| Abstract: | Normalized cut off frequency of fundamental mode in W Tunneling optical fiber is calculated Relationship between normalized cut off frequency and optical fiber structure parameter is analysed It is found that normalized cut off frequency is dependent only on refractive index depth of inner cladding when outer cladding of the fiber is far from core Correspondent approximate function and curve of normalized cut off frequency is prezented |

| Keywords: | W tunneling optical fiber cut off frequency approximate function |
