PROCEDE DE FABRICATION D'UNE FIBRE OPTIQUE MONOMODE ET AMPLIFICATEUR OPTIQUE UTILISANT UNE TELLE FIBRE |
摘要 |
A single-mode preform (2) including a master preform (22) housed in an outer sleeve tube (20) is provided. An intermediate tube (21) between the master preform (22) and the outer tube (20) has a lower viscosity at the fibre drawing temperature than said master preform (22) and said outer tube (20). A method for making a single-mode optical fibre is also provided. The fibre has a more centred and less deformed core than in the prior art. By way of example, an optical amplifier may thus be produced. |
