Abstract
An apparatus comprising an individual optical power level calculation (IOPLC) module and a transceiver coupled to the IOPLC module and configured to communicate with a plurality of optical network units (ONUs). Also disclosed is an apparatus comprising a control and management (CM) module, an average power level measurement (APLM) module coupled to the CM module, a first transceiver coupled to the CM module and configured to communicate with an optical line terminal (OLT), and a second transceiver coupled to the CM module and the APLM module, and configured to communicate with a plurality of ONUs.
Claims17
A reach extender comprising:
- an upstream signal regenerator;
- and
- a measurement circuit configured to generate a series of measurements of time averaged received upstream optical signal power from one or more optical network units (ONUs), wherein the measurement circuit has a temporal response similar to a low pass filter,
- wherein the reach extender is configured to report the series of measurements to an optical line terminal (OLT), and
- wherein the reach extender is located between the one or more ONUs and the OLT.
A method comprising:
- regenerating signals from one or more optical network units (ONUs) in the upstream direction to an optical line terminal (OLT);
- generating a series of measurements of time averaged received upstream optical signal power from the one or more ONUs, wherein the measurements are generated similar to a low pass filter, and
- reporting the series of measurements to the OLT.
A reach extender comprising:
- an optical-electrical-optical (OEO) amplifier configured to perform OEO regeneration in an upstream direction;
- and
- a measurement circuit configured to generate the series of measurements, wherein the measurement circuit has a temporal response similar to a low pass filter,
- wherein the reach extender is configured to report a series of measurements of time averaged received upstream optical signal power from one or more optical network units (ONUs), and
- wherein the reach extender is located between the one or more ONUs and an optical line terminal (OLT).
