Abstract

There is disclosed an arrangement (100, 110, 120, 130) for converting wavelengths for bi directional Wavelength Division Multiplexing (xWDM). The arrangement (100, 110, 120, 130) comprises: at least one first transmitting system (200, 210, 220, 230, 240, 250, 300, 310, 320, 330, 340, 350); at least one first wavelength converter (500, 600, 510, 610, 520, 620, 530, 630, 540, 640, 550, 650), each first wavelength converter (500, 600, 510, 610, 520, 620, 530, 630, 540, 640, 550, 650) adapted to convert an optical signal from one of the first transmitting systems (200, 210, 220, 230, 240, 250, 300, 310, 320, 330, 340, 350) to a first converted signal, the conversion being such that the wavelength of each first converted signal conforms to a xWDM standard; a bidirectional xWDM module (400, 410, 420, 430, 440, 450, 460) adapted to direct each first converted signal in a first direction; and an optical protection switch (470) for protecting the bi-directional xWDM module (400, 410, 420, 430, 440, 450, 460). Also disclosed is a method for converting wavelengths for di-directional Wavelength Division Multiplexing (xWDM). The method comprises the steps of: converting at least one optical signal to at least one first converted signal, the conversion being such that the wavelength of each first converted signal conforms to a xWDM-standard; and directing each first converted signal in a first direction in a bi-directional xWDM module (400, 410,420,430,440, 450, 460), wherein the bi-directional WDM module (400, 410, 420, 430, 440, 450, 460) is protected by an optical protection switch (470).
