+    STATUS    current
+    DESCRIPTION   
+        "The value of the optical parameter that is being monitored.
+
+        The range of values varies depending on the type of optical
+        parameter being monitored, as identified by a corresponding
+        object with syntax OpticalParameterType.
+
+        when the optical parameter being monitored is 'power' or 
+        'acpower', the supported range is from -1000 to 1000, in 
+        1/10ths of dBm.
+        Example: Actual power of -40 dbm is represented as -400.
+        Actual power level of +30 dBm is represented as 300.
+
+        When the optical parameter being monitored is 'laserTemp' or
+        'apdTemp', the supported range is from -10000 to 30000, in
+        1/100ths of degrees centigrade.
+        Example: A value of 2355 represents a temperature reading of
+        23.55 degrees C.
+
+        When the optical parameter being monitored is 'biasCurrent',
+        the supported range is from 0 to 1000, in 1/10ths of
+        percentage (%).
+        Example: A value of 500 represents a bias current threshold
+        of 50.0 %.
+
+        When the optical parameter being monitored is 'peltierCurrent',
+        the supported range is from 0 to 10000, in milliamperes. 
+
+        When the optical parameter being monitored is 'xcvrVoltage',
+        the supported range is from 0 to 100000, in 1/10ths of
+        millivolts.
+        Example: A Value of 115 represents a transceiver voltage
+        reading of 11.5 millivolts.
+
+        The distinguished value of '-1000000' indicates that the object
+        has not yet been initialized or does not apply.
