Core polarity invariant structured multicore fiber optic cabling system

A breakout module for a structured multicore fiber optic cabling system, comprising:

• a plurality of multicore optical fibers each including a first end face having a first end face core pattern and a second end face having a second end face core pattern that is a mirror-image of the first end face core pattern, the plurality of multicore optical fibers being configured so that a first half thereof has a first draw direction and a second half thereof has a second draw direction opposite the first draw direction,
• a trunk connector including a trunk connector interface configured so that the first end face of each multicore optical fiber having the first draw direction and the second end face of each multicore optical fiber having the second draw direction is placed in the trunk connector interface to define a first connector core pattern having a first mirror-image symmetry;
• and
• a plurality of branch connectors each including a branch connector interface and being operatively coupled to the trunk connector by a respective multicore optical fiber from each of the first and second halves of the plurality of multicore optical fibers,
• wherein each branch connector is configured so that the second end face of the multicore optical fiber having the first draw direction and the first end face of the multicore optical fiber having the second draw direction is placed in the branch connector interface to define a second connector core pattern having a second mirror-image symmetry.
