Assignee: CIENA CORPORATION
Field: Telecommunications (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 7:
8. A network element comprising:
a plurality of modules including at least one of amplifiers, optical modems, multiplexers/demultiplexers, a controller, and wavelength selective switches,
wherein circuitry on one or more of the plurality of modules is configured to:
detect a fast fiber transient on a span based on analyzing power data, wherein the power data corresponds to at least one of optical wavelengths of traffic channels, optical service channel (OSC) wavelengths, and telemetry from a network element;
determine a specific configuration of an optical time domain reflectometer (OTDR) based on the detected fast fiber transient, wherein the fast fiber transient is an event on the span that lasts in a range of seconds and which causes errors on optical services without causing a line failure, and wherein the specific configuration includes settings related to one or more of acquisition time and pulse width of the OTDR based on the detected fast fiber transient and fiber distance such that an OTDR trace completes before an expected end of the fast fiber transient;
responsive to detection the fast fiber transient and configuration of the OTDR with the specific configuration, cause execution of the OTDR to perform the OTDR trace on the span with the specific configuration; and
determine a location of the fast fiber transient based on the OTDR trace.
