U9720A 32Gbaud PAM4 CDR PON/BOB Test support 25GBaud~32GBaud
U9720B CDR (Clock Recovery Module ) is mainly used to provide clock recovery signal in the test environment without triggering clock, so as to use the sampling oscilloscope to test the optical eye diagram of the device. The typical application is the testing of optical network equipment or the BOB prodUt in PON application. Because the photometric device itself has no frequency division clock output, it is necessary to recover the clock signal to trigger the sampling oscilloscope when testing the optical eye diagram.
U9720B CDR has a FC optical interface adapter, which is suitable for optical signal access of conventional SFP28/56, SR, LR and BIDI modules. It supports NRZ and PAM4 signals. FC optical interface receives optical signals and converts them into electrical signals. CDR then abstracts and outputs the clock of electrical signals, and the clock signals are mainly used for the trigger signals of oscilloscopes.
