Patent ID: 7957650

Claim:
A pluggable optical network unit, comprising: a transceiver assembly configured to produce a first electrical signal in response to a first optical signal and to emit a second optical signal in response to a second electrical signal, wherein the first optical signal comprises reception signal data, wherein the second optical signal comprises transmission signal data; a data processing unit in communication with the transceiver assembly, wherein the data processing unit is configured to extract the reception signal data from the first electrical signal and produce the second electrical signal in response to the transmission signal data; an interface unit configured to receive the reception signal data from the data processing unit, serialize the reception signal data, and send a third electric signal comprising the reception signal data to a network device that the pluggable optical network unit is plugged into; and a management unit configured to monitor operation status of the transceiver assembly and the data processing unit, wherein the management unit is configured to modify the third electric signal in accordance to the operation status of at least one of the transceiver assembly or the data processing unit, wherein the management unit is configured to produce a control signal to modify the third electric signal if the operation status indicates that at least one of the transceiver assembly or the data processing unit malfunctions.
