Abstract
A stepped index optical fiber is disclosed having a chromatic dispersion cancellation wavelength less than 1 280 nm or even 1 250 nm. The fiber can be used for wavelength-division multiplex transmission not only in the window around 1 550 nm but also in the window around 1 300 nm. The chromatic dispersion in the second window enables transmission without excessively penalizing non-linear effects. A fiberoptic transmission system which uses the above fiber as line fiber is also disclosed.
