How many cores does a multimode pigtail have
The transition between the core and cladding can be sharp, which is called a, or a gradual transition, which is called a. The two types have different dispersion characteristics and thus different effective propagation distances. Multi-mode fibers may be constructed with either or Multimode fiber pigtails have a larger core— 50 μm or 62. Multimode fibers are fibers having multiple guided modes at the operating wavelength — sometimes only a few (→ few-mode fibers), but often many.
