MANUFACTURE OF OPTICAL FIBER

摘要

An optical fibre capable of monomode transmission in, and having a wavelength of zero dispersion in, the 1.55 mu m window and having a core comprising silica and germanium dioxide and a cladding comprising silica is drawn from an appropriate preform at a temperature in the range from 1900 DEG C. to 2000 DEG C. Fibres thus produced have low loss compared with fibres drawn at higher temperature.
