| 摘要 |
<p>The invention relates to a method and means for measuring the power loss in a fibre optical connector of the type which includes an optical fibre (3) for transmitting high optical power, specifically power exceeding 1 kW, and wherein incident radiation (1) falling outside the fiber core is absorbed at least partially in a flowing coolant (2). The connector comprises means, for instance thermo-elements (8), for measuring the temperature difference (ΔT) between the in- and outgoing coolant as a measure of the generated power loss. Preferably the flow speed is adapted to different power losses.</p> |
