This paper proposes the technique of compensating fiber on various numbers of channels by altering the bandwidth. By applying the filter we try to consume the energy to the extent as much as possible. We observe that the average energy consumption before filtering remains constant but as soon as on applying the filter the average energy consumption starts altering. Even the group delay remains constant for same bandwidth but as the value of bandwidth is increased the group delay drops off. The mathematical model is derived for the filter. Simulation tool MATLAB is used to verify the results. Keywords: Average Energy Consumption, Bandwidth Utilization, Compensating Fiber, Group Delay, Passive Optical Networks
