SETT ATT FRAMSTELLA EN OPTISK FIBER ELLER EN FIBERFORFORM |
| 摘要 |
A rod of silica 14 is inserted into a substrate tube 10 whose bore is lined with a layer 11 of material having a refractive index less than that of silica. This layer 11 is itself covered with a layer 12 of silica. The assembly of the rod and tube is drawn into fibre, or its components are fused together to form a solid cross-section optical fibre preform. |
