Input fibers are matched to the pigtail fibers of customer laser diode sources. Normally, Input fibers are 100/125um multimode fibers with the numerical aperture of 0.15 or 0.22, and the output fiber ...

The MM-MC optical fiber is made of an array of 19 Yb-doped cores of 7 μm in diameter (0.065 numerical aperture (NA)) in a triangular lattice of 10.5 μm pitch covering a hexagonal section of ~50 ...
