| 摘要 |
For a simple determination of the bandwidths of optical fibers, the invention proposes a method that provides for the coupling of light with a first optical power and a first modulation frequency into an optical fiber, as well as measuring a first signal level as a function of the optical power of the light of the first modulation frequency passing through the optical fiber, coupling light with the second optical power and a second modulation frequency into the optical fiber, measuring a second signal level as a function of the optical power of the light of the second modulation frequency passing through the optical fiber, and determining the bandwidths of the optical fibers as a function of the first and second coupled optical [power and/or] the measured first and second signal levels while using a predetermined specification that describes the frequency-dependent attenuation response of the optical fiber, wherein the first and the second modulation frequencies have essentially the same value. The invention further proposes a corresponding electronic component for performing the method, which is constructed, in particular, as an integrated circuit.
