ABSTRACT:
Dispersion compensation having a flat loss characteristic is performed. Overall wavelength dependence is made flat by using a passive device, such as a fiber Bragg grating having a transmission characteristic compensating for the wavelength dependent loss characteristic of a dispersion-compensating fiber, or an optical amplifier having a gain characteristic compensating for the wavelength dependent loss characteristics.
