In the early 1960s, what was Snitzer widely credited for achieving regarding light attenuation in glass fibers?

Answer

Developing fibers with significantly lower light attenuation, sometimes orders of magnitude better than previous figures

Snitzer's fabrication techniques dramatically reduced light loss, moving from extremely high initial attenuation figures to numbers orders of magnitude better, making the fiber practical for light sources.
