Query: Automated testing of optical fibres: towards the design of the Maunakea
  Spectroscopic Explorer Fibre Transmission System   We present the results of an automated fibre optic test bench constructed at
the University of Victoria as part of the Maunakea Spectroscopic Explorer (MSE)
Fibre Transmission System (FiTS). In preparation for MSE-FiTS, we have begun
characterizing the focal ratio degradation (FRD) of candidate multi-mode fibres
with the ultimate goal of testing all ~4000 MSE fibres. To achieve this, we
have built an optical bench to perform an automated version of the collimated
beam test. Herein we present the design of the bench and discuss the automation
of components by introducing the Big FiTS Fibre Wrapper (Big FFW), our
open-source automation software. We conclude with the results of tests
performed using the Big FFW on a sample of candidate fibre, comparing the Big
FFW results against those found using manual methods. Our results suggest that
the candidate MSE fibre meets the science requirement of < 5% FRD at f=2 and
less than 1% disagreement between both measurement methods.
