Abstract :
In this letter, a novel scheme for module implementation of power equalization in wavelength-division-multiplexed (WDM) all-optical networks is proposed. The power equalization and the power amplification are united into one module and the node isolation principle is applied. The simulation shows that ours is more explicit and efficient than the traditional schemes. The larger number of cascaded nodes is permitted and the system performance (signal-to-noise ratio) can be kept without deterioration. Consequently, a feasible novel solution to power management in WDM all-optical networks is presented.
