Kapron, Keck and Maurer: low-loss glass optical waveguides

What changed

Glass fiber became a credible low-loss optical communication medium.

Scientific scope

The 1970 paper's measured fibers and distinct intrinsic/total losses; later manufacturing and deployed networks are excluded.

Evidence

The linked sources identify this contribution and its scope. WRS has not independently reconstructed the scientific claims. The paper’s reported intrinsic and total losses must not be conflated, and later telecom systems and manufacturing scale are separate.
