| 英文摘要 | Attenuation of an optical fiber is measured by transmittingan optical signal having a predetermined wavelength to the fiber,and FSK modulating the optical signal with informationidentifying the wavelength and transmitted power of the opticalsignal. At a receiver, the optical signal is detected and theinformation is recovered by demodulation. Wavelength-dependentsensitivity information for the detector is read from a store independence upon the wavelength information and used to controlthe gain of an amplifier for amplifying a subsequentlytransmitted continuous wave optical signal used for attenuationmeasurement. The received power level of this optical signal isconverted into a digital value and used with the transmittedpower information to determine the fiber attenuation at thepredetermined wavelength. |
