The value of tmnxCohOptPortModTxTurnUpStates indicates the completed TX turn-up states of the coherent optical module. init - The entry state, in which configuration of the TX path is performed. laserTurnUp - This state begins the process of tuning the TX laser and locking devices on the TX path. laserReadyOff - When the laser is ready for operation, but light emission is suppressed, this state is entered. laserReady - This state brings the laser to full power and frequency lock. modulatorConverge - This state enables the TX modulator driver and waits for convergence of the modulator automatic bias control loop. outputPowerAdjust - This state sets and controls the TX output power using a VOA.
