Transponder management testing and interaction tracing

Abstract:

An apparatus such as an Optical Network Tester (ONT) may include an embedded script interpreter to interpret a script for testing an optical transponder coupled to the ONT. The ONT may identify a control based on a statement included in the script, and cause, via an electrical interface, an interaction with the optical transponder to occur based on the control. The ONT may generate a first timestamped log entry to indicate a timing of the control, detect a data path event associated with the optical transponder, generate a second timestamped log entry to indicate a timing of the data path event, and determine that the data path event was caused by the control based on the first timestamped log entry and the second timestamped log entry. The ONT may further assess operation of the optical transponder based on the determination that the data path event was caused by the control.
