摘要: The present invention relates to a 4-port wavelength selective router and the add/drop multiplexer using the above router. More particularly, it relates to a 4-port wavelength selective router that can effectively routes counter-propagating signals while suppressing multiple reflections generated in the bidirectional transmission systems and networks.
