| Zusammenfassung: | The invention relates to a optical switch, and in particular to an optical switch and a method of controlling an optical switch for attenuation of an optical signal.
An optical switch comprising switching means arranged to switch an optical signal by redirection of the optical beam path of said signal, wherein said optical switch is arranged to misalign the optical beam path so as to provide a predetermined optical output power. Thus a switch can be directly used to attenuate a signal, instead of utilising separate attenuators. |
