METHOD AND SYSTEM FOR FAULT RECOVERY IN AN OPTICAL NETWORK

摘要

A system for fault recovery in an optical network may include an initial loading equipment (ILE) apparatus configured to supply power to a set of channels over a first communications link of the optical network, the set of channels including data channels and spare channels, and a control system configured to detect an optical power level over the data channels of the first communications link and determine whether a Q-factor corresponding to the data channels of the first communications link is below an error correction threshold, the control system configured to alert the ILE apparatus to adjust its optical power output over the spare channels upwardly based on the determination that the Q-factor is below the error correction threshold to increase the Q-factor.

1. A system for fault recovery in a terminal of an optical network, comprising:
an initial loading equipment (ILE) apparatus configured to supply power to a set of channels over a first communications link of the optical network, the set of channels including data channels and spare channels; and a control system configured to detect an optical power level over the data channels of the first communications link and determine whether a Q-factor corresponding to the data channels of the first communications link is below an error correction threshold, the control system configured to send a first alert the ILE apparatus to adjust its optical power output over the spare channels upwardly based on the determination that the Q-factor is below the error correction threshold to increase the Q-factor.
