  The Maunakea Spectroscopic Explorer (MSE) is a next-generation observatory,
designed to provide highly multiplexed, multi-object spectroscopy over a wide
field of view. The observatory will consist of (1) a telescope with an 11.25 m
aperture, (2) a 1.5 square-degree science field of view, (3) fibre optic
positioning and transmission systems, and (4) a suite of low (R=3000), moderate
(R=6000) and high resolution (R=40,000) spectrographs. The Fibre Transmission
System (FiTS) consists of 4332 optical fibres, designed to transmit the light
from the telescope prime focus to the dedicated spectrographs. The ambitious
science goals of MSE require the Fibre Transmission System to deliver
performance well beyond the current state of the art for multi-fibre systems,
e.g., the sensitivity to observe magnitude 24 objects over a very broad
wavelength range (0.37 - 1.8 microns) while achieving relative
spectrophotometric accuracy of <3% and radial velocity precision of 20 km/s.
