A dispersion managed link for transmitting wavelength division multiplexed optical signals and method for providing the link are disclosed. In the present invention, an operation of opening an ejector lever is implemented by means of a pulling force, thereby bringing operation comfort and saving a layout space. The system is auto-referenced since it does not need any positioning device to provide the 6 degree of freedom transformations that are necessary to integrate 3D measurements in a global coordinate system while the apparatus is manipulated to scan the surface.
