| 摘要 |
<p>The present invention relates to an optical signature device (100a) for providing an optically detectable signature to an optical system (200), particularly to an optical communications network (200), wherein said optical signature device (100a) comprises an optical path (105) that can be coupled with the optical system (200). To provide high flexibility, the inventive signature device (100a) is characterized by configuration means (110) for selecting a predetermined signature which is to be provided by the optical signature device (100a), and by signature generating means (120) for generating said predetermined signature within said optical path (105) of said optical signature device (100a).</p> |
