Abstract
An OLT includes an ONU link state monitor that monitors a registered state of each of the ONUs, a continuous light-emission monitor that detects a continuous light-emitting state on the basis of a monitor result given by the ONU link state monitor, and identifies an ONU being in continuous light-emission, and an optical output power shut down command unit that commands the ONU identified by the continuous light-emission monitor to shut down the optical output power. Each of the ONU includes an optical transmitter and receiver device that transmits and receives an optical signal to/from the OLT, and a light output controller that shuts down light of the optical transmitter and receiver device in response to the command given by the optical output power shut down command unit.
Claims8
A PON system comprising:
- an OLT;
- and
- a plurality of ONUs connected to the OLT,
- wherein the OLT includes:
- an ONU link state monitor that monitors a registered state of each of the ONUs;
- a continuous light-emission monitor that detects a continuous light-emitting state on the basis of a monitor result given by the ONU link state monitor, and identifies an ONU being in continuous light-emission;
- and
- an optical output power shut down command unit that commands the ONU identified by the continuous light-emission monitor to shut down the optical output power, and
- wherein the ONU includes:
- an optical transmitter and receiver device that transmits and receives an optical signal to/from the OLT;
- and
- a light output controller that shuts down light of the optical transmitter and receiver device in response to the command given by the optical output power shut down command unit.
An OLT which is connected to a plurality of ONUs, the OLT comprising:
- an ONU link state monitor that monitors a registered state of each of the ONUs;
- a continuous light-emission monitor that detects a continuous light-emitting state on the basis of a monitor result given by the ONU link state monitor, and identifies an ONU being in continuous light-emission;
- and
- an optical output power shut down command unit that commands the ONU identified by the continuous light-emission monitor to shut down the optical output power.
An ONU which is connected to an OLT, the ONU comprising:
- an optical transmitter and receiver device that transmits and receives an optical signal to/from the OLT;
- and
- a light output controller that shuts down light of the optical transmitter and receiver device in response to a command based on detection/identification of continuous light-emission on the basis of a registered state of the ONU itself given by the OLT.
