Double-clad fiber is single-mode

Because double-clad fiber propagates both single mode and multimode light, it can be spliced to either single mode or multimode fiber with a low splice loss (

Double-clad fiber

Double-clad fiber (DCF) is a class of optical fiber with a structure consisting of three layers of optical material instead of the usual two. The inner-most layer is called the core. It is surrounded by the inner cladding, which is surrounded by the outer cladding. The three layers are made of materials with different refractive indices. There are two different kinds of double-clad fibers. The first was developed early in o
