Abstract
Disclosed herein are an optical link monitoring apparatus and method. The optical link monitoring apparatus and method are configured to identify a root cause of faults in an optical link while distinguishing between loss and reflection by combining signal quality metrics with received optical power.
Claims20
An optical link monitoring method, comprising:
- identifying a root cause of faults in an optical link by combining signal quality metrics with received optical power to distinguish between loss and reflection.
An optical link monitoring apparatus, comprising:
- a memory configured to store at least one program;
- and
- a processor configured to execute the program,
- wherein the program is configured to identify a root cause of faults in an optical link by combining signal quality metrics with received optical power to distinguish between loss and reflection.
