摘要 |
<p>In the case of fibre-optic amplifiers, the input light power is monitored in order to switch off the system in which it is contained, or individual system components, for example the fibre-optic amplifier itself, in the event of deficient input light power. In known fibre-optic amplifiers, a part of the input light power is extracted for this purpose through a coupler. However, these couplers produce disadvantages; for example deterioration of the signal-to-noise ratio. In the fibre-optic amplifier according to the invention, a device (4) is used for monitoring the input light power which extracts and evaluates the pumping light not absorbed in the optical waveguide section (2). <IMAGE></p> |
