laser group, drive circuit is connected with DFB laser group and
radio frequency selection output ware, DFB laser group is connected with monitoring module, monitoring module is connected with
radio frequency selection output ware, radio
frequency selection output ware is connected with
optical filter module and main control module, main control module is connected with current filter module.The
system of the application realizes accurate stable drive control to different
wavelength DFB laser, can selectively open the laser
signal output channel of a road;First, filter out the interference
wavelength and
noise in optical
signal, remove low-frequency
signal in output signal again, ensure the accuracy of output signal;Realize the data communication of circuit
system and host computer, can display various data of circuit
system in real time, and promptly analyze and process.
