In this letter we describe the use of tunable chromatic dispersion compensator based on chirped fiber Bragg grating to improve the performance of a 10 Gbit/s optical fiber communication system. Tunable compensation is achieved by applying temperature gradients along the grating longitudinal axis. It is demonstrated that thermal gradients comprised between −40 and 40°C were able to change the grating dispersion from −84.88 to −218.30 ps/nm. Previously developed model that issued a BER variation on the system from 1.82 × 10 −12 to 1.62 × 10 −9 are consistent with the experimental evidences reported here. © 2006 Wiley Periodicals, Inc.
