Optical fibre having low mode dispersion |
摘要 |
An optical fibre has a core and a plurality of rings surrounding the core. In one arrangement the core and subsequent alternate rings are light transmitting, while the intermediate rings are of cladding material. In an alternative arrangement the core and alternate rings are of cladding material and intermediate rings are light transmitting. The light transmitting rings can be of varying refractive index or of constant refractive index.
