Abstract

With this work we summarise the design evolution and challenges of the Fiber-Link module for ANDES (ArmazoNes high Dispersion Echelle Spectrograph), the high resolution spectrograph for ESO ELT. The instrument just passed the System Architecture Review of Phase-B1. The Fiber-Link subsystem carries and redistributes the light from the telescope to the spectrometers via several selectable optical paths. The general updated layout for the Fiber-Link module is presented giving element characteristics and obtained performances. First results from laboratory test and prototype activities are also shown. Moreover, we include the reasoning for selected solutions and explaining how requirements are met. Finally, we summarise the compliance against the science top-level requirements and the issues to address moving forward.
