ABSTRACT:
A multi core optical fiber made of quartz glass comprising at least two cores the centers of which are arranged substantially on one line. The distances between the centers of the adjacent cores are substantially the same in the longitudinal direction. A first cladding covers the cores and the second cladding covers the first cladding and has a larger refractive index than the first one. The fiber has improved mechanical strength and low cross-talk even if the distance between the adjacent cores is short.
