Note The value for the Optical Tx Power (in dBm) equals ten times log (Tx Power in mW). If the Tx
Power value is 3 mW, then the Optical Tx Power value equals 10 * log (3), which equals 10 *
.477 or 4.77 dBm. The Optical Rx Power value behaves similarly. If the Tx Power or the Rx
Power is zero, then its dBm value is undefined and is shown as N/A (not applicable).
This example shows how to display detailed diagnostic monitoring data , including calibrated values,
alarm and warning thresholds, A 2D readouts, and alarm and wa rning flags. The A2D readout s are
reported separately in parentheses only if they differ from the calibrated values:

mA: milliamperes, dBm: decibels (milliwatts), NA or N/A: not applicable.
++ : high alarm, + : high warning, - : low warning, -- : low alarm.
A2D readouts (if they differ), are reported in parentheses.
The threshold values are calibrated.
