LSST 2017 Patch

This patch, designed and distributed at LSST 2017, depicts LSST’s progress in establishing 100-gigabit-per-second class fiber optic networks to connect LSST Sites in Chile and the United States.To date, more than 800 kilometers of dark fiber have been installed by Telefonica, connecting the Cerro Pachón and Cerro Tololo summits, the AURA Gatehouse, the AURA Recinto in La Serena, and REUNA sites both in La Serena and in Santiago.The fiber paths provide redundancy in case of failure to ensure that the LSST data always gets through. Dense Wave Division Multiplexing (DWDM) equipment has been purchased to light the fibers; this equipment will be installed and demonstrated in 2017. In addition, LSST’s Florida International University/AmLight partner has contracted for LSST to use both a 100-gigabit-per-second ring of fibers connecting Santiago and Miami, Florida, and a 100-gigabit-per-second spectrum reservation on the new Monet submarine cable connecting Sao Paulo and Boca Raton, Florida. In partnership with RNP and ANSP of Brazil, this spectrum will be extended via a new terrestrial link connecting Santiago and Sao Paulo. Finally, as of July 2017, LSST is in early discussions with ESNet to provide connectivity between Florida and LSST sites in the U.S.
