1. A method of making a core configuration transformer, comprising:
splicing a first end of a length of coreless optical fiber to a first end face of a first multicore optical fiber including a first plurality of cores that define a first end face core pattern at the first end face;
splicing a second end of the length of coreless optical fiber to a second end face of a second multicore optical fiber including a second plurality of cores that define a second end face core pattern at the second end face different from the first end face core pattern; and
defining a transforming optical fiber by writing a plurality of routing cores in the length of coreless optical fiber each configured to operatively couple a respective core of the first plurality of cores to a respective core of the second plurality of cores.
