Abstract

The fibre has a core, with a sheath possessing a lower refractive index (RI) than the max. RI of the core; and the fibre is drawn from a rod blank. To make the blank, CVD is used to make a loose core powder (a) known as white soot, which is shaped e.g. by pressing into a porous core blank rod (a). Rod (a) is then located on the axis of a mould. CVD is then used to make a sheath powder (b), which is fed into the mould and pressed onto rod(a) to make a blank (a,b), which is sintered to form a vitreous blank drawn into fibre. The powders (a,b) are pref. made by flame hydrolysis or in a reactor surrounded by a ring burner, resistance furnace or an h.f. induction coil or microwave generator for plasma-CVD. Blanks of high purity can be made.
