A Novel Framework for investing the electronic compensation for a 10.7-Gb/s system using a directly
modulated LASER (DML) approach. The significant usage of digital signal processing and large signal rate
equations helps in reducing the non linear distortion which outcomes from direct modulation of laser and to
generate an appropriate modulating current. After successful generation of modulation current the proposed
scheme is then utilized in a novel look up table optimization scheme for electronic dispersion precompensation.
Finally the simulation results shows that the proposed theoretical work shows the
compensation of 250km approximately using a 21.4GSa/s DIGITAL TO ANALOG CONVERTER and
simultaneously 350km approximately using a 42.8GSa/s DAC. Finally the proposed work shows that
approximately using a 42.8GSa/s DIGITAL TO ANALOG CONVERTER is sufficient forexploiting the full
potential for ELECTRONIC PRE-COMPENSATION using a DML.
