Abstract
The invention discloses an adaptive-range optical cable measuring device, and the device comprises an analog signal conditioning module, a nonlinear sweep frequency correction module, an analog-digital conversion module, a digital signal processing module, and a laser frequency control module. The analog signal conditioning module is connected with a to-be-measured optical fiber through a diversity device. The analog signal conditioning module carries out the unidirectional signal transmission with the nonlinear sweep frequency correction module and the analog-digital conversion module. The laser frequency control module emits laser to the to-be-measured optical fiber and the analog signal conditioning module. The laser frequency control module, the nonlinear sweep frequency correction module and the digital signal processing module are in bidirectional connection with an interface processing module through a control bus. The analog-digital conversion module and the digital signal processing module are in bidirectional connection with the interface processing module through a data bus. The device can automatically adjust the test range according to the length of the measured optical fiber.
