This paper documents the fiber R and D for the CMS hadron barrel calorimeter
(HCAL). The R and D includes measurements of fiber flexibility, splicing,
mirror reflectivity, relative light yield, attenuation length, radiation
effects, absolute light yield, and transverse tile uniformity. Schematics of
the hardware for each measurement are shown. These studies are done for
different diameters and kinds of multiclad fiber.Comment: 23 pages, 30 Figures 89 pages, 41 figures, corresponding author: H.
