10Gbps Full Rate Clock Recovery Device 2/4 Frequency Division
U9710 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.
U9710 CDR has a SFP optical port, which is suitable for SFP
encapsulated conventional SFP, SFP+, OLT SFP and other optical
modules. It only needs the receiving end of the optical module to
convert the optical signal to the electrical signal, and then
extract and output the clock of the electrical signal. Clock signal
is mainly used for the trigger signal of oscilloscope. This device
self-adapts to the rate and does not require software
configuration.
The 10G clock recovery instrument is mainly used to restore the
clock frequency of the signal source to ensure the stability and
reliability of data transmission. In some high-speed communication
systems and network devices, the data transmission speed is very
fast, so a very precise clock signal is needed to ensure that the
data is transmitted synchronously. If the clock signal is deviated
or unstable, it can result in data loss or transmission errors.
