Automatic gain-controlled bidirectional add-drop amplifier for dynamically reconfigurable bidirectional WDM networks

Abstract

An automatic gain-controlled bidirectional add-drop amplifier (BADA) has been realized based on a pump control technique for use in bidirectional wavelength division multiplexed (WDM) networks. By using the BADAs, we demonstrate a dynamically reconfigurable bidirectional WDM ring network. The BADA enables dynamic add-drops of wavelength-interleaved bidirectional signals and protects surviving signals against the impairments induced by dynamic network reconfigurations.
