1. A process for coupling optic fibers, the process comprising:
receiving three multicore fibers, each of the multicore fibers comprising four cores surrounded by a cladding, whereby twelve total cores of the multicore fibers are present;
for each of the three multicore fibers, coupling the multicore fiber with a transition portion by coupling with an adaptor of the transition portion, whereby three adaptors are present;
for each of the three adaptors, coupling the adaptor with four individual single core fibers, whereby twelve individual single core fibers are present;
coupling the twelve individual single core fibers with a transition part of the transition portion; and
coupling the transition part of the transition portion with an individual ribbon having twelve cores such that the twelve cores of the individual ribbon are coupled for respective transmission of signals through the twelve total cores of the multicore fibers.
