We report the advance on the re-assembly and commissioning of the BHROS spectrograph, its associated instrument laboratory and the planned system of telescopes. This is the largest astronomical spectrograph ever assembled in Argentina and the laboratory is also being used for other instrumentation needs of ICATE. We have installed a half meter telescope in order to test the spectrograph with on-sky sources, and we plan to install a network of telescopes feeding it via a multiple optical fiber system. In these first tests we have obtained spectra of the Sun (R100000) and Jupiter and Achernar (R40000). In 2017-2018 we plan to install and test a network of five small telescopes feeding the spectrograph with the collecting area equivalent to that of a one meter telescope, with a cost 10-25 times less in acquisition, transport, installation and operation respect to a conventional monolithic telescope.
