Apparatus and process for the fabrication of optical fibres. |
摘要 |
<p>The apparatus is composed of two coaxial crucibles (3, 4) the outer one (4) presenting a low-softening temperature, so that it might be drawn with the raw materials. Thus a fibre is obtained with an outer coating which protects it against atmospheric agents. According to this process raw materials are used allowing the fabrication of fibres which may be used to transmit optical radiations with wavelengths longer than 5 mu m, with an attenuation minimum lower that 10<-3> dB/km.</p> |
