1. A structured multicore fiber optic cabling system, comprising:
one or more multicore fiber optic cable assemblies each including:
a first cable connector including a first cable connector interface,
a second cable connector including a second cable connector interface, and
a first 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 first plurality of multicore optical fibers 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,
wherein the first cable connector is 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 first cable connector interface to define a first connector core pattern having a first mirror-image symmetry, and
wherein the second cable connector is configured so that the first end face of each multicore optical fiber having the second draw direction and the second end face of each multicore optical fiber having the first draw direction is placed in the second cable connector interface to define the first connector core pattern; and
a plurality of network components each including a port connector having a port connector interface including a plurality of end faces with a first half thereof having the first end face core pattern and a second half thereof having the second end face core pattern, each end face of the plurality end faces being placed in the port connector interface to define the first connector core pattern,
wherein core polarity is preserved between a first port connector of a first network component of the plurality of network components and a second port connector of a second network component of the plurality of network components:
when the first cable connector of a first multicore fiber optic cable assembly of the one or more multicore fiber optic cable assemblies is operatively coupled to the first port connector, and the second cable connector of the first multicore fiber optic cable assembly is operatively coupled to the second port connector, and
when the first cable connector of the first multicore fiber optic cable assembly is operatively coupled to the second port connector, and the second cable connector of the first multicore fiber optic cable assembly is operatively coupled to the first port connector.
