1. A multi-core fiber (MCF) (100) comprising:
a plurality of cores (102), wherein each core is associated with a core diameter (104) and a core-placement-radius (106); and
a marker (108), wherein the marker (108) is associated with a marker diameter (110) and a marker-placement-radius (112), wherein the marker diameter (110) is equal to a core diameter (104), wherein the marker-placement-radius (112) is different from the core-placement-radius (106), wherein the marker (108) has a marker core (116) and a marker clad (118), wherein a first ratio of the clad diameter to core diameter of the marker (108) is greater than a second ratio of clad diameter to core diameter of the plurality of cores (102).
