Abstract
We describe the fiber system of the Dark Energy Spectroscopic Instrument (DESI). Its primary science goal is to provide a survey of 14,000 square degrees of the extragalactic sky using the Mayall 4m telescope in five years. The fibre system will provide a multiplex gain of 5000 so that more than 20 million galaxies can surveyed. Applying a number of tests to the survey dataset should allow the evolution of the equation of state of the universe to be determined to greater accuracy than before. The fibre system will provide a multiplex gain of 5000 with very high levels of performance.
