Manufacture of high proof-test optical fiber using sol-gel. |
摘要 |
<p>Incidence of breakage in optical fiber drawn from sol-gel produced preforms is reduced by treatment of the still-porous glass by use of a chlorine-containing, oxygen-free gas mixture. Improved satisfaction of proof-test requirements to at least 100 kpsi is assured by size reduction of unassimilated discrete particles in the fiber. <IMAGE></p> |
