This paper discusses how hydrogen-isotope doping of a single-mode W-type fiber lightguide with fluorosilicate cladding affects its additional optical losses under bending of the fiber and γ irradiation. It is established that introducing stable OH− and OD− groups into the core of a lightguide fabricated by modified chemical vapor deposition reduces its optical losses when it is bent but does not increase the radiation–optical stability.
