摘要：

Properties of doubly-clad optical fibers with a low-index inner cladding (W-type fibers) as single-mode or multimode transmission lines are discussed both from theoretical and experimental viewpoints. Such fibers are characterised by the tight confinement of the modal power in the core. A small bending loss is one of its consequences. A single-mode W-type fiber can be used at a v-value significantly larger than 2. 405, and it has an anomalous dispersion effect. A multimode W-type fiber is also discussed.
