 µm core/cladding specification. It is intended for singlemode optical infrastructure rather than multimode fiber channels, so the connected equipment and cabling path should use compatible singlemode interfaces.

When is an 8-fiber to dual 4-fiber breakout cable useful?▾

Use this topology when one 8-fiber backbone route must branch into two smaller 4-fiber routes. It can reduce intermediate breakout hardware in a structured cabling path while retaining a single pre-terminated MPO connection at the trunk side.
