Optical chromatic dispersion compensation is achieved by analog predistortion of the signal in the microwave domain exploiting at the transmitter a chirped delay line. We designed a microwave device that guarantees high compactness of the solution and increased performance in terms of uncompensated propagation reach. Error-free, 10-Gb/s transmission over 225 km of uncompensated fiber is experimentally demonstrated without the use of coherent detection, digital equalizers, or optical dispersion compensators.

Abstract

Optical chromatic dispersion compensation is achieved by analog predistortion of the signal in the microwave domain exploiting at the transmitter a chirped delay line. We designed a microwave device that guarantees high compactness of the solution and increased performance in terms of uncompensated propagation reach. Error-free, 10-Gb/s transmission over 225 km of uncompensated fiber is experimentally demonstrated without the use of coherent detection, digital equalizers, or optical dispersion compensators.
