Abstract
A system and method for reducing power consumption in a Passive Optic Network (PON). The system comprises an optical line terminal (OLT), an optical network unit (ONU), a traffic-detection module configured to detect status of traffic to and from the ONU, and a power-management module configured to place the ONU in sleep mode based on the detected traffic status. The ONU includes transmitting and receiving components that are selectively powered down during the sleep mode based on a type of traffic in the ONU.
Claims20
A system comprising:
- an optical network unit (ONU) configured to operate in a first mode or a second mode of operation;
- an optical line terminal (OLT) coupled to the ONU, the OLT being configured to:
- instruct the ONU to operate in the first mode of operation based on a type of traffic in upstream traffic or downstream traffic;
- buffer the downstream traffic to the ONU during the first mode of operation;
- and
- disable a queue for the downstream traffic during the first mode of operation, the queue being located in the OLT.

A method comprising:
- operating an optical network unit (ONU) in a first mode or a second mode of operation;
- instructing the ONU, using an optical line terminal (OLT), to operate in the first mode of operation based on a type of traffic in upstream traffic or downstream traffic;
- buffering the downstream traffic to the ONU during the first mode of operation;
- and
- disabling a queue for the downstream traffic during the first mode of operation, the queue being located in the OLT.
2 more elements
A system comprising:
- a first network equipment;
- and
- a second network equipment coupled to the first network equipment, the second network equipment being configured to:
- enable a first mode or a second mode of operation of the first network equipment based on a status of traffic;
- buffer downstream traffic to the first equipment during the first mode of operation;
- and
- disable a queue for the downstream traffic during the first mode of operation.
