Abstract :
An electronic dispersion precompensation scheme for a chirp-managed directly modulated laser is described and experimentally demonstrated for transmission at 10.709 Gb/s. A single look-up-table (LUT) for the drive current is designed to mitigate the effects of fiber dispersion and the intrinsic nonlinear modulation response of the laser. Experimental results show that an 11-bit LUT can compensate the dispersion of 608 km of a standard single-mode fiber with a required optical-signal-to-noise ratio of 14.5 dB at a bit-error ratio of 3.8 × 10-3.
