“…42 Link control, which provides surviving channel protection against fast transients, has recently been demonstrated. 43 The scheme, illustrated in Figure 13, protects surviving channels on a link-bylink basis. A control channel is added before the first optical amplifier in a link (usually the output amplifier of a network element).…”

“…Thus, it would be desirable to synthesize a controller to minimize or reject the effects of cross-gain modulation owed to these disturbances, while also ensuring that output channels closely track their respective input signals. Although effective control methods for the EDFA exist [10], [11], these methods have focused on pump or link control for a channel add/drop. This paper studies the characteristics of input signal disturbances owed to pilot tones.…”

In this paper we propose the application of H∞ control within optical networks. Specifically, we aim to suppress the cross-gain modulation effects within Erbium-doped fiber amplifiers owed to pilot tone disturbances used for optical monitoring. Based on the characteristics of these pilot tone disturbances, we design an H∞ controller to improve transient performance of optical channels within the network. Within this paper the control system design is described and simulation results are presented.

“…To avoid this effect, several control methods have been developed [5][6][7][8][9]. One of them uses EDFA output as a feedback signal in an optical feedback control loop [5].…”

Abstract:In this paper, a disturbance observer (DOB) based erbium-doped fiber amplifier(EDFA) gain controller is proposed. In order to stabilize an EDFA gain in wavelength-division-multiplexing (WDM) channel add/drop networks, the channel add/drop is estimated based on a mathematical EDFA model and compensated using DOB technique. The performance of the proposed control method is theoretically analyzed using Lyapunov method. The performance of the proposed DOB-based gain control algorithm was investigated through simulations. Simulation results verify the excellent performance of the proposed gain control methodology.
