U9740B CDR (clock recovery instrument) is mainly used to provide
clock recovery signals in the test environment without triggering
the clock, so as to use the sampling oscilloscope to test the
optical eye diagram of the device. Typical application is the test
of optical network equipment, or for BOB products in PON
application, because the measured equipment itself does not have
the output of the frequency division clock, the clock signal needs
to be recovered to trigger the sampling oscilloscope when testing
the optical eye map.
U9740B CDR with an FC optical interface adapter, suitable for
conventional SFP28/56, SR, LR and BIDI module optical signal
access, support NRZ and PAM4 signals, FC optical interface to
receive optical signals into electrical signals, CDR will be the
electrical signal clock extracted and output. Clock signal is
mainly used in oscilloscope trigger signal.
