A system, method, and computer readable medium comprising instructions for rogue Optical Network Unit (ONU) detection by analyzing the frequency content are provided. Once an optical signal is received from an optical network unit, the transition detection unit converts the optical signal to an electrical data signal. The transition detection unit then analyzes the electrical data signal to determine a presence of the rogue optical network unit. To determine presence of a rogue ONU, the transition detection unit may digitally oversample the data, filter the data with a high pass filter or measure the received signal strength.
