OPTICAL SIGNAL MONITORING

摘要

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.

1. A device comprising:
an optical module manager configured to poll an optical module coupled to the device for received optical power values, wherein the optical module manager is further configured to receive a received optical power value; an optical power manager configured to determine a baseline power value based on the polling of the optical module; and a notification manager configured to generate a notification when the received optical power value differs from the baseline power value by a threshold amount, wherein the notification indicates occurrence of an event selected from a group consisting of a tampering of optical signals transmitted to the device, or damage to a cable.
