Process and system for joining optical fibres without Fresnel-reflection, variable optical attenuator and system, using the same for measurement of the influence of the reflection-rate on an optical line. |
摘要 |
<p>The present invention relates to a process for joining optical fibres, characterised in that it comprises the steps consisting in i) carrying out a fairly coarse controlled polishing of the interface (5) of the fibres (1) to be connected, ii) dipping the end of the fibres (1) into a concentrated hydrofluoric acid solution, and iii) aligning and then connecting the fibres (1) with the use of an index adaptor.
<??>The invention further relates to a variable optical attenuator and a system utilising this attenuator to measure the effect of the level of reflection on an optical line.
