| Abstract: | Optical fiber loss is an important index of optical fiber quality in commuication. Under noraml conditions, We need to determine the optical loss value of each wave length in a wide spertrum for selecting the most suitable wavelength of light source. A bifrequency photoelectronic system is proposed in this paper, in which an 8 bit microcontroller is used for collecting and processing data. |
