Automatic gain-controlled bidirectional add-drop amplifier for dynamically reconfigurable bidirectional WDM networks
Photonics Technology Letters, IEEE（2003）
摘要
An automatic gain-controlled bidirectional add-drop amplifier (BADA) has been realized by incorporating pump-controlled bidirectional and unidirectional EDFAs. By using the BADAs, we demonstrate a dynamically reconfigurable bidirectional wavelength division multiplexed (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.
