Abstract
The invention relates to a dispersion-shifted single-mode optical fiber having an effective area greater than or equal to 60 &mgr;m . This fiber is characterized by the fact that it has a zero chromatic dispersion wavelength &lgr; lying in the range 1400 nm to 1480 nm, and bending losses of less than 0.05 dB at 1550 nm for a winding of 100 turns of the fiber around a radius of 30 mm. The invention is applicable to wavelength division multiplexed transmission systems, and makes it possible to limit non-linear effects, such as four-wave mixing, and to limit the use of dispersion-compensating fiber.
