Item	Description
Parameter Type	Parameter type: TxPower(dBm): indicates the transmission power of the optical module, in dBm. RxPower(dBm): indicates the receiving power of the optical module, in dBm. Current(mA): indicates the current of the optical module, in mA. Temp.(ºC): indicates the temperature of the optical module, in degree Celsius. Voltage(V): indicates the voltage of the optical module, in V.
Current Value	Current value of a parameter. lanei/Lanei indicates a physical channel. This information can be displayed after Current Value of TxPower(dBm), RxPower(dBm), and Current(mA) of the 40GE and 100GE interfaces.
Low Alarm Threshold	Lower alarm threshold of a parameter.
High Alarm Threshold	Upper alarm threshold of a parameter.
Status	Status of the optical module: Normal: The value is within the normal range. Abnormal: The value is not within the normal range. –40: The power is low.
