Coordinated Transceiver Validation via Trace Identifiers

The patent merges the validation processes of mated transceivers by coordinating loopback tests between paired transceivers. The system combines individual transceiver validation with joint validation of the O-E-O interface, ensuring that both transceivers in a pair are validated together rather than independently. This merging approach eliminates the information loss about synchronization and intermediate interface connectivity.

The patent performs preliminary coordination between mated transceivers before actual traffic propagation. By executing coordinated loopback tests that validate both optical and data plane connectivity in advance, the system ensures complete connectivity assurance before service activation. This preliminary action prevents later failures without significantly impacting validation speed.

The patent implements feedback mechanisms where each transceiver reports validation results to a central controller, which coordinates the overall validation process. The system uses trace identifiers to track test results and provides feedback loops that automatically determine whether additional validation is needed. This structured feedback approach manages complexity by automating coordination rather than requiring manual complex test sequencing.

The patent maintains continuous validation action by having trace identifiers propagate through both transceivers in the pair without interruption. The coordinated loopback test ensures continuous verification of the complete signal path including the O-E-O interface. This continuous validation approach verifies data plane connectivity efficiently by keeping the test signal actively circulating rather than using discontinuous or repeated testing sequences.
