Digital optical monitoring The digital optical monitoring (DOM) feature monitors the digital optical media for temperature, voltage, bias, transmission power (Tx), and reception power (Rx). This feature also generates event logs, alarms, and traps for any fluctuations, when configured thresholds are reached. There are four threshold levels for each of the DOM categories-temperature, voltage, bias, transmission power, and reception power as summarized in the following table: • High • High warning • Low • Low warning The OS10 DOM subsystem periodically monitors the optical transceivers for temperature, voltage, bias, transmission power and reception power changes and generate event logs, alarms, and traps when their respective values cross the predefined thresholds. Table 5.
