Adaptive preamble adjustment for burst-mode optical systems

Adaptive preamble adjustment for burst-mode optical systems

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 tran...

Zusammenfassung: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.
