Transmission system optical wave division multiplexing power signal command having optical transmission channel with attenuators individually optical drive signal fed/optical sub system feeding

摘要

The system of individual command of power signals has optical transmission channels (wd1..wdn) with optical attenuators (VoA) feeding an optical sub system. Each optical attenuator can be commanded separately. The individual drive signals (ps1..psn) are detected inside the optical sub system and each optical attenuator is set as a function of the drive signals.
