Abstract
Some embodiments provide a device that includes an optical module manager, an optical power manager, and a notification manager. The optical module manager may be configured to poll an optical module coupled to the device for received optical power values. The optical module manager may be further configured to receive a received optical power value. The optical power manager may be configured to determine a baseline power value based on the polling of the optical module. The notification manager may be configured to generate a notification when the received optical power value differs from, e.g., falls below, the baseline power value by a threshold amount. The notification indicates that a tampering of optical signals transmitted to the device may have occurred.
