Abstract: In an optical data network, such as a passive optical network (PON), an optical line terminator (OLT) measures the strengths of one or more signals received from the optical network units (ONUs) and generates a message containing an indication responsive to the measured signal strength. The OLT transmits the message to the ONUs. The ONUs generate packets having preambles of a length responsive to the indication contained in the message.

Abstract: In a passive optical network (PON), a burst-mode receiver of an optical line terminator (OLT) is initialized during an initialization phase, such as ranging, by asserting one or more reset signals in response to detecting the presence of a packet signal. For example, after the OLT transmits an initialization message, such as a ranging grant, to an optical network unit (ONU), it asserts one or more reset signals when it detects the presence of a packet signal received from the ONU in response.

Abstract: 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.
