HEAT TREATMENT OF SILICA BASED GLASSES |
| 摘要 |
A sintered dense glass, alumina-doped optical fiber preform is stretched and is then heated to a temperature of 1490-1495.degree.C to remove bubbles without causing crystallization. Thereafter, the stretched glass body is either drawn directly into an optical fiber or overclad and then drawn into a fiber.
