OS2 MPO-12/APC 1-to-2 Breakout Cable

This OS2 single-mode breakout assembly converts one four-channel MPO-12/APC parallel-optics path into two two-channel MPO-12/APC branches for supported DR optical architectures. It is intended for longer rack-to-rack or row-to-row paths where the installed transceivers and channel loss budget call for single-mode fiber. The passive assembly does not independently determine data rate or reach.

Fiber type

OS2 single-mode, 9/125 µm

Fiber count

8 active fibers

Connector configuration

1 × MPO-12/APC female to 2 × MPO-12/APC female

Lane arrangement

One 4-channel side to two 2-channel branches
